As soon as I landed in Paris and stepped off the plane, I kept repeating to myself: take a deep breath, and appreciate all that this wonderful city has to offer. I have done countless hours of walking aimlessly around Paris, discovering cute hidden spots and narrow passages. I love the culture and the rich history which surrounds me in all of my visits.

Our course curriculum on this Neuroscience in Paris summer program includes visits to museums and landmarks around Paris, which broadens our perspective and gives context to some of the concepts we learn. Museums we have visited this week include the Musée de l’Orangerie, the Musée Dupuytren and the Musée de l’Histoire de la Médecine. These thought provoking visits bring me back to a topic which I have become very interested in: mindfulness.

The concept of mindfulness comes from ancient Tibetan Buddhists, and promotes one to be aware of thoughts that arise in the present moment. Merriam-Webster Dictionary uses words such as attention, alertness, awareness and observation as examples of some possible synonyms. This methodology allows increased concentration and increased appreciation of the artwork seen in museums, and allows one to truly capture and experience each moment. While at the Musée de l’Orangerie, I was in awe of Claude Monet’s Water Lilies, highlighted by a skylight.

Me at the Musée de l’Orangerie with Monet’s Water Lilies

Monet’s enormous works panned almost the entire length of the large, white oval-shaped walls. As I sat down, I employed practices of mindful-attention to really enjoy the work. Based on traditional papers, attention training represents a centripetal element of meditation practice. Meditation greatly influences one’s ability to act mindfully and it also works to improve awareness.

In an article published in Frontiers in Human Neuroscience, Desbordes et al. (2012) found that the beneficial effects of meditation training on emotional processing can likely transfer to non–meditative states. The study, titled: Effects of mindful-attention and compassion meditation training on amygdala response to emotional stimuli in an ordinary non-meditative state, aimed to test if the amygdala’s response to emotional stimuli would decrease after mindful-attention meditation training for eight weeks.

Located in the temporal lobe of the brain, the amygdala contributes to memory processing, decision-making and emotional reactions. As a main component of the limbic system, the amygdala involves many functions such as emotion, behavior, attention, sensory processing and motivation. You can think of it as the human center for emotion. Many studies (at least 10 that I know of) have found that meditation training can improve one’s attention skills, which motivated me to explore this subject.

In this study, the 8-week mindful attention training involved personal awareness in addition to a focus on external environments. This training involves mindfulness of breathing, mindfulness of mental events and awareness of awareness (sounds strange, I know, but bear with me). This study also examined the effects of compassion-based meditation on amygdala activity, but my primary interests lie in mindfulness meditation since it directly relates to art appreciation, and to my recent museum visits. During recordings, participants did not enter a meditative state. This methodology was used to see if the meditation has a long lasting effect. This study examined participants aged 25-55 with no prior experience in meditation. Researchers took two fMRI’s; the first occurred three weeks prior to the meditation intervention, and the second, three weeks after. The fMRI, also known as a functional magnetic resonance imaging scan, measures brain activity through changes in blood flow (Wikipedia). The researchers presented various images to the participants, just as I was looking at various Monet paintings. The scans showed decreased brain activation levels (blood flow) in the right hemisphere of the amygdala (associated with negative emotions) but not in the left.

There was no significant difference in activation levels before training, meaning that the introduction of the meditation practice changed the blood flow in the amygdala. Researchers also found that as you increase the amount of time you spend meditating, blood flow in the right amygdala continues to diminish. These results led to the conclusion that practicing meditation can affect your emotional response to stimuli.

Thich Nhat Hanh, a pioneer in this work, promotes mindful living in daily activities, relationships, and health behaviors. Nhat Hanh focuses on the concept of “interbeing”, which describes the interconnection of all things around us. Looking at Monet’s paintings, I thought about the interdependence of all the elements in the painting itself, and how all of those elements combine to make the final masterpiece. For example, the lilies rest on the water and depend on it for support, the flowers grow on those lilies, and the sun and moonlight hit the water to create beautiful reflections at different times of day.

Monet’s Water Lilies

From another perspective, I thought about the work Monet put into those paintings, specifically, the different colors and brushes and tables he may have used. Mindfulness allows one to go deeper into these works of art and see them not as stand-alone objects, but as a multitude of interconnected elements. The authors hypothesized that their results may indicate an improvement in attention skills. This research does not stand-alone. Previous research also determined that experimental tasks which involved rating based on emotions, reduced amygdala activity (Hariri et al., 2000; Taylor et al., 2003; Hutcherson et al.,2008a). Furthermore, another study by Taylor et al. (2012) examined connections between multiple brain areas, and found that meditation training changes connections between certain areas, which could also explain increased awareness. Therefore, we can understand reduced amygdala activity as an increase in attention and awareness, an ideal practice to employ during museum visits.

I hope to expand my knowledge in this field by engaging in Emory’s Cognitively- Based Compassion Training (CBCT). This training program encourages students to engage in meditative and reflexive practices in their day-to-day lives.  If you have any interest in learning more about meditation, optimism, well-being, empathy and many more happiness boosting topics, I encourage you to visit http://www.happify.com.

Thich Nhat Hahn Quote:

“Parlez-vous anglais?” I find myself saying this phrase in almost every interaction I have with a French speaker–ordering food, asking for directions, shopping. The answer I dread occasionally follows, “Non…” The first thought that comes to mind is “I should have kept up with French in elementary school.” Then I resort to my next resource: my hands. Hand gestures not only help me communicate but help me understand what the other person is saying. Over my past two weeks in France, much of my French vocabulary stems from these gestural experiences.

This resource came in “handy” (pun intended!) when I found out, after returning home from a group project meeting at 1am, that my room key deactivated. I went to the security guard in my dorm and said, “Bonsoir, Parlez-vous anglais?” His reply: “Non…” I proceeded to try to tell him through hand gestures and pantomime that my card does not work. He responded back to me in rapid French. Surely, the puzzled look on my face cued him to speak slower and provide some supplemental help: gestures. I understood and still remember nearly all the words he said after that cue.

Cité Universitaire – Where I live!

Why did I understand and can now remember the words the security guard said? In a study done by Mayer et al. (2015), researchers found that self-performed gestures enhance learning a foreign language. The study supports the cognitive neuroscience theory known as multisensory learning, a concept that “attributes the benefits of enrichment to recruitment of brain areas specialized in processing the enrichment” (Mayer et al., 2015).

How the human brain most effectively learns foreign languages still puzzles many researchers. Typical in-classroom settings use verbal learning techniques to teach new languages; however, Mayer et al. (2015) investigated the benefits of enriched learning methods, such as pictures and gestures, as compared to learning methods without enrichment, verbal learning. While they found learning with self-performed gestures more effective than learning with pictures, both enriched approaches benefitted the learner more than the utilization of strictly verbal learning.

Mayer et al. (2015) conducted the research by having two experimental groups. In the first experiment, 22 German adults, split into groups of seven or eight to simulate a classroom learning environment, learned foreign language words under three conditions. The participants first learned words by watching a large projection screen where a person performed gestures symbolic to the word’s meaning and then repeated the gesture. The second condition utilized the photo enrichment approach, where participants looked at a picture projected on a large screen and then, as the picture was presented a second time, traced a line on the picture with their finger in the air. The third condition acted as a control condition, where participants learned words with no enrichment.

My experience with the security guard somewhat mimicked the gestural enrichment condition of Experiment 1. As the security guard said to me, “Je” (pointing to himself), “donne” (pantomiming giving me something), “vous” (pointing to me), “un clé” (holding up the new key card), “fin” (crossing his hands), “après une jour” (distinguishing with his finger today versus tomorrow). As he made these gestures, I tried to follow him to make sure I understood what he was saying. Surely enough, I did. Even better, almost a week later, I remember the meaning of those words!

In the study, Mayer et al. (2015) confirmed the benefits of enriched learning through functional magnetic resonance imaging (fMRI) of the brain. After a week of learning foreign language words under the three conditions, the researchers collected brain images measuring blood-oxygenation-level-dependent (BOLD) responses, a method of fMRI to observe activity in the brain or other organs, while they presented the participants with auditory foreign words and asked them to select the correct translation on a response screen.

For translated words learned with gesture enrichment, the fMRI images show brain activity in the biological motion superior temporal sulcus (bmSTS), an area sensitive to perception of others, and motor areas of the brain. For translated words learned with picture enhancement, the fMRI images show brain activity in the lateral occipital complex (LOC), an area of visual-object sensitivity.

A) LOC (Lateral occipital complex) BOLD responses
B) bmSTS (biological motion superior temporal sulcus) BOLD responses
C) Correlation of gesture and picture enrichment benefit
Figure S2 – Mayer et al. (2015)

In further analysis of the fMRI images, Mayer et al. (2015) found significant correlations between gesture and picture enrichment with distinct brain activity in sensory and motor areas as compared to neuronal activation for words learned without enrichment. The data show that using the gesture enrichment benefited the learner more than the picture enrichment; however, both enrichments benefited the learner more than no enrichment.

Mayer et al. conducted a second experiment where another 22 German adults learned foreign language words under the three enrichment conditions, but participants did not imitate the gesture or trace the picture, thus excluding a motor component. Photo enrichment benefitted the learner more than gesture, in this case; however, looking at the study as a whole, gesture enrichment enhanced learning the most.

Experiment 1 and 2 results demonstrating the benefits of enriched learning approaches to foreign words
Figure S3 – Mayer et al. (2015)

Each finding of the study supported the hypothesis that implementing enriched learning methods, as compared to learning methods without enrichment, would increase correct translation of foreign language words. The study also continuously supported the multisensory learning theory in that distinct brain activity occurred in sensory and motor areas of the brain when translating foreign words that participants learned with enriched learning approaches. Not only can language teachers use the findings of this study to enhance their students’ learning but also future researchers can apply the data to better understanding learning disorders, such as dyslexia or processing issues. While overall a compelling article, I believe Mayer et al. (2015) should have tested whether being monolingual, bilingual, or polylingual prior to the study had any confounding effects on acquisition of foreign words.

My enriched learning experience with the very patient and kind security guard probably influenced why I can remember the meanings of those French words. By watching him gesture almost every word and by copying these gestures, politely of course, to internalize them, I employed both visual and kinesthetic associations to the French words, and thus, enriched my learning of these words. Hopefully I experience more enriched learning of French words… without getting locked out of my room!

After exploring Paris for two weeks, I have come to love the sights, smells and tastes of its beautiful streets. I already found my favorite routes for traveling to class and finding new restaurants. I know where to go to find a quiet garden to study in, or a quaint little restaurant to have the most amazing gnocchi dinner. As I continue to wander around, my understanding of the layout of the city is coming together to form a cohesive picture. As any naïve tourist would report, I felt like a natural Parisian after my first successful solo excursion on the metro. And as that same naïve tourist would inevitably soon discover, I was not nearly as good at navigating as I assumed.

On one of my first days in Paris, I was lucky to be able to spend the afternoon with my boyfriend who was touring around Europe. At the end of the day, I wanted to go to a small restaurant in Montmartre that I visited over three years previously. I assumed I would easily be able to figure out the way once we got to Montmartre.

Patrick and me at the Louvre

When we arrived at the metro line to go up to Montmartre, we found that it was closed, and a sign directed us to the next stop along the same line. We walked over and to our frustration, that stop was closed as well, with a sign directing us back down to where we had come from. Not ready to be discouraged, we decided to get on a different line at that station, and try to make connections until we were near our destination. Over an hour later, we found ourselves standing on an unfamiliar street, without wifi or any real idea of where we were. We oriented ourselves to walk north, since we had no better plan for how to begin.

All of our stops through Paris! The green dot shows the restaurant in Montmartre, the yellow dot shows the metro stop we got off at, and the blue dot shows where I started and ended my day. The red dots are all of the stops along the way.

Upon reflection, I realized that the only reason I managed to eventually eat dinner that night, was because of my ever-resourceful hippocampus. Well known for its role in memory consolidation, the hippocampal formation is now recognized to be highly involved in spatial navigation, in part due to the presence of grid cells and place cells (Jacobs, et al., 2013). Oscillations in place cell firing occur in a cycle called the theta cycle, to help orient oneself in space (Wikenheiser & Redish, 2015). Unlike place cells, which only fire for very specific locations in space, grid cells in the entorhinal cortex represent space in a triangular coordinate system (Jacobs, et al. 2013). Many research studies have explored the presence and function of place and grid cells in rodents, bats, and primates. One study showed that rats have a hippocampal cognitive map, representing specific objects in specific locations, and only secondarily focusing on object identity (Manns & Eichenbaum, 2009).

The hippocampus and the entorhinal cortex are both part of the hippocampal formation.
http://www.nature.com/nrn/journal/v12/n10/fig_tab/nrn3085_F1.html

In a recent study, researchers directly obtained electrophysiological recordings from humans while they were undergoing treatment for epilepsy (Jacobs, et al. 2013). The subjects performed a virtual spatial learning task in between clinical procedures. The subjects used a joystick to navigate a virtual environment, and during testing they needed to travel directly from one object to an invisible goal object. Microelectrodes placed in the subject’s brain recorded neural activity throughout the task. The data provide evidence that humans, just like other mammals, have an allocentric spatial cognitive map, complete with grid cells and place cells. This means the location of one object is defined in relation to the location of others.

All of these data help to explain my journey to Montmartre. As I pictured myself walking through the area that I wished to go, my hippocampus fired to simulate the future, goal-directed action (Wikenheiser & Redish, 2015). Just as your place cells fire to represent where you are, they can also fire as you “replay” an experience in your mind. When I found the train platform closed, my interconnected hippocampus likely communicated with the reward center of my brain in the ventral striatum to link the failed expectation to the place (van der Meer, & Redish, 2009). Once I started navigating through the highly unfamiliar area, the neurons in my hippocampus and entorhinal cortex must have fired in an effort to link novel stimuli to spatial context. Evidence suggests that my instinct to “walk north” was because exploration relies heavily on grid-cells with direction sensitivity (Jacobs, et al. 2013). As the scenery around me started to become more familiar, specific cells throughout my hippocampal formation responded to locations, landmarks, and directions that triggered unique firing patterns (Jacobs, et al. 2013). Once I arrived at my final destination, my hippocampal neurons would have fired to help many areas of my brain realize that this restaurant was familiar, and that I should soon expect a reward in the form of delicious French food.

Well worth the journey

I am looking forward to many more adventures through Paris, and I now know much more about how my hippocampus can dependably orient me in space. I also learned that I probably should start carrying a map.

Dear Friend,

What is it about quintessential European cities that tenderly pulls at our heartstrings and calls to us? For me, it is the simple art and beauty sprinkled throughout the cities, hidden in almost every little detail. This is my second time and Paris, and after stepping out of my dorm in Cité and catching the Métro to the heart of the city, I found myself in awe while exiting the station at Saint-Michel-Notre Dame, reveling at the scene around me. As I walked around the City of Light, brimming with art and culture, I made a mental note of the places that I wanted to visit.

Finally, when the first weekend crept around the corner, some of my friends and I decided to take advantage of the leisure time we had and partake in touristy activities around Paris. After making a brief stop at the Latin Quarter to grab a quick bite, recharging ourselves, we headed to Notre Dame. Upon arrival, the hordes of people faded into the background, and I marveled at the grand façade of the cathedral before me, still standing tall and strong. It’s hard to believe that Notre Dame is over 800 years old!

The bells (though not ringing) of Notre Dame!

Upon following the throng of people into the cathedral, we were hit by a peaceful silence that really allowed us to soak in the scene encompassing us. We strolled along the pews, pausing here and there to appreciate the curves and contours crafted into the stone, scattered with a multitude of stained glass windows here and there.

The glorious Notre Dame from inside.

We spent a good thirty minutes inside the church before deciding to proceed with the tower climb. However, after waiting in the shade for a grueling hour and barely moving an inch in line, we made a quick change of plans and headed to the gothic chapel Sainte-Chapelle, a hidden gem which houses some of the most important relics of Christianity. The chapel is embedded from plain sight by the Palais de Justice and just a mere five minute walk away from Notre Dame. We were able to get inside (much faster than waiting in line for the tower!) and boy, was it rewarding. I was awestruck by the architectural beauty, though this one was different than Notre Dame’s. Stained glass windows lined every wall, detailing stories encrypted in the Bible.

Stained glass windows encompassing Sainte-Chapelle.

After seeing both Notre Dame and Sainte-Chapelle, I was intrigued by how appreciative my friends and I were of such places, and this piqued my interest, so I decided to do a little research. I came across a rising field in architecture that combines neuroscience and beauty: neuroaesthetics. Neuroaesthetics has become increasingly popular and focuses on the neural processes involved with our perception and interpretation of finding works of art aesthetically pleasing (Leder 2013). Our intuitions that explain how we feel can be reflected in physical features around us (Vartanian et al., 2013), which could explain why we all felt at peace while walking among the churches.

Appreciating the beauty of Sainte-Chapelle, while not yet knowing the mechanism of how this happens.

More recent theories involve how such architectural designs can lead to particular behavioral outcomes. After further research, I found an article regarding the effect of architectural contour lines on aesthetic judgments. The researchers hypothesized that more curvaceous structures were more likely beautiful and cause people to enter them. They further postulated reward pathways within the brain triggered judgments in response to aesthetically pleasing objects (Vartnanian et al., 2013).

In order to test their predictions, experimenters placed participants in a functional magnetic resonance imaging (fMRI) scanner and presented images of varying contour designs. The researchers then asked participants two questions regarding the image: whether or not it was beautiful. The images portrayed rooms that had many curves (curvilinear) or straight lines (rectilinear), and within these they had either high or low ceilings and were open or enclosed spaces.

So what did this study find? Behaviorally speaking, participants rated the curvilinear spaces more beautiful and pleasant to look at than the rectilinear ones, though contour did not have any effect on approach-avoidance decisions. At a neural level, curvilinear structures activated the anterior cingulate cortex (ACC) of the brain, which previously proved its involvement in processing aesthetic images (Brown et al., 2011). The ACC, in turn, is connected reward processing via the main reward mechanism system in the brain, the orbitofrontal cortex (OFC). The findings therefore show that humans find that curvier structures are visually appealing and linked through the reward system in the brain.

How does all this research relate to the various buildings I’ve seen throughout Paris? Well, most of the interior in Notre Dame and Sainte-Chapelle were curvilinear, which explains why I felt blissful while absorbing the scene around me. That being said, we can still find rectilinear structures pleasant to view. Take the controversial pyramid outside the Louvre, for instance. Though it represents a clash between old and new, it possesses its own unique beauty.

Next architectural wonder: the Louvre!

And that takes me to where I will hopefully be heading in my next journey through Paris! After spending a day doing homework at the beautiful Jardin des Tuileries just the other day, a few of us made a quick stop to check out the Louvre. We have not been in yet, but we shall go in soon, all in due time.

That’s it for now. I’ll talk to you later!

Sincerely,

Kaavya Mandi

Dear Mom & Dad,

Not gonna lie, I have been talking to strangers despite your safety warnings about pick-pocketers and creepers. To my pleasant surprise, all my stranger-interactions have been positive. Maybe it’s due to the special neural network that relates empathy and strangers (Rameson, 2012). I gave a lost French lady directions to the metro, and couple of days later, this guy gave me directions to Notre Dame. I also ran into a group of French military students who were thrilled to see Americans. I wish I could capture all these moments as accurate as possible, but sadly, the dynamic nature of memories and their vulnerability to change makes such task extremely difficult (Yates, 2011). Regardless, Paris and I have been getting along just fine.

stranger danger at Notre Dame? 1st year French military students studying engineering.

You probably would have had a heart attack at fete de la musique aka a place full of strangers and music. It’s a giant music festival in France to celebrate the first day of summer. Paris was the perfect place to roam around the streets filled with music of all genre ranging from the blues, electronic, orchestral, chorale, and rock. Unfortunately, I did get lost from the NBB crew because I was too absorbed listening to these drummers. Music has this universal constant where everyone can derive meaning from it, unlike foreign languages (Demorest et al, 2010).

 oh, the places I went!

You are probably thinking… great. My daughter is wandering around Paris staring at strange faces and listening to ten types of music. I understand your confusion, but I assure you that the tuition money is not going to waste. I’ve been trying to integrate all my sensory information, especially in seeing and listening. There seems to be relationship in background music and memory for facial expression (Wolozyn and Ewert 2012). This study aimed to investigate how happy or sad melodies affected the later recall of facial expression.

So, what exactly happened in the study? 48 undergraduates (32 females & 16 males) were recruited for the study. There were two sessions: study phase and test phase. From the beginning, they were told that there would be a memory test during the second session. During the study phase, they viewed a series 42 simple line drawings with accompanying background music (happy or sad or no music). The drawing was a child either laughing (happy) or frowning (sad) in various backgrounds. Using plain drawings was important since it eliminated other possible recognition cues, such as physical attractiveness or distinct facial features, that could have been used during the memory recall test. The background music clips (happy or sad), were from a standardized set of emotional music only consisting of a digital piano. In addition to the key (major or minor), the type of music differed in its tempo. Happy music was in the faster range (110-140 beats per minute, BPM) while the sad music fell in the slower range (66 – 110 BPM). Each illustration and its accompanying music was presented for 7 seconds to keep the presentation duration constant with two second intervals. From this arrangement, there were six stimulus types by varying the facial expression and the music type. (happy or sad + happy or sad or no music)

Summary of study phase conditions:

• a series of 42 simple drawings (happy or sad) for 7 seconds with 2 intervals
• with accompanying music in the background (happy or sad or no music)

happy or sad? the drawing used in the study

During the test phase, the 42 drawings were presented again with only the face blanked out, and there was no accompanying music. The participants had to recall if the blank face was happy or sad. If they could not remember the facial expression, they were told to guess.

Overall, the memory for faces was accurate, but the most intriguing part of the data is in the performance of the emotionally incongruent pairs (ex. happy face with sad music), which showed the lowest performace. The subjects recalled happy face as sad when it was accompanied by sad music and sad face as happy when accompanied by happy music. From this data and other similar studies, the researchers speculate that when recalling a scene, the emotional tone is set by stimulus from other senses (Eschrich, 2008 and Wolozyn and Ewert 2012). However, it’s important to note that the primary goal of the research was to study the memory retrieval of facial expression in various melodies and not on how background music influences one’s arousal or mood, although this may explain why the subjects were better at recalling the emotionally congruent pairs.

Interestingly, movies seem to be the realistic application behind this idea since they show many faces and situations paired with different music. Soundtracks have the ability to alter how the audience perceives the characters (Hoeckner et al, 2011). This idea of the emotional integration between face and music is equally represented in non-musicians and musicians, which suggests that this integration is not affected by individual musical training (Kamiyama et al., 2013). Additionally, patients with certain brain damages have hinted at some possible regions involving the association of music and facial expression. People with excision to the anteromedial temporal lobe showed impairment in their ability to recognized scary music and fearful faces (Gosselin et al, 2011).

All these different studies strongly suggest that there is a neural relationship between faces and music. This could partially explain why I have such happy thoughts when recalling fete de la musique. I know that in my inevitable nostalgia of the NBB Paris program, I will be seeing smiling faces with up beat music. So next time you meet someone, shine a beautiful smile and blast some happy tunes.

Last night Sehe, Kris decided to wander around for dinner and ended up finding a fantastic little pizza place called Café l’Éphémère.

Map of Café l’Éphémère

It was happy hour so we all got our own cocktail, mine being the pinkest drink I’ve ever ordered.

My Tequila Sunrise

The pizza was delicious and the escargot was definitely interesting, but my favorite part was seeing how the same amount of alcohol affected each of us in a different way.  My tequila sunrise did not affect me and Sehe’s French martini had little effect on her, but Kris on the other hand, was definitely feeling his vin chaud.  Why was it that even though we all drank the same amount, he was the one that was telling stories about “the good ol’ days” (he’s only 25…) and taking “artsy” pictures with the coaster and candle.  I decided to look it up when I got back.

Even though most research was centered on chronic consumption with reference to alcoholism, I did find a paper that was particularly interesting concerning alcohol sensitivity.  Often we say, “that person has a low tolerance” when they are easily affected by alcohol, however they are actually just more sensitive to alcohol’s effects .Tolerance is often defined as when the body becomes accustomed and less responsive to a substance (like alcohol) after repeated exposure(Webster, 2013).  You can have less of a response to alcohol without the repeated exposure.  Essentially, Kris was more sensitive to the effects of alcohol then Sehe and I.

The paper I found was Wargelius et. al, 2010 and it links 5-HIAA (a metabolite of serotonin) in the cerebrospinal fluid (CSF) and MAO-B with alcohol sensitivity in rhesus monkeys.  MAO-B is a mono amine oxidase, which breaks down monoamines (like serotonin).  It is often found in neurons and blood platelets. What was significant about this particular study was that it was one of the firsts to link MAO-B activity with sensitivity to the effects of alcohol.  (Wargelius et al., 2010).

Wargelius et al. had 78 rhesus monkeys receive an ethanol solution and after they were scored for their degree of intoxication (whether they fell, bumped a wall, or swayed).  They tested voluntary alcohol intake by having the animals participate in a procedure where they were able to choose between an ethanol solution, aspartame, and water for 5 days during a two week period.  They also took CSF and blood samples in order to test for 5-HIAA levels and platelet MAO-B activity.

They found that rhesus monkeys that had low platelet MAO-B activity also had low levels of 5-HIAA and were less sensitive to the effects of alcohol.  Interestingly, those with low platelet MAO-B activity also had more ethanol-induced aggression and higher voluntary alcohol intake.  These results combined with the knowledge that lower activity of MAO is related to behavior and psychiatric disorders, could suggest that individuals with low platelet MAO-B activity are more susceptible to alcoholism (Oreland, 2004; Wargelius et al., 2010).

I found this study very interesting because I really liked how it suggested a link between low MAO activity and high alcohol sensitivity.  In our NBB classes we are always talking about MAO activity in relation to various different psychological disorders.  However, since this one of the first papers to make this connection, it will be interesting to see if further research backs up their results.
