Autism, the amygdala, and empathy




                This week’s film discussed the topic of disability, art therapy, and education of the disabled. When I hear about educating people with disabilities, I immediately want to know exactly what causes this disability and what effects it causes. I feel like it’s incredibly important to find the root cause of a disorder first, if you wish to educate someone with it. Autism is an interesting example to look into. In fact, the documentary from class discussed autism more than any other disorder.
                Autism is actually a very common disorder and practices in education haven’t really kept up with the research being completed by institutions. In fact, autism is estimated to be found in as many as one or two in a thousand children born today. Many of the issues surrounding autism education are about overcoming the impaired social interactions that are associated with the condition. I believe that in order to overcome these issues, we need to understand their root cause.
                When it comes to autism, we need to examine the structures in the brain that are causing these specific behaviors. Currently, there are many theories that postulate the neurological origin of the disorder. However, in my opinion, the most interesting path to pursue is a structure known for its role in emotion. Currently, there are two camps of thought. The entire debate centers around the role of the amygdala. The amygdala is a small almond shaped clusters of nuclei located in the limbic system. Often times, the limbic system and its surrounding structures are referred to as the “old” or “lizard” brain because of its primitive origins.  It is responsible for a number of neural processes. The amygdala is the center of emotion based learning. When we learn to fear or become anxious of something, we learn to avoid it. This learning is because of the amygdala. However, because of this, over activation of the amygdala seems to be responsible for panic or anxiety attacks in humans.

                How does the amygdala play a role in autism? Bauman and Kemper in 1985 originally noticed that in the brains of post mortem autistic brains, there was severe abnormality in the limbic system, specifically in the amygdala.  Many neuroscientists have postulated that the amygdala is vital in social interactions. Some researchers claim that over-activation of the amygdala would is a cause (or potentially symptom) of autism. They argue that over activation in the limbic system would explain the extreme anxiety associated with social interactions. However, there is an alternative explanation proposed by other theorists stating that it is under-activation of the amygdala that would explain the behavior of social withdrawal and a limited understanding of proper social cues and reactions.
                Assuming that the amygdala is the source of these issues (which some researchers are beginning to believe that the amygdala is a victim of a much larger disorder, however the research is still coming in on that theory), how can we properly begin to instruct individuals with autism? There is a theory that understanding that social interactions may be over stimulating the amygdala is the very first step to fixing the problem. If these individuals are not naturally inclined to understand complex social interaction, and that it may cause something like anxiety attacks, it is probably best to instruct these individuals on proper emotional responses.
                The Autism Research Center, located at the University of Cambridge, has developed a program that can potentially assist children with autism.  This program focuses around fifteen fifteen-minute long CGI episodes. These shows use everyday vehicles such as trams, trains, and other rail based transportation to teach children with autism emotion recognition skills. These rail cars are called The Transporters. Each of the episodes focuses on a particular emotion in context. The programs use these rail cars with oversized and over emoted human faces on the front to demonstrate each emotion. The theory behind the rail based vehicles as characters is that many children with autism prefer motions that are structured and repetitive. These trains can only move on their tracks, therefore they are unable to make spontaneous movements.
                This program sounds like many other educational series aimed at children, however this particular series of exercises has been clinically shown to improve emotion recognition in children with autism. This research is backed by the Autism Research Center and more specifically, Dr. Simon Baron Cohen. Dr. Cohen is a well-respected figure in the autism research field.  The fact that this program has actually shown a marked improvement in emotion recognition is absolutely amazing. This could be an amazing step towards helping to integrate children with autism into the classroom. The video below introduces Dr. Cohen and explains the program.
                Now that I have rambled about the limbic system and rail cars with faces, the question still remains as to how this is going to assist educators. As I said earlier, many of the issues that educators face when working with children with autism is their inability to understand emotion. Now, considering that this short program series (fifteen minutes a day for four weeks) has shown considerable help in allowing these children to understand emotion, this seems like an absolute no brainer. More research based on emotion education needs to be completed. We should be actively searching for a way to assist educationally disabled children become as well rounded as their non-disabled peers.
                What does the amygdala have to do with autism education? I believe that now that we can pinpoint neural structures responsible for these behaviors, we can also begin to assess how to treat children with autism (be it with therapy, biofeedback, or unfortunately medication). However, I believe that this information has a much more practical application. If educators understand that their students are having reactions that are akin to panic attacks, that can help them begin to empathize with the experience that children with autism go through. We often, mistakenly, assume that because children with disabilities are different than us, we cannot possibly understand what kinds of emotions or thoughts that they are having. However, I believe that neurological research in this field can help everyone empathize with educationally disabled individuals, rather than pity them.
