The ethics of brain disorder.

An argument can be made that who you are and what you experience are constructs of your brain. What you see and hear and taste and smell and feel, while coming from your sensory organs, are processed, and "interpreted" in the brain. They are merely information that is processed by your brain and result in what could perhaps be called an arbitrary reality. And your brain can be fooled: optical illusions and tactile illusions are just two ways for you to demonstrate that your brain creates your reality.

So if you take the case, even if just for a moment, that your brain creates your reality - you can start to delve into the possibility that everything could (should?) be questioned. Your view of yourself, for sure - are you REALLY that way? Definitely your view of others and life should be questioned. What about your past? You already have several examples of how things didn't really go down as you remember. And it is becoming increasingly obvious that eye witness testimony is flawed, sometimes fatally. And what about your future? That you even think that your future exists (good or bad) demonstrates the wondrous ability of our brain to fabricate a reality.

One pitfall we all have (yes, even you) is thinking that you can distinguish what is real from what isn't. Have you ever awoken from a dream where you and your significant fought? And you were still upset late into the day with said person until you realized that the reason for your ire couldn't possibly be real - I mean, when have you ever had a pet dragon that they hated, much less secretly barbecued for your friends?

So where do ethics come in? One notion that deserves scrutiny is that we are fundamentally good and that when we do something bad, we did it on purpose. You might consider that our entire justice (punishment?) system is based on this notion. That we have an insanity defense is proof that the accepted perception is that 'normally' we can distinguish right from wrong, unless something is off with our brain.

If you are up for wading into the contradictions that may be starting to tingle your spidey-sense, I recommend reading David Eagleman's book - Incognito. In this book, Eagleman relates a story in which a man's penchant for child pornography is solely the result of his brain tumor. That a complex behavior could be the result of brain disfunction is astounding, and begs further inquiry into the behavioral effects of brain abnormality. Especially when you consider that the brain can be trained to do anything. ANYTHING. For further reading on the amazing ability of the brain to learn and relearn (even seemingly impossible) things, check out The Brain that Changes Itself by Norman Doidge.

If the brain creates a reality that includes how we interact with the world - is our prison system really the best way to habilitate a human being? This is a question that is so mired in "yeah, buts..." that it is vastly difficult to hold a reasonable discourse on it. But we can (should?) start to question how we think about people who have committed heinous crimes. Like Aaron Hernandez.

Aaron committed suicide at 27 years of age while he was in jail for murder, and he had C.T.E., Chronic traumatic encephalopathy - a persistent or long-standing neurological (brain) disorder induced by trauma. Hernandez was an embarrassment to his former team and they refunded thousands of fans who had purchased his jersey. The hidden communication behind all this could be interpreted as "We didn't realize how bad a human being this individual was and we are sorry".

How does one get C.T.E. and did this disease play a role in his criminal behavior? C.T.E. is caused by repeated trauma to the head, as is common amongst veterans or athletes such as boxers, WWE fighters and NFL players.

Much of what we know about the brain is through studies that reported functional or behavioral deficits after localized trauma. We know that trauma to the fore-brain can impact higher order functions such as decision-making and social cognition. People with damage to the amygdala are more likely to make decisions that do not take emotional processing into account.

Since we know that damage to the brain can result in personality changes that can have dire consequences, shouldn't we be putting attention on how best to eliminate those factors that can induce the worst kind of behavior in people?

Wait, what? Did I just say out loud that certain activities (like perhaps tackle football) may actually result in human beings committing heinous acts? There is a lot about the brain that we don't know, yet when there is compelling evidence that some activity has horrible consequences (don't get me started on global warming) shouldn't we take action to eliminate the risk?

I love football. Any ideas on how to make it safer?
