Whose Brain Is It?
by Leena Prasad
Lou has lost weight. He has dark circles under his eyes from insufficient sleep but does not look tired and appears to be happy. He is focused at work and getting a lot done. He is also spending more time on his guitar and writing a new song almost every week.
A friend that Lou had not seen for a while wonders if Lou has slipped back into his cocaine habit. The dopamine level in Lou’s brain is consistently high these days. Dopamine is a neurotransmitter produced by the brain and plays a starring role within the pleasure circuits of the human mind. Cocaine increases the level of dopamine in the brain resulting in feelings of happiness, improved focus, increased energy as well as lower needs for food and sleep.
Lou’s mother, who sees him sporadically, worries that he has developed a disorder because he is displaying new behavior patterns. He spends a lot of time in his childhood room ordering and re-ordering things. He either taps his foot constantly when sitting down or paces back and forth in the living room when talking to her. She has not said anything because he also seems to be happier than usual and she wonders if the changes might be the effect of his recent job promotion.
His mother reads a lot of popular psychology articles and thinks that he might have a mild case of obsessive-compulsive disorder (OCD).
Can you guess what is going on in Lou’s brain?
Lou is not taking cocaine.
