|chemicals||adrenaline, dopamine, serotonin|
The vibrant colors of the murals in Clarion Alley in San Francisco awaken my senses. The twilight is perfect for capturing the mood via photographs.
I finish planning a composition and am about to click when a man on a bike rides by and snatches the camera from my hand. For a few split seconds, I do not comprehend or accept what has just happened. Then I start to scream: He stole my camera! He stole my camera!
I feel violated. I have several months of photographs in that camera. My camera!
I run after him, screaming, as he turns right onto Mission Street. I realize that I have lost my photos and will not be getting them back but I am unable to accept this fact. I continue to scream. Then a strange and unexpected series of events occur.
The man who has stolen my camera comes back into the alley on foot. He holds up the camera as if he is going to give it back to me. I reach for it, unsure as to what is going on. He runs with the camera tightly held within his large hand. What happened to his bicycle, I wonder but I do not have time to consider this. He is running now in the opposite direction from Mission and towards Valencia Street. He is running towards the Mission Police Station! I doubt that he realizes this, however.
I start screaming at the top of my lungs and run after him. I am not saying anything this time. I am simply making a deep guttural sound, primitive language-independent screams of distress.
A policeman on a bike rides by me and asks what happened. He is headed from Mission to Valencia, the same direction as the thief. I tell him and he rides after the thief, who has already disappeared around the corner on Valencia. Another policeman on a bike also chases after the thief. I wonder if this might be why the thief has abandoned his bike, to perhaps find a route that does not allow a bike passage. Or, perhaps his bike is stolen also.
Then I hear sirens.
I slow down and start walking instead of running. I am out of breath and feeling calmer. A group of people walk towards me “You are lucky, they got him,” one of them says.
Why do I react with so much aggression and without any consideration for my safety?
Surprise or fear can trigger an adrenaline rush. The quantity of the adrenaline released and thus the degree of reaction is determined by chemical factors. A low quantity of the “happy” neurotransmitters dopamine and serotonin in the brain triggers a higher degree of adrenaline production. In other words, the less happy the brain, the higher the level of adrenaline it produces.
When the thief ripped the camera from my hand, my adrenaline level probably shot up. The level of adrenaline might have been exacerbated even further by the fact that I was in an unhappy mood. I had left my apartment a few hours ago in an angry mood because I was upset with my boyfriend. This would have resulted in a depletion of dopamine and serotonin.
In a different state of mind, would I have screamed less and potentially let the thief get away? Or would I have not made the primitive guttural sounds that, in retrospect, seem to be an over-reaction to the loss of some photos, as precious as they might have been.
Low dopamine and serotonin and high adrenaline do not activate a response but only contribute to the activation. The response is activated in the limbic system specifically in the amygdala. The amygdala is one of the major organs responsible for the perception of threat and for triggering an emotional response. It can hijack the potentially rational responses from other parts of the brain and cause irrational reactions. In my case, I did not consider my own safety because I was furious that my personal space and property had been violated.
Later that day, when I am in the Police Station talking into a tape recorder and going through the story of what has happened, the police inspector asks me if I want to press charges.
“It’s wrong to steal and he should be punished. But he must have been really desperate to want to steal a camera,” my thoughts tumble out of my mouth. I decide not to press charges. Technically, it is not my decision because the district attorney will press charges anyway because the man was arrested. I did not know this at the time, however, and despite my conflict, I made a decision to not punish the thief any more than he had already been punished.
Perhaps I was being kinder because the dopamine and serotonin levels in my brain had surged back up when I found out that justice had been done and that I would get my camera back. Also, my boyfriend came to the police station and held my hand and kept me company while the inspector was talking to me. His presence might have contributed to the raised levels of the “feel good” hormones.
This is all hypothetical, of course, based on my knowledge of neuroscience and research on the neuropathy of anger. I would have had to be hooked up to an fMRI (functional magnetic resonance imager) to prove my hypothesis about the actions of the amygdala and the levels of adrenaline, serotonin, and dopamine in my brain. Nonetheless, it is fun to try to guess the biological triggers for my actions when confronted with a “fight or flight” situation.
