Sex hormones act in the limbic system and in the raphe nucleus, source of the neurotransmitter serotonin . The fight or flight response is in here. Instead, a teen's thinking is driven more by the amygdala - two small almond-shaped groups of cells found down near the base of the brain's left and right temporal lobes. Both of these structures are involved in the body's response to fear and danger. "The amygdala is a unique brain structure in that it grows dramatically during adolescence, longer than other brain regions, as we become more socially and emotionally mature," said Cynthia Schumann, associate professor in the Department of Psychiatry and Behavioral Sciences at the UC Davis MIND Institute and senior … There is considerable growth within the first few years of structural development in both male and female amygdalae. When you think of the amygdala, you should think of one word. Our brain is made up of cells and every ability we have is the product of those cells. The adolescent brain predominantly processes information using the amygdala - the emotional part of the brain. In Teenage Brain . One of the major nuclei in the brain is called the amygdala. In fact, recent research has found that adult and teen brains work differently.
