CEREBRART - Aggressive Brain
Aggression has become an important cultural problem worldwide presumably because of its deep seeded evolutionary roots in the neurochemical pathways and neuronal circuits of the human brain. Functional brain imaging studies in humans have revealed involvement of specific regions in the brain
in the expression of aggression and rage and chaotic neuronal circuits that play particularly important roles in the mechanism of aggression. Main general causes of aggression in people with neurodegenerative conditions are the frustration and anger associated with the person’s awareness of their predicament, and the structural brain damage and neurochemical alterations caused by damage and death of brain cells which automatically motivates aggression. In some psychopathic individuals the extremely heightened aggression was possibly the result of a selective decrease in brain serotonin turnover and a probable deficiency in the 5-HT1A or 5-HT1B receptor in brain regions regulating aggression which motivates those individuals to aggress. This CEREBRART work illustrates these ideas.
