There are two areas of the brain that are involved in aggression:
- the limbic system
- the amygdala
The limbic system is in the middle of the brain. It is called the emotional area of the brain because it is responsible for emotions such as fear and aggression.
The amygdala is a structure in the brain that recognises emotion. The amygdala also creates emotional responses. It is also responsible for producing aggression. In animal studies if the maygdala is removed then the animal becomes very calm and does not respond the threatening situations.
Human case studies also offer evidence. Charles Whitman (who killed 13 people) was found to have a tumour pressing in his amygdala
