An inappropriate aggressive response to a perceived threat
4 of 13
What is Serotonin?
A Neurotransmitter
5 of 13
What happens if levels of Serotonin are too low?
Communication between the Amygdala and Pre-Frontal Lobes weaker. This makes it more difficult for the Pre-Frontal Cortex to control emotional responses to anger, that come from the Amygdala
6 of 13
What role does Testosterone have?
Increases the activity in the Limbic System. Changes in Testosterone levels influences aggressive behaviour, by increasing Amygdala reactivity during the process of a threat

What animal research is there to support the role of the Limbic System in aggression ?
Bauman - Destruction of the Amygdala in monkeys lead to them loosing their dominant position in the group
8 of 13
What human research is there to support the role of the Limbic System in aggression?
Gospic - Used brain scans of participants who had played an aggressive game. aggressive play was associated with a fast and heightened response in the Amygdala
9 of 13
What animal research is there to support the role of Serotonin in aggression?

What human research is there to support the role of Serotonin in aggression?
Virkkunen - Tested the Cerebrospinal Fluid in violent impulsive offenders and found that they had much lower levels of Serotonin than normal
