Describe the relationship between serotonin and aggression. How is the relationship affected by testosterone? By antidepressant drugs such as fluoxetine?
What will be an ideal response?
Serotonin is important because it plays a crucial role in the inhibition that the prefrontal cortex exerts on aggression. Studies have found low serotonin levels in a variety of groups showing impulsive aggression, and low binding of serotonin at receptors in the prefrontal cortex and amygdala is associated with higher aggressiveness; treatment with antidepressants that increase serotonin levels increases prefrontal activation and reduces aggression. Testosterone increases aggression.
