an over stimulated amygdala could result in what kind of behaviors
Amygdala There are functional differences between the right and left amygdala. In one study, electrical stimulations of the right amygdala induced negative emotions, especially fear and sadness. In contrast, stimulation of the left amygdala was able to induce either pleasant (happiness) or unpleasant (fear, anxiety, sadness) emotions.[9] Other evidence suggests that the left amygdala plays a role in the brain's reward system.[10]
Prefrontal cortex Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex.[2] This brain region has been implicated in planning complex cognitive behavior, personality expression, decision making, and moderating social behavior.[3] The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals.[4]
