Anatomy
The amygdala is the part of the brain primarily involved in emotion, memory, and the fight-or-flight response. It is one of two almond-shaped cell clusters located near the base of the brain. Together, the amygdalae (plural), also known as the amygdaloid complex, is an important part of the limbic system.

Functions
Amygdala is your center of emotions. Studies suggest electrical stimulations of the right amygdala induces negative emotions, especially fear and sadness. In contrast, stimulation of the left amygdala induces either pleasant (happiness) or unpleasant (fear, anxiety, sadness) emotions.
In complex vertebrates, including humans, the amygdalae perform primary roles in the formation and storage of memories associated with emotional events.
Neuropsychological correlates of amygdala: Sexual Orientation: Recent studies have suggested possible correlations with sexual orientation
Social interaction: Amygdala volume correlates positively with both the size and the complexity of social networks.
Aggression: Animal studies have shown that stimulating the amygdala appears to increase both sexual and aggressive behavior.
Fear: People with damaged amygdala feel no fear.
Anxiety, Post-traumatic stress disorder and bipolar disorder also have associations with amygdala.
