The amygdala has a primary role in the processing of memory, decision-making, and emotional responses (including fear, anxiety, and aggression). The amygdala was first identified and named by Karl Friedrich Burdach in 1822. [5]
The amygdala is a region of the brain primarily associated with emotional processes. It is located in the medial temporal lobe, just anterior to (in front of) the hippocampus. Similar to the hippocampus, the amygdala is a paired structure, with one located in each hemisphere of the brain.

Lakhan, MD, PhD, FAAN, a neurologist and chief medical officer of Click Therapeutics in New York, the amygdala is a “tiny little almond-shaped structure [that] is responsible for all that is emotion—largely fear, anger, pleasure, and anxiety.”
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.
Structure and Function. The amygdala is an almond-shaped structure that lies in the temporal lobe, lying just beneath the uncus. The amygdala is diverse and complex in structure and comprises approximately 13 nuclei. They further subdivide into extensive internuclear and intranuclear connections.
The amygdala is the part of the brain that’s most closely associated with fear, emotions, and motivation. Its name means “almond” because it is almond-shaped. If you see something that frightens...
