Amygdaloid body

Medically reviewed by Healthline Medical Team on January 7, 2015

The amygdaloid body is also known as the amygdaloid nucleus. This is an oval structure located within the temporal lobe of the human brain. The structure is a small part of the brain and is closely associated with the hypothalamus, cingulated gyrus, and hippocampus.

Smelling, motivation, and emotional responses are facilitated by the olfactory and limbic systems, which are partially made up of the amygdaloid body. The amygdaloid body was named for its almond shape. Amydale is the Greek word for “almond,” and eidos is the Greek word for “like.”

The amygdala is an important part of the brain, which assists in responses of fear and pleasure. The abnormal working of the amygdaloid body can lead to various clinical conditions including developmental delay, depression, anxiety, and autism.
