The amygdaloid body is also known as the amygdaloid nucleus. This is an oval structure located in the temporal lobe. 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 made 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 amygdaloid body is also known as the amygdale, nucleus amygdalae, porpus amygdalolieum, amygdaloid complex, and amygdaloid nucleus. The amygdala is an important part of the brain, which assists in responses of fear and pleasure. The size of the amygdaloid body is known to correlate with how aggressive a species is. If a male is castrated, the amygdaloid body can shrink up to 30 percent. The abnormal working of the amygdaloid body can lead to developmental problems, depression, anxiety, and autism.
