Function

• it is involved in modulation of neuroendocrine functions, visceral functions, & complex patterns of integrated behavior, including aggression, learning, feeding, & reproduction
• the amygdala is profusely interconnected with other brain structures, bidirectionally, especially the temporal lobe, striatum, hippocampus, hypothalamus, magnocellular neurons of the nucleus basalis, olfactory cortex, & autonomic centers in brain-stem & spinal cord.

• the amygdala is a heterogenous structure

Pathology

• pathologic changes in the amygdala are seen in neurodegenerative disorders, including:
  • Alzheimer's disease
  • Huntington's disease
  • neuronal ceroid lipofuscinosis
