Abstract

The amygdala is a crucial brain region responsible for emotional processing and fear conditioning and learning. The major classes of neuroreceptors and pathways present in this region are significantly engaged in such functions that extend to memory associations, cognition, appraisal and responsiveness to emotional and fearful stimuli. There is evidence of a rich integration of neurofunctions and connection with the rest of the human physiological system. Gender differences in amygdala reactivity to stimuli are also discussed to aid understanding of external factors that may play a role in causation of such differences.
