Phelps, E. A. and Anderson, A. K. (1997). The amygdala is a brain structure that is essential for decoding emotions, and in particular stimuli that are threatening to the organism. The amygdala and hippocampus are two parts of the brain responsible for the processing of memories. Acting in conjunction with other parts of the limbic system, such as the hippocampus, this part of the brain helps regulate and encode emotional memories..

The lateral nuclei receives the majority of sensory information, which arrives directly from the temporal lobe structures, including the hippocampus and primary auditory cortex. Amygdala Amygdala has been shown to coordinate with prefrontal cortex during the encoding and experience of emotion-based learning, and to coordinate with memory structures (i.e. The amygdala is an unconscious processor that receives incoming sensory information and then processes this information for an emotional response.
