Document Summary
Emotions we experience include a biological response. The brain regions are connected to each other in such a way that the ring associated with one stage of an emotional response will in uence the patterns of ring associated with subsequent stages of the response. Your emotional system allows for later stages to provide feedback to earlier stages. The purpose of this initial brain activity is to tag or highlight that stimulus so that it receives extra processing by brain structures at later stages of perception. A critical area involved in this process is the amygdala, a group of nuclei in the medial portion of the temporal lobes in each hemisphere of the brain. Amygdala = res when we perceive stimuli that are emotionally arousing and is especially sensitive to dear-relevant images and sounds. It is the amygdala projections to other brain structures that lead to the observable behaviours that we think of as being emotional responses.
