Document Summary

Emotional behaviour are complex and involve a number of different components or stages. Each of these stages use a distinct set of brain regions. Brain regions connected to each other that the firing associated with one stage of an emotional response will influence the patterns of firing associated with subsequent stages of that response. Emotional system also allows for later stages to provide feedback to earlier stages. This allows to modify emotional response as you learn more about the situation. Initial response human brain shows emotion-dependent response within. 150 ms of see or hearing potential threat. This is to tag or highlight the stimulus so that it receives extra processing by brain structures at later stages of perception. Critical brain area in this process is amygdala- a group of nuclei in the medial portion (near the middle) of the temporal lobes in each hemisphere of the brain.
