AP PSYCHOLOGY

Detailed explanation-1: -The fear response starts in a region of the brain called the amygdala. This almond-shaped set of nuclei in the temporal lobe of the brain is dedicated to detecting the emotional salience of the stimuli – how much something stands out to us.

Detailed explanation-2: -The central nucleus of the amygdala also produces conscious perception of emotion primarily through the ventral amygdalofugal output pathway to the anterior cingulate cortex, orbitofrontal cortex, and prefrontal cortex. Stimulation of the amygdala causes intense emotion, such as aggression or fear.

Detailed explanation-3: -amygdala, region of the brain primarily associated with emotional processes. The name amygdala is derived from the Greek word amygdale, meaning “almond, ” owing to the structure’s almondlike shape. The amygdala is located in the medial temporal lobe, just anterior to (in front of) the hippocampus.

Detailed explanation-4: -The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
