AP PSYCHOLOGY

Detailed explanation-1: -Amygdala is the integrative center for emotions, emotional behavior, and motivation. If the brain is turned upside down the end of the structure continuous with the hippocampus is called the uncus.

Detailed explanation-2: -The human amygdala plays a crucial role in processing affective information conveyed by sensory stimuli. Facial expressions of fear and anger, which both signal potential threat to an observer, result in significant increases in amygdala activity, even when the faces are unattended or presented briefly and masked.

Detailed explanation-3: -Face-selective neurons have been found in the amygdala, indicating that this region plays an important role in face recognition (Kosaka et al., 2003).

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.
