The amygdala is primarily involved in emotional processing and response, making it central to how we experience and react to emotions such as fear, pleasure, and anger. It plays a critical role in the formation of emotional memories and helps in assessing emotional significance in various stimuli. When a person encounters a potentially threatening situation, the amygdala becomes activated, triggering the body's fight-or-flight response.

The amygdala's involvement in emotional reactions extends to evaluating social signals, such as facial expressions, contributing to interpersonal interactions and emotional intelligence. For example, it helps individuals recognize fear in others, enhancing their ability to react appropriately in social situations. Given these functions, understanding the role of the amygdala is essential in psychology, as it highlights the connection between emotions and behavior.
