1. Emotion regulation: The amygdala is one of the main regulation centers of emotions. It is connected with many neural pathways such as olfactory system, visual system and auditory system, and can receive sensory information from the outside and the inside. When we are faced with threats, fears or pleasant stimuli, the amygdala will participate in the corresponding emotional response, such as fear, pleasure or excitement.

2. Memory storage and emotional correlation: The amygdala is interconnected with hippocampus and frontal lobe, and participates in memory storage and retrieval. Especially the memory related to emotion, such as traumatic memory or emotional memory, the amygdala plays a key role in it. It can affect our memory of specific emotional events by adjusting the strengthening or weakening of memory.

3. Social behavior: The amygdala is also involved in the regulation of social behavior. It can recognize and interpret other people's nonverbal information such as facial expressions, voices and body language, and communicate with emotion-related brain regions. This makes the amygdala very important for understanding the emotional state of others and producing corresponding social reactions.
