Location And Structure Of The Amygdala
- The amygdala is a deep temporal-lobe structure named for its almond shape and sits just anterior to the hippocampus.
- It contains about 13 nuclei, indicating multiple specialized roles across emotion and memory processing.
Amygdala As A Limbic Hub
- The amygdala is a core component of the limbic system involved in emotion, behavior, and memory.
- It works alongside hippocampus, hypothalamus, and cingulate structures to integrate affective responses.
Amygdala's Role In Fear Is Complex
- The amygdala contributes to emotional processing and has been implicated in depression, anger, fear, and panic.
- Bilateral amygdala damage doesn't fully abolish fear, suggesting other circuits also generate fear responses.
