amygdala
Noun: - An almond-shaped cluster of neurons located deep within the brain's temporal lobe. It is a key component of the limbic system and is critically involved in processing emotions, especially fear and pleasure, and in forming emotional memories.
The word "amygdala" is used primarily in scientific, medical, and psychological contexts to refer to this specific brain structure. - The amygdala is activated when a person experiences fear. - Research focuses on the amygdala's role in anxiety disorders. - The stimulus was processed by the amygdala before the conscious mind was aware of it.
- "Amygdala hijack": A term popularized by psychologist Daniel Goleman describing a situation where the amygdala triggers an immediate, overwhelming emotional response (like fear or anger) that bypasses the brain's rational, prefrontal cortex.

- Amygdaloid body: A direct anatomical synonym.
