Limbic System and the Amygdala
Captions available
The idea
The limbic system, including the amygdala and parts of the thalamus and hypothalamus, regulates emotion, fear, and motivation, and contributes to memory formation.
In practice
The amygdala is central to both feeling fear and recognizing fearful expressions on others' faces.
Where people slip
The limbic system is a functional grouping of connected structures, not one single anatomically bounded organ.
