Central Nucleus
The amygdala is composed of distinct subregions with specialized roles. One key region has dense connections with various sensory areas of the brain, allowing it to assign emotional significance to incoming information and memories. Another key region has extensive connections to the hypothalamus and brainstem, which are responsible for regulating autonomic physiological responses. A person hiking in the woods suddenly encounters a bear. They experience an immediate surge in heart rate and breathing, and later form a powerful, lasting memory of the fear associated with that specific trail. Which statement best analyzes the roles of these two amygdala regions in this experience?
