The amygdala - fear and stress response

Description:
Professor Bruce McEwen discusses how the amygdala is involved in processing fear and stress.
Transcript:
Starting with the amygdala, it is the brain area that’s involved in fear, fear learning, also to some extent in aggression. It’s also a brain structure that is involved in turning on the stress response, turning on the adrenaline, turning on the ACTH [adrenocorticotropic hormone] that causes cortisol secretion. It’s also an area that’s involved when you’re stressed and see something dangerous, like a snake walking in the woods. You freeze and then you later move back. It’s involved in all of these primary actions that are related to stress and self-defense.
