Question

Epinephrine activates brainstem nuclei that produce norepinephrine. It does not cross the blood-brain barrier to directly influence the amygdala, and it does not disrupt the release of norepinephrine by brainstem nuclei. While the amygdala is involved in fear conditioning and the basolateral nucleus plays a role in this, there is no evidence that epinephrine is released by the basolateral nucleus specifically in response to foot shock.
