Notably, chronic stress, and anxiety-related hijac, from chronic, unpredictable stress are thought to be more related to functioning within the bed nucleus of the stria terminalis BNST than the amygdala [ 18 ].
We are in exciting times, and it is hoped that continued functional dissection of amygdala-relevant pathways, across preclinical and clinical studies, will facilitate increasingly detailed clarification of how neural circuits create and modulate behavior. Your thinking, rational brain shuts down.
