Parabrachial CGRP neurons modulate active defensive behavior under a naturalistic threat
Recent studies suggest that calcitonin gene-related peptide (CGRP) neurons in the parabrachial nucleus (PBN) represent aversive information and signal a general alarm to the forebrain.If CGRP neurons serve as a true general alarm, their activation would modulate both passive and active defensive behaviors depending on the magnitude and context of t
