Abstract
THE EXTERNAL GLOBUS PALLIDUS: BIDIRECTIONAL CONTROL OVER ANXIETY-RELATED BEHAVIOR MEDIATED BY CRFR1
Albert Lee Joseph Hunt, Jr., B.S.
Advisory Professor: Shane Cunha, Ph.D.
Corticotropin-releasing factor receptor 1 (CRFR1), the principle receptor responsible for the anxiogenic activity of the stress peptide CRF, is abundantly expressed in the external globus pallidus (GPe) raising the question whether activity in the GPe is altered in response to stress. I show that CRFR1 expressing neurons are of the “prototypic” subtype of GPe neurons. I provide evidence of novel circuits from CRF neurons in stress-responsive nuclei, including the paraventricular nucleus of the hypothalamus (PVN) and …
