Stimulated release of endogenous OX produces OXR1 dependent CeA neuron depolarization. (A) Representative PeF (20×) and CeA (40×) images demonstrate DREADD-mCitrine-positive cell bodies and fibers of cells expressing prepro-OX-DREADD-mCitrine virus. Boxed area is enlarged to show individual mCitrine-positive PeF neurons. (B) Schematic of regions that were imaged (-2.40 mm bregma for CeA, -2.80 mm bregma for PeF). (C) Summary data of Clozapine-N-oxide (CNO), DREADD agonist, effects for the indicated conditions (n = 9–13). (D) Representative traces from CNO treated neurons. CNO stimulated depolarization in animals expressing PeF-targeted DREADD virus except when OXR1 was antagonized by C 56. Solid bars under traces indicate perfusion of CNO. Data are means ± SEM, symbols indicate significance by Sidak’s post hoc test, p < 0.05, between subjects, # within subjects.
