Changes in circulating levels of plasma corticosterone (A) and ACTH (B) induced by microdialysis-mediated administration of VP antagonist in the PVN/DMH area at CT6 (Ringer’s, ▪, n = 11; VP antagonist, •, n = 10) or exposure to a new environment (New cage, ▵, n = 7).Letters indicate significant differences compared with Ringer’s (a) and VP antagonist (b) according to Student–Newman–Keuls (p < 0.05).
