Figure 4.

Changes in plasma glucose and plasma corticosterone concentrations as a result of VP antagonist administration in either the PVN (circles) or DMH (triangles). Despite the comparable responses of plasma corticosterone (p = 0.621 and p = 0.047 for group and group × sample effects, respectively), the effects of the VP antagonist on plasma glucose are clearly dissimilar (p = 0.011 and p = 0.005 for effects of group and group × sample, respectively). Closed symbols represent the effect of the VP antagonist, and open symbols represent results of the control experiment. ^p < 0.1, ^**,^^^,++p < 0.05, ^***,^^^p < 0.01. The asterisks indicate the results of the unpaired (i.e., PVN vs DMH) Student's t tests. ^ and ⁺ indicate the results of paired (i.e., experimental day vs control day) Student's t tests for the PVN (^) and DMH (⁺), respectively.
