Corticosterone levels in response to insulin-induced hypoglycemia (1.5 U/kg), forced swim stress and the diurnal rhythm of CORT secretion are shown (left to right) from rats injected previously into the PVH with SAP control or DSAP. All blood samples were collected by remote sampling from a jugular catheter. For the swim stress test, rats were placed individually for 5 min in a bucket of water maintained at 370 C. Blood samples were collected at 30, 60, 90, 120, and 240 min after the start of the swim. DSAP severely impaired hypoglycemia-induced, but not stress-induced, CORT secretion and did not alter the diurnal rhythm of CORT secretion. Ritter, S., Watts, A. G., Dinh, T.
