摘要：
In male rats anesthetized with urethane (600 mg/kg) and alpha-chloralose (60 mg/kg), extracellular recordings were made from tuberoinfundibular (TI) neurons in the paraventricular nucleus (PVN) identified by antidromic stimulation of the median eminence. Electrical stimulation of the gastric branches of the vagus nerve excited 26 (72%) of 36 TI neurons tested. I.v. (0.5-1 mug/rat) or i.p. (5 mug/rat) administration of cholecystokinin (CCK-8) excited 10 (63%) of 16 TI neurons tested. The excitatory responses induced by CCK-8 were abolished by bilateral cervical vagotomy. These results suggest that TI neurons in the PVN receive excitatory inputs from gastric afferents via vagus nerves.
