The effects of electrical stimulation of the central (CE) and basolateral (BL) amygdaloid nuclei on pancreatic exocrine secretion were tested in urethane-anesthetized rats. Electrical stimulation (0.1 mA, 1 ms, 40 Hz) of the CE significantly increased basal and hormone (secretin+cholecystokinin-8)-infused pancreatic exocrine secretion. These increases in pancreatic secretion were abolished by bilateral vagotomy. Electrical stimulation of the BL had no significant effect on basal and hormone-infused secretion. We conclude that the CE plays a stimulatory role in pancreatic exocrine secretion via the vagus nerve but the BL does not affect pancreatic secretion.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
