Stimulatory effects of the central amygdaloid nucleus on pancreatic exocrine secretion in rats

Neurosci Lett. 1994 Mar 14;169(1-2):43-6. doi: 10.1016/0304-3940(94)90352-2.

Abstract

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.
