Abstract
In urethan-chloralose anesthetized rats, units in the nucleus tractus solitarius (NTS) which antidromically responded to electrical stimulation of the parabrachial nucleus (PB) were investigated for their responses to hepatic-vagal afferent signals. Among 63 NTS units examined, 25 (40%) were excited, 17 (27%) inhibited and the remaining 21 (33%) unaffected by single shock electrical stimulation of the hepatic branch of the vagus nerve. Topical application of Na+ produced an increase in discharge rate of 9 units and a decrease in 5 units. Portal infusion of hypertonic saline produced an increase in discharge rate of 3 units and a decrease in 5 units. Furthermore, 3 units responded to both topical application of Na+ and portal infusion of hypertonic saline.
