RESUMO

1. The effects of continuous preganglionic stimulation of the chorda tympani at 2 Hz for 10 min were compared with those of stimulation at 20 Hz in 1 sec bursts at 10 sec intervals for the same period in cats treated with atropine (0·5 mg/kg). Both the fall in mean submaxillary vascular resistance (s.v.r.) and the rise in mean vasoactive intestinal peptide (VIP) output from the gland were increased significantly (P < 0·01; P < 0·02) when the same total number of impulses were delivered in the form of bursts at the higher frequency.
