From: Selective stimulation of the ferret abdominal vagus nerve with multi-contact nerve cuff electrodes
Low amplitude abdominal VNS selectively changes GI myoelectric activity but not breathing or heart rate. (a,e,i) In three animals, stimulation (orange) through one cuff pair caused a substantial change in normogastric power as compared to baseline (blue), while stimulation through the other cuff pair had a smaller or no effect. (b,f,j) Waterfall plots show signal power in frequencies between 6 and 15 CPM over time. Blue lines are pre-stimulation baseline and orange lines are during stimulation. (c,g,k) Stimulation through either cuff pair had little or no effect on breathing rate. (d,h,l) Stimulation through either cuff pair had little or no effect on heart rate.
