Figure 7. Influence of celiac branch abdominal vagus nerve stimulation with or without anodal afferent block on regional colonic frequency power spectrum in anesthetized pigs.

Figure 7.

Frequency power spectrum analysis of the colonic motility in response to celiac branch vagus nerve stimulation (2 Hz, 5 mA) at pulse width of 4 ms alone or with anodal block at baseline (30 min), during the stimulation (15 min) and post stimulation (30 min) in proximal, transverse and distal (n=7–14) regions. Data are mean ± SEM, Wilcoxon paired or Mann-Whitney unpaired t tests, **p<0.01 vs baseline in respective groups.
