EA at PC6 Promotes Gastric Motility: Role of Brainstem Vagovagal Neurocircuits

Figure 4

Increase/decrease in gastric motility after the microinjection of different drugs into the dorsal nucleus of the vagus nerve. (a) Wave patterns of gastric motility before and after the injection of artificial cerebrospinal fluid, L-Glu, and GABA into the dorsal nucleus of the vagus nerve. (b) Increase/decrease in gastric motility after the microinjection of artificial cerebrospinal fluid, L-Glu, and GABA into the dorsal nucleus of the vagus nerve. Percentage reduction, P < 0.05, compared with the artificial cerebrospinal fluid group (n = 8). (c) The location of microinjection to DMV.
