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

Figure 5

Effect of EA at PC6 on gastric motility after the microinjection of different drugs into the dorsal nucleus of the vagus nerve. (a) Artificial cerebrospinal fluid, L-glutamic acid, and GABA were microinjected to the dorsal nucleus of the vagus nerve, and the wave patterns of gastric motility during EA at PC6 were recorded. (b) Increase in intragastric pressure induced by EA at PC6 after the microinjection of artificial cerebrospinal fluid, L-Glu, and GABA into the dorsal nucleus of the vagus nerve. P < 0.05, compared with the artificial cerebrospinal fluid group (n = 8).
