Electroacupuncture at ST36 modulates gastric motility via vagovagal and sympathetic reflexes in rats

Figure 5 Gastric motility changes after dorsal motor nucleus of the vagus nerve microinjection of different amino acids. A: Percentage change of gastric motility after microinjection of artificial cerebrospinal fluid, glutamic acid, or γ-aminobutyric acid (GABA) into dorsal motor nucleus of the vagus nerve (DMV) (GABA-I is the inhibitory effect group, and GABA-E is the excitatory effect group); ^aP < 0.05 compared with the control group; B: Waveform of gastric movement changes after microinjection of artificial cerebrospinal fluid, glutamic acid, and GABA into the DMV. GABA: γ-aminobutyric acid; DMV: Dorsal motor nucleus of the vagus nerve; L-Glu: Glutamate.
