Spike frequency responses of excitatory gastric-related WDR neurons in SDH to GD and different MA stimulations. (a) Control group, without MA stimulation. (b) 0.5, (c) 1, (d) 2, and (e) 3 Hz MA stimulation, respectively. (f) Spike frequency changes evoked by different MA stimulations. In (a), (b), (c), (d), and (e), compared with baseline, and ; compared with GD, and ; compared with GD + MA, and ; compared with baseline after MA, and . In (f), compared with control, and ; compared with 0.5 Hz, and ; compared with 1 Hz, .
