In vivo electrophysiology of single afferent fibers in the musk shrews. A) An in vivo anesthetized preparation. B) Mechanical stimulation of the gastric antrum triggers two emetic episodes (esophageal shortening and closely spaced intratracheal pressure changes; retches). C) Activation of GI vagal afferents by gastric distension (1ml balloon). Signal-to-noise ratio of spikes; red marks show the single-unit with the red waveform from section B. D) Simultaneous recording of two (of 6) vagal fibers from one shrew that were sensitive to gastric distension. Unit waveforms are shown on the right.
