Properties of twitch-like contractile responses elicited by electrical stimulation of the vagus nerve in the rat esophagus. a Representative tracings of vagally mediated contractions in the intact and capsaicin-treated rat esophagi, respectively. Electrical stimulations were applied to the vagus nerve using single 80-V pulses (pulse duration 100 μs). Arrowhead Point of a single-pulse electrical stimulation, b latency, c time to peak, d duration. b–d Summary graphs of latency (ms; b), time to peak (ms; c) and duration (ms; d) of a vagally mediated twitch-like contraction. Data are presented at the mean [bars ± SD (error bars) (intact n = 4, capsaicin-treated n = 3)]
