Cross-correlations between E neuron and Abd nerve. a Expiratory (E) neuron discharges and integrated abdominal (Abd) nerve discharges. b cross-correlations between IF of E neuron discharges and integrated Abd nerve discharges. Cross-correlations during the rectum pressure “off” (Left) and “on” (Right). The peak correlation shows a high value during the rectum pressure “off” and a lower value during the rectum pressure “on”
