Typical examples of the firing patterns of E neurons. a E neuron with descending axons to the T13. Firing frequencies of E neurons increased during the repetitive rise of rectum pressure. b E neuron with descending axons in the S3. Firing frequencies of E neurons decreased during the repetitive rise of rectum pressure. IF instantaneous frequency, Rectum press rectum pressure, Abd med br abdominal medial branch, Phr nerve Phrenic nerve, Press. “off” and Press. “on” rectum pressure “off” and “on”
