[The activity of the motor units of the feline esophagus under cooling]
Abstract:
The background activity of the oesophagus motor units (MUs) was found to depend on respiration and to be facilitated in cooling. The MUs patterns of discharges involved a phasic activity and a tonic one. The firing rate of the MUs increased during expiration. A negative correlation was found between the phasic MUs firing rate and the skin temperature.
