Summary
Selective heating of the spinal cord evoked panting in pigeons exposed to neutral ambient temperature. Cooling the spinal cord stopped panting which was elicited by peripheral heat (ambient temperature 38°C).
Electrophysiological recordings from ascending pathways of the spinal cord showed the existence of warm-sensitive neurons that were excited by heating the spinal cord. There was a nearly linear increase of impulse frequency in the range 35°–45°C spinal cord temperature.
Recordings in the preoptic area of the hypothalamus showed warm-responsive neurons that were excited by heating the spinal cord. There was generally a steep non-linear increase of impulse frequency in a temperature range where panting was observed (42°–45°C).
