Summary

  1. 1.

    The temperature sensitivity of thermoreceptors and slowly adapting mechanoreceptors in the trigeminal area of pigeons were tested while recording from all three main branches of the trigeminal nerve.

  2. 2.

    Warm receptors were excited by warming and totally inhibited by cooling. During rewarming no overshooting excitation occurred. The impulse frequency increased with increasing temperature; at low temperature the receptors fired in bursts.

  3. 3.

    A special “warm-sensitive” receptor with a regular discharge rate at high skin temperature was totally inhibited by cooling and restored its initial frequency after rewarming without any overshoot. The impulse frequency did not increase with increasing temperature but was constant above a critical skin temperature.

  4. 4.

    Most of the slowly adapting mechanoreceptors had a very regular, rather high impulse frequency (20–50 imp./sec) at constant mechanical stimulus. The impulse frequency decreased during cooling without an excitatory overshoot and increased during warming without an inhibition.

  5. 5.

    Only few slowly adapting mechanoreceptors were excited by cooling and inhibited by warming, a behaviour which is reported for all temperature-sensitive mammalian mechanoreceptors.
