Summary

The discharges in single afferent fibres of the ophthalmic nerve innervating the upper beak in two kinds of geese (Anser anser andAnser albifrons) were studied during manual and controlled mechanical stimulation. Three types of unit were recorded.

  1. 1)

    Rapidly adapting units deriving from Grandry corpuscles had receptive fields of up to 12 mm in diameter which overlapped or enclosed each other in certain beak skin areas. They responded quantitatively to the velocity of a displacement and there was a wide range of variability in the threshold sensitivity of minimal required displacements and the sensitivity to changes in the stimulus velocity. Grandry units were not spontaneously active and lacked an amplitude component in the response to trapezoidal stimuli.

  2. 2)

    Rapidly adapting units, almost certainly deriving from Herbst corpuscles, required high movement velocities to be activated and appeared to respond only to the acceleration or deceleration phase of a movement. Consequently, Herbst units were excited optimally by vibratory stimuli between 40 and 1500 cycles/sec. A consistent relationship between the velocity of a trapezoidal stimulus and the frequency of discharge in Herbst units could not be demonstrated. The units were not spontaneously active and were located in receptive fields which were often small but could occasionally cover the whole beak.

  3. 3)

    Slowly adapting units deriving from a still unidentified morphological structure were found to originate exclusively in the horny tip of the bill. These units were often spontaneously active and two kinds of slowly adapting discharge with a regular and an irregular discharge were observed. Trapezoidal stimuli elicited both dynamic and static responses which were proportional to the velocity of the movement and its displacement amplitude, respectively. Larger displacements were followed by silent periods which increased in duration with increasing displacement amplitudes. The time course of the adaptation of a response to a constant displacement showed several time constants. The discharge frequency increased on cooling and decreased on warming the receptive field.

  4. 4)

    The experimental findings are discussed with respect to morphological and other physiological results. A model of the operating principle in tactile sensory mechanisms in the goose is proposed, based on the evidence of the morphological and physiological organization of mechanoreceptors and primary afferent units in the beak skin of geese.
