[Tactile receptor reactions during discontinuous and sinusoidal hair oscillations]

"On"--"off" response characteristics of the afferent neurons of the sixth abdominal ganglion of the crayfish are described. They are developed in response to the stepped and sinusoidal oscillations of a receptive hair. A conclusion is made that moments of possible impulse arising in neuron response are defined by the simple input influence. Reaction variability under the action of one and the same stimulus appears due to a change of the impulse arising probability in these moments, but not because of the changes in time moments.
