[Several characteristics of the impulse reactions of crayfish receptor neurons to stimuli of different intensity].
Properties of the receptor cells responses in n. telsoni ventralis to the change in the direction, velocity and angle of displacement of the uropod hairs were studied in acute experiments with the crayfish Astacus leptodactylus. It is shown that the receptor neurons are characterized by an inverse relation between the latent period and the velocity of hairs displacement and by impulse frequency proportional to this velocity. The selective sensibility of the various receptor neurons to the direction and change of angular displacement of a hair was found. Certain zones of the angle of displacement of the uropod cells characterized by evoked maximum receptor cells responses are distinguished.
