[Responses of neurons in the sensomotor cortex of the cat to auditory stimuli of different duration before and after elaboration of a conditioned reflex].

Evoked activity of cells in the sensomotor cortex to sounds of various duration (0.001, 0.1, 1 s) before and after conditioning was studied in experiments with cats. The highest percentage of evoked responses, intensity and duration of neuronal reactions were observed during the long sound stimulation (1 s). A conclusion is made that the long sound was most effective for conditioning.
