[Spatial frequency characteristics of the receptive fields of neurons of the lateral suprasylvian area of the cerebral cortex in the cat].
Two-dimensional spatial-frequency characteristics of the receptive fields of 46 neurons in the lateral suprasylvian area were analyzed in awake cats. Extreme spatial frequencies were disposed in the range less than 1.5 cycle/deg. Spatial-frequency bands were measured for 21 neurons, their mean value was 1.47 +/- 0.5 octaves. 17 neurons had inhibitory characteristics if testing gratings were of nonoptimal orientations. For 6 neurons the inhibitory characteristics measured with nonoptimal orientations were in form of a narrow band with mean value of 1.47 +/- 0.6 octaves.
