[Spatial-frequency characteristics of the receptive fields of cat visual cortex with different rates of stimulus movement].

Velocity ranges exist for complex and simple receptive fields of cat's visual cortex. In these ranges there is a narrow band frequency tuning. In these velocity ranges the location of the maximum on frequency characteristics is constant and does not depend on the velocity of stimulating lattice movement. An increase of the movement velocity brings about a reduction of the reaction value of the receptive fields and a disappearance of the narrow band tuning expressed in the optimal velocity range.
