title: Properties of visually driven neurons in cats pretectal region.
abstract: Properties of visually driven neurons in the cat pretectal region were studied. A detailed investigation of the receptive field (RF) structure revealed, in the majority of neurons, irregular shapes of RF contours. Dark-sensitive and bright-sensitive zones of a neuronal RF had different spatial locations. The majority of pretectal neurons were movement-sensitive and reacted weakly to stationary flashing spots. Although no clear-cut orientation sensitivity was found in the pretectal neurons, some orientations of motion were, nevertheless, more effective. In some cases a non-directional response could be transformed into a directionally-sensitive one by changing the orientation of motion. Out data confirm earlier observations that the pretectal region is involved in the central processing of visual information.
