Abstract

The ability to discriminate a bar from visual background noise was investigated for single neurons in the LGN and in area 17 in the cat. Without relative movement between the signal and the noise, the S/N discrimination threshold for X- and Y-cells of the LGN and the cortical complex cells was about equal. Simple cells showed a lower threshold. With relative movement the detection threshold was much lower and again equal in X-cells, Y-cells and complex cells. It was higher in simple cells in this condition. Possible mechanisms leading to the different transformations of the LGN input in simple and complex cells are discussed.
