Abstract	Orientation selective cells in the primary visual cortex of monkeys and cats are often characterized by an orientation-tuning width that is invariant under stimulus contrast. At the same time their contrast response function saturates or even supersaturates for high values of contrast. When two bar stimuli are presented within their classical receptive field, the neuronal response decreases with intersection angle. When two stimuli are presented inside and outside the classical receptive field, the response of the cell increases with intersection angle. Both cats and monkeys show iso-orientation suppression, which was sometimes reported to be combined with crossorientation facilitation. This property has previously been described as sensitivity to orientation contrast. We address
