Given that cells in visual cortical area 18 in cats encode information of complex shapes, in addition to conventional stimuli like bars and gratings, we studied the capability of single cells in this area to ‘identify’ animated contours. The recorded cells were not selective to specific animated contours, whereas they were highly sensitive to the contour's degradation and to the orientation of its elements. The results indicate that cells in area 18 can encode information about many characteristics of complex animated patterns. The findings suggest the existence of a contour abstracting mechanism, which needs further study.
