Abstract:
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.

Motor and Sensory Areas of the Cortex
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
Association Areas of the Cortex
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
