… A new model of contour extraction and perceptual grouping in the primary visual cortex is
presented and discussed. It differs from previous models since it incorporates four main …

… We studied these processes in the primary visual cortex (V1), where neurons are thought
to integrate visual inputs along contours defined by an association field (AF). We recorded …
