A neural model of contour integration in the primary visual cortex
Z Li - Neural computation, 1998 - direct.mit.edu
Experimental observations suggest that contour integration may take place in V1. However,
there has yet to be a model of contour integration that uses only known V1 elements …

Contour integration and cortical processing
Our understanding of visual processing in general, and contour integration in particular, has
undergone great change over the last 10 years. There is now an accumulation of …

Interactions between feedback and lateral connections in the primary visual cortex
Perceptual grouping of line segments into object contours has been thought to be mediated,
in part, by long-range horizontal connectivity intrinsic to the primary visual cortex (V1), with a …

Visual segmentation by contextual influences via intra-cortical interactions in the primary visual cortex
Z Li - Network: computation in neural systems, 1999 - Taylor & Francis
Stimuli outside classical receptive fields have been shown to exert a significant influence
over the activities of neurons in the primary visual cortex. We propose that contextual …

A neural model of how horizontal and interlaminar connections of visual cortex develop into adult circuits that carry out perceptual grouping and learning
S Grossberg, JR Williamson - Cerebral cortex, 2001 - academic.oup.com
A neural model suggests how horizontal and interlaminar connections in visual cortical
areas V1 and V2 develop within a laminar cortical architecture and give rise to adult visual …
