A Reaction-Diffusion Model to Capture Disparity Selectivity in Primary Visual Cortex
Decades of experimental studies are available on disparity selective cells in visual cortex of macaque and cat. Recently, local disparity map for iso-orientation sites for near-vertical edge preference is reported in area 18 of cat visual cortex. No experiment is yet reported on complete disparity map in V1. Disparity map for layer IV in V1 can provide insight into how disparity selective compl...
متن کاملBinocular integration and disparity selectivity in mouse primary visual cortex.
Signals from the two eyes are first integrated in primary visual cortex (V1). In many mammals, this binocular integration is an important first step in the development of stereopsis, the perception of depth from disparity. Neurons in the binocular zone of mouse V1 receive inputs from both eyes, but it is unclear how that binocular information is integrated and whether this integration has a fun...
متن کاملDisparity processing in primary visual cortex.
The first step in binocular stereopsis is to match features on the left retina with the correct features on the right retina, discarding 'false' matches. The physiological processing of these signals starts in the primary visual cortex, where the binocular energy model has been a powerful framework for understanding the underlying computation. For this reason, it is often used when thinking abo...
متن کاملTesting quantitative models of binocular disparity selectivity in primary visual cortex.
Disparity-selective neurons in striate cortex (V1) probably implement the initial processing that supports binocular vision. Recently, much progress has been made in understanding the computations that these neurons perform on retinal inputs. The binocular energy model has been highly successful in providing a simple theory of these computations. A key feature of the energy model is that it is ...
متن کاملA self-organizing model of disparity maps in the primary visual cortex
Current models of primary visual cortex (V1) development show how visual features such as orientation and eye preference can emerge from spontaneous and visually evoked neural activity, but it is not yet known whether spatially organized maps for low-level visual pattern disparity are present in V1, and if so how they develop. This report documents a computational approach based on the LISSOM m...
