WebAffected individuals display a unique neurobehavioural phenotype that includes striking visual-motor deficits. Here we provide neurobiological and behavioural evidence that supports the hypothesis that these visual-motor deficits are attributable to a magnocellular (M) visual pathway impairment. Webcell (a single bipolar cell) is a characteristic of the rod pathway, and the same sort of convergence also occurs in the cone pathway in the peripheral retina. o Pooling of information from many photoreceptors is a very important mechanism for increasing visual sensitivity. o Most rods communicate with ganglion cells through diffuse bipolar cells …
WebJan 1, 2015 · Magno-, parvo-, and koniocellular pathways are the three visual pathways in primates. These pathways are established at the level of the lateral geniculate nucleus (LGN) of the thalamus.
