9) The magnocellular pathway begins at the level of parasol retinal ganglion cells (RGCs) and transmits signals through to the cortex slightly differently to the parvocellular pathway.
In comparing the patients with anisometropic amblyopia and the normal group, both the stimuli of the parvocellular pathway (100% contrast and high spatial frequency as the features of the parvocellular system) and the magnocellular pathway (30% contrast and low spatial frequency as the features of the magnocellular system) showed a significant reduction in the amplitude of the wave.
4) tend to be most indicative of the magnocellular pathway function (mesopic luminance conditions, lower spatial frequencies).
Abnormalities in the magnocellular pathway in the visual system.
21,32) It was further hypothesised that these were the retinal ganglion cells that formed part of the magnocellular pathway.
