Indeed, the magnocellular system is involved in recognition of movement, spatial perception, and luminosity, meanwhile parvocellular on identification of color and form.
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.
Parasol cells process dynamic information and form the basis of the magnocellular system.
The parvocellular system may be very important in color discrimination, spatial resolution, depth perception, stereopsis and object detection [26], whereas the magnocellular system has shown a significant role in motion perception, luminance and contrast perception [28].
These environmental visual pieces of information, which are instantly transmitted through the parvo- and magnocellular systems to the visual cortex, determine the sensory-motor behavior of players [32].
The magnocellular system is specialized for timing visual events and hence for detecting visual motion.
Dyslexia: the role of the magnocellular system. Notes from presentation at The British Dyslexia Association International Conference, York, UK.
The magnocellular system is important for processing rapidly changing information and projects to both subcortical and cortical brain areas, including the primary visual cortex.
That finding is provocative because V5 belongs to a part of the visual system known as the magnocellular system. This system shares the duties of processing visual information with the parvocellular system.
Visual mid-line shift syndrome results from dysfunction of the magnocellular system, which causes a shift in concept of the visual mid-line.

It is this visual processing stream that also forms the basis of the Frequency Doubling Technology (FDT) employed by a perimeter manufactured by Carl Zeiss Meditec, since it is believed that damage to the magnocellular system in early glaucoma can be detected before threshold testing methods.
