Our results of YBOC testing may indicate an interactive function of different visual neural subsystems, including the parvo-, magno- and koniocellular systems .
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 .
4 Based on neurological models of vision, it has been postulated that these problems occur as a result of both damage and (stress-related) dysfunction of the magno-, parvo-, and konio-cellular pathways.
A number of studies have shown deficits in magno-, parvo-, and konio- cellular pathways in patients with PD.
This enables us to conceptualise the dorsal stream of visual information as related to localisation in space, in contrast to the ventral stream, which is more important for object identification, with less of a distinction between the magno-, parvo- and konio-cellular structures that intermingle through both streams.
33) It is well known that glaucoma causes a loss of visual field due to neurological damage to magno-, parvo- and konio-cellular pathways, within the optic nerve; in fact this can lead to a three-fold increase in the risk of falls and motor vehicle accidents, than persons of the same age without the condition.
