New insights into the role of motion and form vision in neurodevelopmental disorders
2017, Neuroscience and Biobehavioral ReviewsCitation Excerpt :A third koniocellular pathway has also been identified (Casagrande, 1994; Hendry and Yoshioka, 1994; Hendry and Reid, 2000; Kaas et al., 1978) but its precise functional role is yet to be fully elucidated (see Roe et al., 2012 for review). It is not uncommon for the subcortical magnocellular and parvocellular pathways to be conflated with the cortical dorsal and ventral processing streams (Skottun, 2015, 2016). For many years, the magnocellular and parvocellular pathways were thought to provide major feedforward input to the dorsal and ventral processing streams, respectively (Livingstone and Hubel, 1988; Merigan and Maunsell, 1993; Zeki and Shipp, 1988).
