Parallel visual pathways in humans. (A) The monkey visual system is characterized by a set of parallel, hierarchical, multistage systems. There are two major parallel streams: parvocellular (or ventral) and magnocellular (or dorsal) pathways (see section Concept of Parallel Visual Pathways for more detailed information). (B) The human visual system is analogous to that of the monkey. Two major parallel streams: parvocellular (or ventral) and magnocellular (or dorsal) pathways are present. (C) The ventral stream corresponds to the ILF (orange) and IFOF (yellow), while the dorsal stream is related to the SLF (sky-blue) ([C] Modified from Jang, 2013 with no permission was required to reproduce). d-d pathway, dorso-dorsal pathway; v-d pathway, ventro-dorsal pathway; LGN, lateral geniculate nucleus; MT, middle temporal area; MST, medial superior temporal area; IPL, inferior parietal lobule, SPL, superior parietal lobule; IT, inferior temporal cortex; SLF, superior longitudinal fasciculus, IFOF, inferior fronto-occipital fasciculus; ILF, inferior longitudinal fasciculus.
