Editing Motion perception (section)

==Neuropsychology==
The inability to perceive motion is called [[akinetopsia]] and it may be caused by a lesion to [[Cerebral cortex|cortical]] area [[Visual cortex#V5/MT|V5]] in the [[extrastriate cortex]]. [[Neuropsychology|Neuropsychological]] studies of a patient who could not see motion, seeing the world in a series of static "frames" instead, suggested that visual area V5 in humans<ref>{{cite journal | vauthors = Watson JD, Myers R, Frackowiak RS, Hajnal JV, Woods RP, Mazziotta JC, Shipp S, Zeki S | display-authors = 6 | title = Area V5 of the human brain: evidence from a combined study using positron emission tomography and magnetic resonance imaging | journal = Cerebral Cortex | volume = 3 | issue = 2 | pages = 79–94 | date = 1993 | pmid = 8490322 | doi = 10.1093/cercor/3.2.79 }}</ref> is homologous to motion processing area V5/MT in primates.<ref>{{cite journal | vauthors = Zeki SM | title = Functional organization of a visual area in the posterior bank of the superior temporal sulcus of the rhesus monkey | journal = The Journal of Physiology | volume = 236 | issue = 3 | pages = 549–73 | date = February 1974 | pmid = 4207129 | pmc = 1350849 | doi = 10.1113/jphysiol.1974.sp010452 }}</ref><ref name=Hess1989>{{cite journal | vauthors = Hess RH, Baker CL, Zihl J | title = The "motion-blind" patient: low-level spatial and temporal filters | journal = The Journal of Neuroscience | volume = 9 | issue = 5 | pages = 1628–40 | date = May 1989 | pmid = 2723744 | pmc = 6569833 | doi = 10.1523/JNEUROSCI.09-05-01628.1989 | doi-access = free }}</ref><ref name=Baker1991>{{cite journal | vauthors = Baker CL, Hess RF, Zihl J | title = Residual motion perception in a "motion-blind" patient, assessed with limited-lifetime random dot stimuli | journal = The Journal of Neuroscience | volume = 11 | issue = 2 | pages = 454–61 | date = February 1991 | pmid = 1992012 | pmc = 6575225 | doi = 10.1523/JNEUROSCI.11-02-00454.1991 | doi-access = free }}</ref>
