Disorder of higher visual function

Abstract: These studies advance our understanding of the mechanisms of complex visual processing and provide an important neuropsychological complement to our expanding knowledge about vision from functional neuroimaging.

“…We speculate that bilateral human motionsensitive regions such as MT/V5 and MST (Tootell et al, 1995;Heeger et al, 1999;Rees et al, 2000;Kolster et al, 2010) and also V3A (Tootell et al, 1997a;McKeefry et al, 2010) may well process motion equivalently, and that the laterality effect we have observed is related to the dominance of the right hemisphere in form and object perception. Although form and object representations activate both hemispheres (Gilaie-Dotan et al, 2008, neuropsychological studies suggest that the right ventral cortex plays a more critical role in object recognition (Humphreys and Riddoch, 1984;Davidoff and Warrington, 1999;Barton, 2011;Konen et al, 2011). Left ventral lesions do not typically give rise to profound agnosia, and instead, tend to result in deficits in visual word recognition (Behrmann et al, 1998;McKeeff and Behrmann, 2004).…”

“…Functions of sensory organs can be impaired as a result of peripheral nervous system damage leading to complete loss of senses (deafness, blindness) and as a result of damage to the organs that process sensory information of a higher level (thalamus, cerebellum, basal ganglia, brain cortex); the latter does not cause a complete loss of sensitivity, though. An interesting example is blindsight in patients with damaged visual cortex; they are blind but still can sense and process visual stimuli subconsciously [74].…”

“…Поскольку эти процессы носят комплексный характер и для их преодоле-ния используются различные стратегии, то выделяют раз-личные подвиды топографагнозии (агнозия на достоприме-чательности, агнозия на знакомые здания, нарушение ори-ентировки в знакомой карте местности и пр.) [4]. В ряде случаев в основе подобных нарушений лежит патология гиппокампа в рамках начинающейся болезни Альцгеймера.…”
