| Abstract: | Neurophysiological processes of transduction and analysis of information concerning brightness of photostimuli and peculiarities of functioning of visual system under exposure to extra-bright light effects or extreme contrasting of visual objects are studied poorly and present significant interest for unraveling actual mechanisms of visual perception under extreme conditions. Conducting analysis of visual system in maximal broad range both in terms of adequate perception and reflection of light stimulus intensity and adaptive mechanisms to extra-strong illumination regimes is as well very important. The to-date obtained data indicate that under the extreme light effects pathology of the peripheral portion of visual analysator can be induced. The presented review does not pretend to comprise all present information concerning all achievements and results over this problem. Its goal concludes in maximal approaching to understanding the mechanisms of damaging and following recover of visual function under extreme effects of affecting light factors. |
