[Role of the exterior geniculate bodies and superior colliculus in the system that collects and accumulates visual information]

An analysis of picture on- and off-decompositions by retina ganglion cells and ipsi- and contralateral projections interleaving in lateral geniculate bodies (LGB) layers lead to founding earlier unknown LGB function-the logic filtering of the accurate (common in two approximations) parts of images. On- and off-splitting guarantees non-depended picture over and below approximations and reliable performing the above filtering function in the LGB layers. System complementation to LGB function is retinotopic mapping of non-percept pixels. It relates to primary superior colliculus (SC) function. Correlation between LGB and SC functions and saccade eye movements is discussed. Neurological nets for LGB and for a part of SC which realize the specified processor functions are presented.
