It's supposed that the main function of perception is detection of distinctions in ambient environment. The spherical model of visual signals' distinction is offered. The model is constructed using multidimensional methods in frameworks of approach "HumanModelNeuron" developed by E.N. Sokolov. The signals differentiated by human or animal are represented by points at a surface of spherical space. The model combines neurophysiological and psychological (psychophysical, behavioral) data concerning visual perception in both human and animals. Contributions of neural mechanisms into visual perception are represented by Decart's coordinates of points-stimuli, and subjective characteristics of perceived stimuli are described by their spherical coordinates. A connection between physical and subjective parameters of signals is realized by two-channel neural modules that are considered to be an original "alphabet" of "visual perception language".
