| Abstract: | Investigation of the spatial organization of detector neurons of the frog tectum opticum showed that these neurons are mainly in the nuclear layers. When responding to a photic stimulus they form a mosaic of groups of synergically excited cells separated by inhibited or nonresponding neurons. Inhibited neurons are much more numerous than excited. Different photic stimuli (shaped or diffuse) evoke the appearance of mosaics of different structure; mosaics connected with different forms of detection are to a considerable degree stratified.Rostov State University.
