[The spatial organization of the cortical potentials in exposure to different forms of photic stimuli].

Reactive changes of spatial-temporal organization of cerebral cortex potentials of rabbits under the action of light stimuli of various shapes (circle, square, triangle, cross and weaker diffusive light presented prior to and after the application of structural stimuli) were studied on the basis of multi-channel EEG recording data (24 leads). The data were evaluated of spectral-correlative analysis of the electrical activity and the results of comparison of successive momentary topograms of cortical potentials (EEG) on two-second segments prior to and during the action of the applied light stimulus. The obtained results showed that localization of interconnected changes of the cortical potentials were more sensitive to the perception of the form of light stimuli than the change of frequency characteristics of the EEG rhythms.
