Parameters of photic stimulation and characteristics of thermoreactions in the cerebral cortex of the white rat

: The dynamics of local thermoresponses in the brain cortex was studied through the unopened scull under patterned light stimulation of the retina in acute experiments on white rats by means of thermovision and digital image processing technique. The dependence of the amplitude, temporal and spatial characteristics of these responses on the size, retinal localization, focusing of the stimulus, its duration, number and frequency of presentation was estimated. The properties, significance and mechanisms of the revealed thermoeffects are discussed.
