[Dynamic thermomapping of the brain of the rat during sensory stimulation and spreading depression].
Dynamics of spatial distribution of temperature over the dorsal surface of white rat cerebral cortex was studied through the skull with the thermovision technics. Visual, somatosensory and acoustic stimulation revealed both diffuse and regionally specific thermoreactions of the brain as well as multiple local termoresponses. After injection of KCl into the cortex temperature waves spreading over the cortex were obtained. Mechanisms of brain patterned thermoreactions dealing with blood flow and neuronal metabolic thermoproduction are discussed.
