Sensory mapping of the rat cerebral cortex by thermographic methods

: Using thermovision and digital image processing, the dynamics of thermomap in the brain cortex has been studied on albino rats through the opened skull before and during sensory stimulation. Photic, sonic and somatosensory stimuli lead to the onset of local heating foci in the corresponding cortical zones, as well as to local multiple thermoresponses in other areas. Some quantitative parameters of these effects are given and their possible mechanisms are discussed.
