Abstract

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.

摘要

利用热成像和数字图像处理技术,在白化大鼠开颅后,于感觉刺激前后对其大脑皮层热图的动态变化进行了研究。光、声和体感刺激会导致相应皮层区域出现局部加热灶,同时也会在其他区域引发局部多重热反应。给出了这些效应的一些定量参数,并对其可能的机制进行了讨论。
