Abstract

In acute experiments on immobilized or anesthetized white rats the spatial distribution and dynamics of temperature on the dorsal surface of the cerebral cortex were investigated by the thermovision technique and digital image processing through the intact skull. Under certain conditions the appearance of moving thermowaves that spread over the cortex for 8-30 mm during 2-9 s with a rate of 2-10 mm/s was found. Among the trajectories of these waves the circular one was more common: it began in one hemisphere, spread in one or another direction, then went over to the second hemisphere, moved in the opposite direction and came back to the initial zone. Linear and semicircular trajectories were found as well with or without crossing from one hemisphere to the other. The mechanisms and possible functional significance of the effect are discussed.

摘要

在对固定或麻醉的白鼠进行的急性实验中,通过热成像技术和经完整颅骨的数字图像处理,研究了大脑皮质背表面温度的空间分布和动态变化。在某些条件下,发现了移动热波的出现,这些热波在皮质上传播8 - 30毫米,持续2 - 9秒,速度为2 - 10毫米/秒。在这些波的轨迹中,圆形轨迹更为常见:它始于一个半球,向一个或另一个方向传播,然后进入第二个半球,向相反方向移动并回到初始区域。也发现了线性和半圆形轨迹,有或没有从一个半球交叉到另一个半球的情况。讨论了该效应的机制和可能的功能意义。
