Abstract

In acute experiments on immobilized white rats, by thermovision methods and digital image processing, spatial distribution and dynamics of local heating and cooling of dorsal surface of the cerebral cortex was studied through intact skull during elaboration of a conditioned reflex. Distant and noninvasive thermovision methods allowed to reveal and quantitatively study local cortical thermal reactions in the somatosensory and motor cortex and in the cerebellum in the process of elaboration and testing of conditioned connection. Under discussion are mechanisms, properties and significance of these effects for investigation of learning.

摘要

在对固定的白鼠进行的急性实验中,通过热成像方法和数字图像处理技术,在建立条件反射的过程中,透过完整的颅骨研究了大脑皮质背表面局部加热和冷却的空间分布及动态变化。远距离且非侵入性的热成像方法能够在条件联系的建立和测试过程中,揭示并定量研究躯体感觉皮层、运动皮层以及小脑的局部皮质热反应。本文讨论了这些效应对于学习研究的机制、特性及意义。
