运动与脑血流量

人体进行随意运动时，支配前调节运动的大脑皮质的局部电运动增强，该区细胞代谢水平改变，从而局部脑血流量（rCBF）也发生变化。不同的rCBF的改变表示了相应运动涉及运动皮质的范围，其研究对认识脑的基本活动规律和特性有重要意义。本文简略介绍了rCBF的测量方法，并描述了受试者进行不同类型随意运动时皮质各个区域rCBF的变化和分布情况。

Changes in regiond Cerebral Blood Flow during Volantary

Bioeleotrical activities of human cerebral cortex which control and regalate movements get to increase during voluntary movements, the metabolic level of the cells of motor areas change at the same time,and consequently regiond cerebrd blood flow (rCBF)changes. Different changes of rCBF indicate the range of motor areas with which the relavant movemats are involved.And studies of this take great significance in finding out the basic active regalarity and features of human brain. In this artide motheds of the determination of rCBF an introduced briefly, and changes and distribution of rCBF of rCBF of each cortical moter area during different types of volantary movements are discribed.
