大脑皮质体感Ⅰ区向丘脑中央外侧核一级投射纤维起源的研究
摘要
近年来
大量的针刺镇痛研究资料表明
大脑皮层体感Ⅰ区(SⅠ区)和丘脑中央外侧核与痛和针刺镇痛关系密切。如电刺激猫牙髓
可在皮质体感Ⅰ区记录到由Aδ传入纤维引起的皮层诱发电位。当电针“下关”等穴时
则可抑制皮质体感Ⅰ区内的这种诱发电位。表明皮质体感Ⅰ区即可以接受痛信息
又可接受针刺穴位的信息。中央外侧核是丘脑内参与针刺镇痛的重The origin of the somato-sensory area I(SI) projecting to the central lateral nucleus(CL) was studied with the method of horseradish peroxidase (HRP) in the cat. Following the introducing of HRP into the central la- teral nucleus
