| 摘 要： | <正> 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

A STUDY ON THE ORIGIN OF PROJECTION OF THE SOMATO--SENSORY AREA I TO THECENTRAL LATERAL NUCLEUS |
| |
| Abstract: | 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, numerous labeled cells, which belong to the medium-sized pyramidal cells(20-28u), were found in layer V of the ipsilateral SI area. |
