摘要
在大白鼠束旁核(PF)和上丘(SC)深部(中、深层)微电泳导入HRP溶液,用逆行标记法证明脊髓灰质全长有脊髓—PF投射和脊髓—SC深部投射。两种投射的标记细胞主要分布在脊髓Rexed第Ⅳ、Ⅴ及Ⅰ、Ⅱ层,前角偶有少量标记细胞。脊髓—PF为双侧投射,脊髓—SC深部主要为对侧投射。PF和SC之间有SC—PF单向投射,未见有PF—SC直接投射。
The cells of the spinal gray(SG)which project to the deep layers of the superior colliculus(SC)and the nucleus parafascicularis(PF)in the rat were identified by means of the Free-horseradish peroxidase(F-HRP)retrograde tracing technique.SG-PF cells were seen throughout the whole length of the spinal cord in the Rexed laminae Ⅳ-Ⅴ,Ⅰ-Ⅱ and a small number of labelled cells were also observed in the ventral horns,bilaterally.SG-SC cells were also distributed mainly in the Rexed laminae Ⅳ-Ⅴ,Ⅰ-Ⅱ and the ventral horn of the spinal cord contralateral to the injection site.The projection of SCPF has been demonstrated,but not of PF-SC.
