| 摘 要： | 外侧膝状体背核(DLG)的突触构成成份主要来自视网膜、视皮质、丘脑网状核的轴突终末和DLG内神经元的突起。视网膜和视皮质来的轴突终末对DLG投射神经元和中间神经元的树突形成非对称性突触,丘脑网状核的轴突终末则对这两类神经元构成对称性突触,而中间神经元树突具有轴突样作用,对投射神经元树突形成对称性突触。这些结果有助于我们了解视觉信息在DLG内的加工处理过程。

THE PRINCIPAL SYNAPTIC ORGANIZATION IN THE DORSAL LATERAL GENICULATE NUCLEUS OF RAT |
| |
| Abstract: | The principal synaptic profiles in the dorsal lateral geniculate(DLG)of rat are mainly comprised by synaptic terminals origining from retina,visual cortex,thalamic reticular nucleus and processes of DLG neurons,The corticofugal terminals and retinal terminals establish asymmetrical synaptic contacts with dendrites of relay cells and interneurons of the DLG.Terminals coming from thalamic reticular nucleus establish symmetrical synaptic contacts with these dendrites.Dendrites of the DLG interneurons also act as axons and establish symmetrical synapses on the dendrites of relay cells.This result may provid some informations for understanding the functional machanism of the DLG. |
