Abstract

The medial interlaminar nucleus (MIN) of the cat's dorsal lateral geniculate nucleus was studied under the light and electron microscopes and compared with the A laminae. At the light level, MIN has more axons and a lesser cell packing density than the A laminae. Examined at the electron microscopic level, MIN could not qualitatively be distinguished from the A laminae. When quantitative counts of the profiles containing synaptic vesicles were made, MIN had less F profiles and more RSD profiles per unit area than the A laminae. Structure/function correlations suggest that additional F terminals may mediate nondominant eye inhibition and/or a greater amount of inhibition on X-cells versus Y-cells.

摘要

在光学显微镜和电子显微镜下对猫外侧膝状体核的内侧层间核(MIN)进行了研究,并与A层进行了比较。在光学水平上,MIN的轴突比A层更多,细胞堆积密度更低。在电子显微镜水平上,MIN与A层在质量上无法区分。当对含有突触小泡的轮廓进行定量计数时,MIN每单位面积的F轮廓比A层少,RSD轮廓比A层多。结构/功能相关性表明,额外的F终末可能介导非优势眼抑制和/或对X细胞与Y细胞的更大抑制量。
