The diffusion of horseradish peroxidase was restricted to layers I and II of the striate cortex in Tupaia glis and Galago senegalensis. In the lateral geniculate body of Tupaia labeled cells were found only in layer 3; some labeled cells were also found in the lateral nucleus. In Galago labeled cells were found only in layers 4 and 5 of the lateral geniculate body; a band of cells was also found in the pulvinar nucleus. These results support the distinction between two overlapping thalamic systems, a layer I and a layer IV system.
在树鼩和塞内加尔婴猴中，辣根过氧化物酶的扩散仅限于纹状皮层的第I层和第II层。在树鼩的外侧膝状体中，仅在第3层发现标记细胞；在外侧核中也发现了一些标记细胞。在婴猴中，仅在外侧膝状体的第4层和第5层发现标记细胞；在丘脑枕核中也发现了一排细胞。这些结果支持了两种重叠丘脑系统的区分，即第I层系统和第IV层系统。
