We have studied the suppression of firing in single LGN cells of cat and monkey in response to visual stimulation of the nondominant eye. In the cat LGN most of the cells of each of the main laminae show this nondominat suppression. X cells having their dominant input from the ipsilateral eye were suppressed to a significantly greater degree than any other cell type in the cat LGN. In the monkey LGN nondominant suppression was absent in all 19 X-like cells studied, whereas 6 of 21 Y-like cells showed nondominant suppression. Thus nondominant suppression is present in the magnocellular laminae of the monkey LGN, where the Y-like cells are found, but appears to be absent from the parvocellular laminae, where the X-like cells are found.
我们研究了猫和猴的外侧膝状体（LGN）单个细胞对非优势眼视觉刺激的放电抑制情况。在猫的LGN中，每个主要层的大多数细胞都表现出这种非优势抑制。来自同侧眼的优势输入的X细胞比猫LGN中的任何其他细胞类型受到的抑制程度都要显著更大。在猴的LGN中，所研究的全部19个类X细胞均未出现非优势抑制，而21个类Y细胞中有6个表现出非优势抑制。因此，非优势抑制存在于猴LGN的大细胞层，即发现类Y细胞的地方，但在发现类X细胞的小细胞层似乎不存在。
