In tree shrews (Tupaia glis) reared with one eye closed, Y-cells were almost entirely absent in the binocular segment of the lateral geniculate laminae receiving input from the deprived eye. Y-cells were found in the monocular segment of these laminae, and in the binocular segment of the laminae with input from the normal eye. X-cells were present in both the deprived and normal laminae and appeared unaffected by the deprivation. A number of abnormal cells were also found, and these were located primarily in the binocular segment where Y-cells were absent.
在单眼闭合饲养的树鼩（笔尾树鼩）中，外侧膝状体板层接受来自被剥夺眼输入的双眼段几乎完全没有Y细胞。在这些板层的单眼段以及接受来自正常眼输入的板层双眼段中发现了Y细胞。X细胞在被剥夺和正常的板层中均存在，且似乎不受剥夺的影响。还发现了一些异常细胞，这些细胞主要位于没有Y细胞的双眼段。
