Past observations revealed a relationship between mammalian retinal ganglion cell distribution and cortical and subcortical projection of the rabbit's visual field. High ganglion cell density sectors of the retina claimed larger areas in their cortical and subcortical projections (with a high magnification factor) than retinal areas with low ganglion cell density. In this study, it was observed that distribution of nonpyramidal neurons in laminae IV and VI of the pigmented rabbit's visual cortex was not uniform. The nonuniformity in layer IV roughly followed the variation in the magnification factor in the cortical projection of the animal's visual field. The highest density of nonpyramidal neurons in layer IV was observed in the cortical area with the highest magnification factor.
以往的观察结果揭示了哺乳动物视网膜神经节细胞分布与兔视野的皮质及皮质下投射之间的关系。视网膜神经节细胞密度高的区域在其皮质及皮质下投射中（具有高放大因子）所占面积比神经节细胞密度低的视网膜区域更大。在本研究中，观察到色素沉着兔视觉皮质IV层和VI层中非锥体神经元的分布并不均匀。IV层的不均匀性大致遵循动物视野皮质投射中放大因子的变化。在具有最高放大因子的皮质区域观察到IV层中非锥体神经元的密度最高。
