The responses of parvocellular and magnocellular cells in the monkey lateral geniculate nucleus (LGN) were assessed to red-green color substitution at various luminance ratios. Parvocellular LGN cells lacking well defined color selectivity could be rendered unresponsive to red-green light exchange at specific luminance ratios. By contrast, magnocellular LGN cells could not be silenced at any luminance ratio. The difference between these two types of cells is attributable to the greater sensitivity of magnocellular cells. The results suggest that magnocellular cells are well suited for the detection of any spatially localized change, be it the result of luminance or wavelength change.
研究人员评估了猕猴外侧膝状核（LGN）中的小细胞和大细胞对不同亮度比例下红-绿颜色替换的反应。缺乏明确颜色选择性的小细胞LGN细胞在特定亮度比例下可能对红-绿光线交换无反应。相比之下，大细胞LGN细胞在任何亮度比例下都不会沉默。这两种细胞类型之间的差异归因于大细胞的更高敏感性。结果表明，大细胞非常适合检测任何空间局部变化，无论是亮度变化还是波长变化的结果。
