The spectral sensitivities of single on- and off-centre, brisk sustained and brisk transient cells recorded from the A laminae of the lateral geniculate nucleus (LGNd) in cats anaesthetised with nitrous oxide and oxygen supplemented with halothane were measured under photopic and mesopic achromatic adapting conditions. All cells possessed spectral sensitivity functions with a single peak at about 556 nm under photopic conditions. Intense chromatic adapting fields superimposed on the photopic background affected neither the shape of the spectral sensitivity functions nor the position of the peak wavelength. Under mesopic adapting conditions cells possessed spectral sensitivities with two peaks, one at 507 nm and one at 556 nm. These results are interpreted as suggesting that the cells of the A laminae of the LGNd receive inputs from rods with maximum sensitivity at 507 nm and a single class of cones maximally sensitive at 556 nm.
在用一氧化二氮和补充了氟烷的氧气麻醉的猫的外侧膝状核（LGNd）A层中记录的单个开中心和闭中心、快速持续和快速瞬态细胞的光谱敏感性，在明视觉和中间视觉消色差适应条件下进行了测量。在明视觉条件下，所有细胞都具有在约556nm处有单个峰值的光谱敏感性函数。叠加在明视觉背景上的强烈彩色适应场既不影响光谱敏感性函数的形状，也不影响峰值波长的位置。在中间视觉适应条件下，细胞具有两个峰值的光谱敏感性，一个在507nm，一个在556nm。这些结果被解释为表明LGNd A层的细胞接收来自在507nm处具有最大敏感性的视杆细胞和在556nm处具有最大敏感性的单一类视锥细胞的输入。
