The spatial and spectral topography of the cone mosaic set the limits for detection and discrimination of chromatic sinewave gratings. Here, we sought to compare the spatial characteristics of mechanisms mediating hue perception against those mediating chromatic detection in individuals with known spectral topography and with optical aberrations removed with adaptive optics. Chromatic detection sensitivity in general exceeded previous measurements and decreased monotonically for increasingly skewed cone spectral compositions. The spatial grain of hue perception was significantly coarser than chromatic detection, consistent with separate neural mechanisms for color vision operating at different spatial scales.

锥形光谱形貌对色彩检测灵敏度的影响。



锥形镶嵌体的空间和光谱形貌设定了彩色正弦波光栅的检测和辨别的极限。在这里,我们试图将介导色调感知的机制的空间特征与介导具有已知光谱地形并通过自适应光学消除光学像差的个体的色彩检测的空间特征进行比较。色彩检测灵敏度总体上超过了之前的测量结果,并且随着倾斜锥体光谱成分的增加而单调下降。色调感知的空间颗粒明显比色彩检测更粗糙,这与在不同空间尺度上操作的颜色视觉的单独神经机制一致。
