许多色刺激的检测是由它们的输入线性求和的机制介导的。因此，这些机制在色彩空间中具有广泛的选择性，就像大多数细胞在视觉处理的早期阶段一样。在层外皮层，有一些细胞在色彩空间上具有狭窄的调谐。这些细胞的功能尚不完全清楚：它们可能参与颜色分类，也可能介导对刺激的检测，如玻璃图案，其特性使其在处理的早期阶段无法检测到。我们测量了负责检测彩色玻璃图案的机制的调谐特性，发现它们在色彩空间中具有广泛的调谐。我们的研究结果表明，玻璃图案是通过多种机制来检测的，这些机制线性地总结了它们的输入。
The detection of many chromatic stimuli is mediated by mechanisms that sum their inputs linearly. As a result, these mechanisms have a broad range of selectivity in color space, as do the majority of cells in the early stages of visual processing. In extrastriate cortex, there are cells with a narrow tuning in color space. The function of these cells is not fully understood: they could be involved in color categorization, or could mediate the detection of stimuli such as Glass patterns, whose properties make them undetectable by early stages of processing. We measured the tuning properties of the mechanisms responsible for the detection of colored Glass patterns and found that they have a broad tuning in color space. Our results suggest that Glass patterns are detected by a multitude of mechanisms that sum their inputs linearly.
