翻译后摘要:摘要闪烁的长波长光出现更黄比稳定的光相同的平均强度。色调变化与视觉信号在某些非线性部位(或多个部位)处的失真一致,所述非线性部位产生原始刺激中不存在的时间分量(称为失真产物)。我们提取的时间衰减特性的早期(prenonlinearity)和晚期(postnonlinearity)过滤阶段的L-和M-锥色通路通过改变输入刺激来操纵失真产品和测量的观察者的敏感性。早期的线性滤波器级的作用类似于峰值在10-15 Hz的带通滤波器,在较低和较高频率下都有相当大的灵敏度损失。它的特点是一致的非线性是早期的视觉通路,但随后的周围抑制。相比之下,后级的作用就像一个截止频率约为3 Hz的低通滤波器。早期的响应随着辐射的增加而加快,但后期的响应没有。一个合理的网站的非线性,建模表明,可能是顺利压缩,但在高输入水平的硬限制,是从水平细胞周围抑制后。
Abstract:Abstract Flickering long-wavelength light appears more yellow than steady light of the same average intensity. The hue change is consistent with distortion of the visual signal at some nonlinear site (or sites) that produces temporal components not present in the original stimulus (known as distortion products). We extracted the temporal attenuation characteristics of the early (prenonlinearity) and late (post-nonlinearity) filter stages in the L-and M-cone chromatic pathway by varying the input stimulus to manipulate the distortion products and the measuring of the observers' sensitivity to them. The early, linear, filter stage acts like a band-pass filter peaking at 10–15 Hz with substantial sensitivity losses at both lower and higher frequencies. Its characteristics are consistent with nonlinearity being early in the visual pathway but following surround inhibition. The late stage, in contrast, acts like a low-pass filter with a cutoff frequency around 3 Hz. The response of the early stage speeds up with radiance, but the late stage does not. A plausible site for the nonlinearity, which modelling suggests may be smoothly compressive but with a hard limit at high input levels, is after surround inhibition from the horizontal cells.
