人脑产生的电响应（EP）的变化，在色彩对比度的等亮度的空间图案的刺激，即使当眼睛的纵向和横向色差同时取消。图案EP强烈地受到眼睛色差的影响。EP和主观估计的纵向色差同意密切。心理物理对比度阈值与诱发电位的振幅相关的单色图案的检查，并通过等亮度模式的交替颜色的检查或bars.Restricting刺激的中央凹可能会增强的影响，受试者之间的变化的神经解剖学后EPs.Physiological信号似乎被隔离到颜色通道，直到第一次响应对比度。EP数据表明，存在与颜色编码的亮度对比度通道并行的反向组织的色度对比度通道。EP结果表明，人类视觉系统处理颜色信息时，颜色与空间形式的不同，而不是当颜色不与形式。
The human brain generated electrical responses (EPs) to changes in the chromatic contrast of an equiluminant spatially-patterned stimulus even when the eye's longitudinal and transverse chromatic aberrations were simultaneously cancelled. Pattern EPs were strongly affected by ocular chromatic aberration. EP and subjective estimates of longitudinal chromatic aberration agreed closely. Psychophysical contrast threshold correlated with the amplitudes of EPs elicited both by monochromatic patterns of checks and by equiluminant patterns of alternately-coloured checks or bars.Restricting stimulation to the fovea may enhance the effect of intersubject variations of neuroanatomy upon EPs.Physiological signals seem to be segregated into colour channels until the first responses to contrast. The EP data suggest that there is an antagonistically-organized chromati-contrast channel in parallel with colour-coded luminance-contrast channels. EP results suggest that the human visual system handles colour information differently when colour is linked with spatial form than when colour is not linked with form.
