当我们观看彩色图片时，我们的大脑中随机的彩色点图片和通过彩色点看到的数字图形图片有什么不同？我们创建了3个模式，这是石原板模式的功能性磁共振成像版本，以测试人类腹侧枕颞叶皮层中的多个颜色敏感区域。结果表明，在Ishihara假等色板上，从V4区的色点上阅读出形状的刺激使V4区激活，而随机色点图片刺激则使V4区不激活。我们认为V4区的激活不是通过颜色加工，而是通过分离。
When we are viewing colored picture, what is the difference in our brain between a random Color dot picture and a digit figure pattern picture seen through its colored dots? We created 3 patterns that are a functional magnetic resonance imaging version of the Ishihara plate patterns to test multiple color-sensitive areas in human ventral occipitotemporal cortex. The results showed that area V4 is activated by the stimulus of reading shapes from its color dots in the Ishihara pseudoisochromatic plates but not by the stimulus of seeing a random color dot picture. We suggest that area V4 is activated not by color processing but by segregation.
