Chromatic Inputs to Cortical Receptive Fields in Primates

人眼包含三种白天视觉感受器，分别命名为蓝色、绿色和红色锥体，因为它们对可见光光谱的不同区域敏感。众所周知，蓝色视锥细胞有助于大脑的颜色视觉通路，但最近的数据表明，蓝色视锥信号也与运动和高敏锐度视觉通路存在“串扰”。该项目包括在人类视觉的灵长类动物模型中精确测量蓝锥信号，并对蓝锥路径进行解剖跟踪。这些数据将提高我们对大脑如何处理感觉信号的基本知识。

The human eye contains three kinds of receptors for daytime vision, named blue, green and red cones for their sensitivity to different regions of the visible spectrum. It is known that blue cones contribute to brain pathways for colour vision, but recent data suggest there is also 'cross-talk' of blue cone signals to pathways for motion and high-acuity vision. This project comprises precise measurement of blue cone signals, and anatomical tracing of blue cone pathways, in a primate model for human vision. The data will improve our basic knowledge of how the brain processes sensory signals.
