Cone Signals and the Functional Anatomy of Visual Cortex

使用一种新颖而创新的技术来绘制大脑皮层中特定的光感受器活动的实验旨在为关键问题提供答案，这些问题涉及颜色信息在视觉通路的最高水平是如何处理的。这些研究应该有助于解决人类视觉中一个长期悬而未决的问题，并开创一种相当简单的技术，用于研究大多数其他视觉系统，这些视觉系统在引导行为中使用颜色信息。这是首次尝试使用锥体光感受器隔离刺激，通过代谢标记物2-脱氧葡萄糖来绘制初级视觉皮质的活动图，有望成为了解皮层颜色感知机制的非常强大的新工具。

Experiments using a novel and innovative technique for mapping specific photoreceptor activities in the cerebral cortex are designed to provide answers to crucial questions about the way in which color information is processed at the highest levels of the visual pathway. These studies should help to resolve a long outstanding problem in human vision and pioneer a fairly straightforward technique for the study of most other visual systems that use color information in guiding behavior. This is the first such attempt to use cone photoreceptor-isolating stimuli to map activity in the primary visual cortex using the metabolic marker, 2- deoxyglucose and promises to be a very powerful new addition to understanding cortical mechanisms of color perception.
