对早期视觉皮层的视觉输入以快速和准确的方式与高级视觉皮层中的语义、语言和记忆输入相结合，并且能够进行复杂的计算，例如面部识别和文字阅读。这意味着存在着能够实现这种效率的基本组织原则。为了详细说明这一点，我们对82名个体进行了颅内记录，同时他们执行了不同视觉和认知复杂性的任务。我们发现，视觉输入诱导高度有组织的后向前传播模式的相位调制腹侧枕颞叶皮层。在个别电极有一个刻板的时间模式的阶段进展后，刺激的开始和偏移，在试验和任务一致。前区低频活动的相位由后皮层区域的先前相位预测。这种时空传播的阶段可能作为一个前馈组织的影响，使信息整合在腹侧视觉流。这种相位调制表现为事件相关电位的早期分量;人类电生理学中最常用的测量之一。这些发现阐明了高阶视觉系统的基本组织原则，使各种输入的快速识别和表征。
Visual inputs to early visual cortex integrate with semantic, linguistic and memory inputs in higher visual cortex, in a manner that is rapid and accurate, and enables complex computations such as face recognition and word reading. This implies the existence of fundamental organizational principles that enable such efficiency. To elaborate on this, we performed intracranial recordings in 82 individuals while they performed tasks of varying visual and cognitive complexity. We discovered that visual inputs induce highly organized posterior-to-anterior propagating patterns of phase modulation across the ventral occipitotemporal cortex. At individual electrodes there was a stereotyped temporal pattern of phase progression following both stimulus onset and offset, consistent across trials and tasks. The phase of low frequency activity in anterior regions was predicted by the prior phase in posterior cortical regions. This spatiotemporal propagation of phase likely serves as a feed-forward organizational influence enabling the integration of information across the ventral visual stream. This phase modulation manifests as the early components of the event related potential; one of the most commonly used measures in human electrophysiology. These findings illuminate fundamental organizational principles of the higher order visual system that enable the rapid recognition and characterization of a variety of inputs.
