There have been a number of advances in the search for the neural correlates of consciousness--the minimum neural mechanisms sufficient for any one specific conscious percept. In this Review, we describe recent findings showing that the anatomical neural correlates of consciousness are primarily localized to a posterior cortical hot zone that includes sensory areas, rather than to a fronto-parietal network involved in task monitoring and reporting. We also discuss some candidate neurophysiological markers of consciousness that have proved illusory, and measures of differentiation and integration of neural activity that offer more promising quantitative indices of consciousness.
在寻找意识的神经相关物——任何一个特定意识知觉所必需的最小神经机制——的过程中，已经取得了许多进展。在这篇综述中，我们描述了最近的发现，表明意识的解剖学神经相关物主要局限于包括感觉区域的后皮质热点区，而不是参与任务监测和报告的额顶网络。我们还讨论了一些被证明是虚幻的意识候选神经生理标记，以及对神经活动的分化和整合的测量，这些测量为意识的更有前途的定量指标提供了依据。
