感知意识的神经关联，直到最近都是一个难以捉摸的猎物，现在几乎是司空见惯的发现。本文首先描述了基于fMRI、erp和单单元记录的感知意识的各种神经关联。然后有人认为，我们的探索最终不应该仅仅集中在意识的相关关系上，而应该集中在对知觉意识来说既必要又充分的神经事件上。事实上，初步证据表明，尽管已经报道的许多神经关联对于相应的意识状态可能是必要的，但它们不太可能是充分的。最后一节考虑了关于知觉的可能充分性条件的三个假设。(C) 2001 Elsevier Science B.V.版权所有
Neural correlates of perceptual awareness, until very recently an elusive quarry, are now almost commonplace findings. This article first describes a variety of neural correlates of perceptual awareness based on fMRI, ERPs, and single-unit recordings. It is then argued that our quest should ultimately focus not on mere correlates of awareness, but rather on the neural events that are both necessary and sufficient for perceptual awareness. Indeed, preliminary evidence suggests that although many of the neural correlates already reported may be necessary for the corresponding state of awareness, it is unlikely that they are sufficient for it. The final section considers three hypotheses concerning the possible sufficiency conditions for perceptual awareness. (C) 2001 Elsevier Science B.V. All rights reserved.
