Abstract
This paper presents a functional brain-imaging strategy designed to isolate neural correlates of consciousness in humans. This strategy is based on skill learning. In the example presented (rapidly generating verbs for visually presented nouns), a cognitive skill is examined before and after practice. As shown, there are marked qualitative differences in the neural circuitry supporting performance of this task in the naive and practised state that include, importantly, both increases and decreases from the baseline activity of the brain.
摘要
本文提出了一种功能性脑成像策略，旨在分离人类意识的神经关联物。该策略基于技能学习。在所举的例子（为视觉呈现的名词快速生成动词）中，一种认知技能在练习前后接受检验。如图所示，在新手状态和熟练状态下，支持该任务表现的神经回路存在明显的质性差异，重要的是，这些差异包括大脑基线活动的增加和减少。
