The neural correlates of consciousness: an analysis of cognitive skill learning
Philosophical Transactions of the Royal Society B Biological Sciences November 29, 1998 M. E. Raichle 130 citations
A brain-imaging strategy isolates neural correlates of consciousness by examining a cognitive skill—generating verbs for visually presented nouns—before and after practice. Marked qualitative differences in neural circuitry appear between naive and practised states, including both increases and decreases from baseline brain activity.
