Brain Stimulation and the Threshold of Conscious Experience

  • Chapter
Brain and Conscious Experience

Abstract

The subject of this paper stems out of a more general question which asks, what is the spatiotemporal configuration of neuronal activity which effectively elicits or is at least uniquely correlated with a conscious awareness of something? Now, to attempt a study of whole configurations of neuronal activities is obviously much too difficult and complicated. One would like to delimit severely the experimental approach to this question, and this we have done in two ways.
