Summary
AI-generated from the abstractEvidence from fMRI, MEG, and EEG recordings shows a neural signal occurring about 200 milliseconds after a stimulus appears, located mainly in parietal and extra-striate visual areas, which appears to be a copy of the command that shifts attention. This signal, termed a corollary discharge of attention movement, is observed before subjects report their conscious experience. The authors suggest this finding offers a promising path for investigating the link between attention control signals and human consciousness.

Abstract
We discuss experimental support for the existence of a corollary discharge signal of attention movement control and its formulation in terms of the corollary discharge of attention model of attention movement (CODAM). The data is from fMRI, MEG and EEG activity observed about 200 ms after stimulus onset in various attention paradigms and in which the activity is mainly sited in parietal and extra-striate visual areas. Moreover the data arises from neural activity observed before report of a subject's experience occurs. The overall experimental support for the existence of a copy of the attention movement control signal generates, it is suggested, a viable route to explore the relation between this signal and human consciousness, as concluded in the paper.
