Global workspace model of consciousness and its electromagnetic correlates
Annals of Indian Academy of Neurology July 1, 2008 Ravi Prakash, Om Prakash, Shashi Prakash et al.
The global workspace of consciousness, first proposed by Baars in 1982, describes how information becomes globally available in the brain, but its origin and mechanism remain poorly understood. One underexplored candidate is the brain's electromagnetic field. This review examines the theoretical framework and neuroimaging evidence for the global workspace model, then turns to electromagnetic field theories of consciousness. It highlights electromagnetic correlates derived from these theories that may underlie the global access phenomenon, suggesting that electromagnetic fields could play a key role in conscious awareness.
