Abstract

Current neuroscience applies a bi-dimensional model to consciousness. Content and level of consciousness have been distinguished from each other in their underlying neuronal mechanisms. This though leaves open the role of the brain's intrinsic activity and its particular temporal and spatial structure in consciousness. I here review and investigate the spatial and temporal features of the brain's intrinsic activity in detail and postulate what I describe as spatiotemporal structure that implies a virtual (e.g., statistically based) spatiotemporal continuity. Such spatiotemporal continuity is supposed to structure and organize the neural processing of the incoming extrinsic stimuli and their potential association with consciousness. I therefore conclude that the current bi-dimensional view of consciousness focusing only on content and level may need to be complemented by a third dimension, the form, e.g., spatiotemporal structure, as provided by the intrinsic activity. In short, I here opt for tri-rather than bi-dimensional view of consciousness.
