Recent findings from functional MRI scans (fMRI) and magnetoencephalography (MEG) have suggested the angular gyrus, a region of the brain known to be involved in language, number processing and spatial cognition, memory retrieval and attention, as a potential hub for semantic memory integration, specifically the left angular gyrus.

Studies using magnetoencephalography (MEG) (10) suggest that during REM sleep the nervous system is processing its own intrinsic neuronal information which creates a form of internal consciousness when we dream, while during waking hours it receives sensory information from the outside world which processes and modifies neuronal rhythms, creating a state of awareness--the SELF.
