This study extends the investigation of the spatial and temporal properties of the scalp surface EEG PR to the current sources of the EEG. There was an approximate seven year age range of subjects in this study, however, no significant correlations with age were present. A new finding is discrete temporal modes of phase shift and phase lock duration that are unique for different Brodmann area associations of the DMN. A second finding is significantly greater complexity and higher dimensionality of phase shift duration in comparison to phase lock duration, i.e., a temporal dimension reduction from phase shift to phase lock duration. A third finding is an inverse relationship between spatial distance between Brodmann areas and PR metrics where short distances are exponentially related to long phase lock durations and short phase shift duration, whereas, long distances are exponentially related to long phase shift durations and short phase lock duration. Overall, the findings are consistent with previous studies demonstrating that temporal “frames” or “chunks” are discrete and different for different Brodmann areas of the human brain. The results can be
