The finding of discrete time frames or modes was explored further by correlating the Euclidean distance of the Talarich atlas coordinates of the DMN (i.e., square root of the sum of squares of x + y + z) with phase shift and lock duration. Figure 5 are the results of regression analyses in which statistically significant inverse relationships were present between phase shift vs. phase lock duration. That is, phase shift duration tended to be short when Brodmann areas were closer together and lengthened as the distance between Brodmann areas increased. In contrast, phase lock duration tended to be long when Brodmann areas were closer together and short when Brodmann areas were more distant.
