Summary: much current neurological measurement, e.g., EEG, measures point activity, either activity levels at points in time or activity levels at physical points. Point activity measurement assumes implicitly a "standing wave" model of neural activity, that is, that changes in activity levels at specific points are relevant and indicative of some underlying phenomenon.
More recent research suggests that "travelling waves", i.e., related changes in activity levels at a succession of points, are more indicative of underlying phenomena and that current techniques discard most and almost all of the relevant data. Recording and analyzing more data from more points to reflect related changes in dynamic activity at multiple points, using existing tools, may allow researchers much greater insight into activity correlates to psychological phenomena.
