It can be argued that the estimated activity correlates with the underlying neural activity to a certain, limited, extent, but the true underlying neural activity creating the magnetic fields observed in the MEG can not be visualized 1 to 1. From the same data we can get different visualizations of the brain's activity using different thresholds. When the threshold is set low, it is more probable that the source estimate visualization highlights also some areas of the brain where no significant change in the true neural activity was actually present. On the other hand, when the
