Signal power (ratio) in the leading component in Subject 4. (a) The root-mean-squared (RMS) signal power ${\sigma }_1$ in the principal voxel-wise SHARD component. (b) The total RMS signal power in components 2 to r, i.e., $\sqrt{{{\sum }^{}}_{i=2}^r{\sigma }_i^2}$. (c) The ratio R of the signal power explained in the first component.
