Figure 4.

Maps of largest variance component (excluding ${\mathrm{\sigma }}_{\text{err}}^2$) for the three subjects under evaluation. Green signal voxels where ${\mathrm{\sigma }}_{\text{session}}^2$ was the largest. Red signal voxels where ${\mathrm{\sigma }}_{\text{run}}^2$ was the largest. Finally, blue signal voxels were ${\mathrm{\sigma }}_{\text{block}}^2$ was the largest. Maps are restricted to significantly grey matter active voxels.
