Comparison of label maps from an example subject, each generated from one functional run.

<p>a) Manual stroking. b) Brush stroking. c) Mechanical stimulation. Note the excellent spatial correspondence between the three maps. Although the ‘stroking’ and ‘brush’ runs yield much larger regions above threshold (p<0.001), the label identities in the above-threshold voxels agrees very well. 53% of all voxel in the overlapping region had the same digit label in all three maps; a further 24% of voxels were assigned to an ‘adjacent’ digit in one of the maps (i.e. 2-2-3).
