Fig. 6. Box plot of lateralization effects for the activation intensities of (A ) the thalamus, (B ) primary sensomotoric (SI), and (C ) the secondary sensomotoric cortex (SII) in a region of interest analyses. The height of the box characterizes the mean signal intensity in arbitrary units (a.u.), the whiskers the SD. There are no lateralization differences for SI and SII in contrast to the thalamus. Here, the contralateral thalamus is generally strongly activated than the ipsilateral side during and after the incision. *P < 0.05; paired Student t test (see table 4).
