Figure 1.

Plasticity in motor cortical activation patterns across observational periods reveals shifts in the contralateral motor cortex (MC) and disengagement of ipsilateral motor cortical regions. This figure shows average motor activation (thresholded at full-width-at-half-maximum) at first (left columns) and second (middle column) timepoint, respectively, in patients with frontal-insular-temporal tumors. Also, statistically significant changes in activation patterns (first minus second time point; blue areas indicate decreased activation at second timepoint) are shown (right column, p < 0.05 with a cluster threshold of 20 voxels). Rows indicate different tumor locations. Activation during both the left index finger (A) and right index finger (B) motor task is shown.
