Figure 6. Reduced activations in affected forepaw.
Cortical activation maps for electrical forelimb stimulation of left (unaffected) forepaw (top row) and right (injured) forepaw (bottom row). The right limb exhibits reduced response amplitude as a function of stroke severity (see Fig. S3), while the induced response in the unaffected left limb is similar to the control group. Pixels having a response amplitude within 75% of maximum response are overlaid on a representative white light image of the brain.
