Figure 1. Thresholded t-maps for hand activation.
A: Hand gestures used for this study. These gestures were chosen for maximum mutual differences in flexion-extension combinations. B: Activation for right/phantom hand. C: Activation for left/intact hand. The contrast used for this image was ‘8’+‘F’+‘L’+‘S’+‘W’+‘Y’>baseline. In all subjects, there is clear activation inside the contralateral central sulcus, which is associated with hand control. T-values are set per subject for visualization purposes. Images are in neurological orientation.
