Figure 2.

Stimulus-based functional magnetic resonance imaging (fMRI) responses to hand squeezing and tennis playing motor imagery paradigms in healthy subjects. fMRI data are shown as Z-statistic images to demonstrate stimulus-specific responses. Z-Statistic images are thresholded at cluster-corrected Z scores of 3.1 (inset color bars) and superimposed upon T1-weighted axial images. In the row-labeled “ID,” a “+” indicates that an fMRI response was detected and a “−” indicates that an fMRI response was not detected during the hand squeezing and tennis playing motor imagery paradigms, respectively. Abbreviations: F, female; M, male. All images are in radiologic convention.
