Classification performance. A. Performance for four‐way classification (right hand, left hand, right foot, and left foot). The mean performance of the classifier when classifying single trials in a scan series not used for training, averaged across eight subjects (error bars shows the SEM). The gray bar shows the performance when the classifier was trained and tested on voxels in all ROIs; colored bars show performance when classifier was trained and tested only on voxels in a single ROI (S1, S2, MST/STP). Chance performance was 25% (dashed line). B. Accuracy of two‐way classification (left hand vs. right) in three ROIs. C. Accuracy of two‐way classification (left foot vs. right foot) in three ROIs. D. Accuracy of three‐way classification in experiment 2 (thumb vs. middle finger vs. pinky finger). [Color figure can be viewed in the online issue, which is available at www.interscience.wiley.com.]
