a) Confusion matrices for a 7-way linear classifier using neural responses. AUD electrodes (top panel). PROD electrodes (middle panel). S-M electrodes (bottom panel). Performance is thresholded at chance performance, p = 0.14, for display purposes only. b) Classification performance for increasing numbers of electrodes. Chance performance (dotted). c) Classification performance for S-M electrodes in the left (dark red) and right (light red) hemispheres. Chance performance (dotted). Online Methods presents S-M results by response epoch.
