Neuronal discharge rate and muscle activity collected during one trial of the reach/button press task. Behavioral phases are indicated by the lowest set of traces. Center LED indicates the time at which the center button was lighted. Center button and Outer button indicate center and outer button presses, respectively. The decreased activity during reach, and the phasic-tonic bursts associated with the button presses are seen in the simple spike discharge and the EMGs of several muscles, most notably flexor pollicis brevis.
