Neurophysiological Indicators of Residual Cognitive Capacity in the Minimally Conscious State

Figure 5

Individual patients considered responders in the active counting condition of task 2. (a) Illustrates ERPs in individual MCS+ responders in task 2, while (b) provides ERPs in individual MCS− responders. The averaged ERPs in the active counting (red) versus passive (black) condition (-axis, amplitude in μV; -axis, time in ms) are illustrated. Observed significant differences of P3 amplitude between conditions ( values < .05 to .001) are marked with a star above the P3 curve marked with grey line.
