Results of the auditory stimulation test in patient 4. In a total of 92 ON windows, 590 stimulations were delivered. (A) Average +/- standard error of the mean of power density (dB from − 20 to 30, 0 dB = 1 µV²/Hz) in ON-windows and in OFF-windows. Power density did not differ between ON- and OFF-windows in any of the frequency bins (unpaired t-tests, all P > .05). (B) Phase distribution of all stimulations in ON-windows. Circular mean was at 66.2 degrees (standard error of the mean = 1.8). (C) Heart rate (dark grey) and intracranial pressure (light grey) before, during (rectangle), and after the stimulation phase
