From: Brain imaging reveals covert consciousness during behavioral unresponsiveness induced by propofol
Time-locked and delayed brain responses during mental imagery tasks. To assess the effect of possible response time delay as a function condition, the events’ timing was shifted backward and forward up to −32 s (40 TRs; TR = 0.8 s) and +32 s in steps of 0.8 s (1 TR) centered on the instruction onset (0 s). The curves represent the estimated activation changing as a function of time shift shown for the ROIs of each imagery task across five sessions (Base1, PreLOR, LOR, ROR, and Base2). Results for subject P01 with saline (no propofol administration) served as a control. Note that the session segmentations of P01 were taken from that of P04, so that P01 was always responding.
