did TMS to healthy patients when awake and in NREM as well as under anesthesia.
did TMS to patients with loss of consciousness

Question 6

results of the paper for healthy people

Answer 6

activation was widespread and differentiated across brain in wkefulnes, PCI high
activation was localized and short lasting in NREM, PCI low

Question 7

results of the paper for non healthy people

Answer 7

vegetative: within NREM (PCI low)
locked in/ could comm w eye blinks: PCI high
minimally conscious states: above NREM range

Question 8

PCI scores from lowes to highest

Answer 8

vegetative state -> minimally conscious and emerging from minimally conscious -> LIS
