The amplitude of the resting-state fMRI global signal
was compared between eyes open (EO) and eyes closed (EC)
states. The amplitude of the global signal was
significantly lower in the EO state and the magnitude of
the decrease was correlated with increases in EEG
vigilance. The relation between the EO-EC changes in
global signal amplitude and EEG vigilance was found to
be similar to that previously observed for
caffeine-related changes in global signal amplitude and
vigilance.
