Before revision:  These results support the conclusion that FOBP is an objective measure of vigilance in healthy human subjects.
After revision:  Discussion: In this study, we investigated whether simultaneous EEG-fMRI combined with eye-tracker measurements can be used to determine EEG signal feature associated with vigilance measures during eyes-open rsfMRI. Our results support the conclusion that FOBP is an objective measure of vigilance in healthy human subjects.
