Primary Outcome Measures

Name	Time	Method
Change in amplitude of evoked potentials metrics as assessed by the scalp EEG	Baseline, post intervention (about 2 hours after baseline )
Change in latencies of evoked potentials and phase synchronization metrics recorded as assessed by the scalp EEG	Baseline, post intervention (about 2 hours after baseline )

Secondary Outcome Measures

Name	Time	Method
Change in reaction time to visual stimuli measured as vigilance score assessed by the Psychomotor Vigilance test (PVT)	Baseline, post intervention (about 2 hours after baseline)	This is a computerized testing that will record errors in being unable to tap a switch/button
