Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Difference in EEG slow wave amplitude from anti-phase to in-phase stimulation
Difference in EEG slow wave amplitude from sham to in-phase stimulation
Difference in EEG slow wave duration from anti-phase to in-phase stimulation
+1 more
Secondary study objectives
Change in slow wave activity on the night of the intervention will be compared to that on the night prior to the study session.
Difference of reactivity to thermal stimulation from anti-phase to in-phase stimulation
