Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to look at the effects of targeted brain stimulation when falling asleep and on sleep quality.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to see the effects of targeted brain stimulation when falling asleep and on sleep quality. The study uses non-invasive Transcranial Electrical Stimulation (tES), and/or a standard electroencephalogram (EEG). We may also measure eye movements, muscle activity, and heart rhythm. We may play audio during the stimulation.

The sessions can include full overnight sleep or short nap session.
