NEUSleeP System for REM Sleep Enhancement
(NEUSleeP Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a wearable device, the NEUSleeP system, designed to improve REM sleep by using focused ultrasound to target specific brain areas. The main goal is to assess the device's safety and its effects on REM sleep and stress levels. Healthy adults, including those with mild sleep or stress issues, are ideal candidates for this trial. Participants will spend two nights in the study, with the device used on the second night. The results will help determine if this approach can enhance sleep and manage stress. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research on sleep improvement and stress management.
Will I have to stop taking my current medications?
The trial does not require you to stop taking your current psychiatric medications, as long as they have been on a stable dosage and regimen for at least 3 months. Other treatments like therapy or experimental treatments should not be ongoing during the trial.
What prior data suggests that the NEUSleeP system is safe for enhancing REM sleep?
Studies have shown that the NEUSleeP system, which uses a wearable device to improve REM sleep through focused ultrasound, is generally safe and well-tolerated. Research indicates that this system is lightweight and easy to use, making it suitable for everyday use.
The NEUSleeP system has been tested for its effects on REM sleep patterns and stress levels. Initial findings suggest it may be effective without causing significant side effects. So far, studies involving this technology have reported no major negative effects, which is a positive sign for its safety in humans.
The study is labeled as "Not Applicable" for clinical trial phases, indicating that the safety information likely comes from early research rather than large-scale trials. However, the absence of major safety concerns so far is promising for those considering joining the trial.12345Why are researchers excited about this trial?
Researchers are excited about the NEUSleeP system because it offers a novel way to enhance REM sleep, which is crucial for stress relief and overall mental health. Unlike traditional sleep aids that often involve medication, NEUSleeP employs non-invasive brain stimulation technology to precisely target the subthalamic nucleus (STN), potentially improving sleep quality and reducing stress without pharmaceutical intervention. This method could not only provide a drug-free alternative but also offer quicker, more targeted results by directly modulating brain activity during REM sleep.
What evidence suggests that the NEUSleeP system is effective for enhancing REM sleep?
Research has shown that the NEUSleeP system may improve REM sleep. In this trial, participants will divide into different groups to evaluate the system's effectiveness. The NEUSleeP system, a wearable device, uses gentle sound waves to target brain areas involved in REM sleep, potentially increasing both the time spent in this stage and the overall percentage of REM sleep. It may also help users enter REM sleep more quickly. The system is designed to be safe and comfortable, offering a non-invasive way to enhance sleep quality and manage stress.23567

Are You a Good Fit for This Trial?
This trial is for healthy adults aged 18-50 who may or may not have minor sleep or stress issues. Participants will undergo two overnight sessions, with the second night involving a wearable device that aims to influence REM sleep. They must be willing to complete questionnaires and some will have fMRI scans before and after the stimulation.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- NEUSleeP system
Trial Overview
The NEUSleeP system, which records brain activity during sleep and uses ultrasound waves aimed at specific brain areas to potentially enhance REM sleep, is being tested. The study looks at how safe it is and its effect on REM sleep patterns as well as stress levels.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Participants with non-clinical sleep and stress disturbances (PSQI 5-10, PSS 16-21) will undergo baseline overnight EEG/EMG/EOG recording followed by a second night of NEUSleeP-guided FUS stimulation targeting the STN. Pre- and post-intervention fMRI scans and stress questionnaires will assess neural and behavioral effects.
Participants will undergo three phases: (1) NEUSleeP device validation through biweekly EEG and impedance testing over 4 weeks (subset of participants); (2) STN targeting validation using BrainSonix and NEUSleeP with structural MRI and fMRI to assess BOLD response in the STN; and (3) overnight REM sleep modulation with NEUSleeP including EEG/EMG/EOG recordings and pre/post fMRI scans to assess stress-related brain activity and REM sleep outcomes.
