Phase-Locked Stimulation
Sound only works when timed to the brain.
Researchers played sound pulses two ways: timed to the brain's slow waves, and at random. Only the timed pulses strengthened deep sleep.

The Research
10 years of research.
Pioneered at leading sleep labs.
One breakthrough.
In sleep labs around the world, researchers have shown that precisely timed sound pulses, delivered during deep sleep, can measurably strengthen slow-wave activity. The effect has been observed across multiple independent research groups.

Our Technology
Closed-Loop Auditory Stimulation
Neurex reads your brain's electrical activity in real time. When it detects deep sleep, it delivers precisely timed sound pulses that synchronize with your slow waves, strengthening the sleep that matters most.
Real-Time EEG Detection
⌄
Dry EEG sensors in the headband continuously monitor your brainwave activity. The system identifies when you enter deep sleep by detecting slow oscillations, the neural signature of restorative rest.
Precision Sound Pulses
⌄
Short, gentle audio tones are delivered through bone conduction at the exact phase of each slow wave. This timing is critical, pulses must land within milliseconds of the wave's peak to amplify deep sleep.
Adaptive Algorithms
⌄
Neurex learns your unique sleep architecture night after night. The algorithm adjusts pulse timing, volume, and frequency based on how your brain responds, getting more effective with every use.
Built on Published Neuroscience Research
Peer-reviewed research has explored how closed-loop auditory stimulation interacts with deep sleep brainwaves.
Peer-Reviewed Science
Reviewed in leading neuroscience journals.
A 2026 Frontiers in Neuroscience review by Johns Hopkins researchers examined closed-loop auditory stimulation as an emerging approach to strengthening deep sleep.
Smart Sleep Technology
The More You Use Neurex, The Better It Gets
Your first nights calibrate the system, mapping your unique brainwave patterns and sleep architecture. From there, Neurex builds a personalized stimulation profile that evolves with you. No two brains are the same, and neither is your Neurex experience.
