NeuroLight, a neuromodulation startup, is developing a groundbreaking technology to transplant brain states™ from one person to another using brain entrainment for better sleep, improved cognition, and much more. Brain states include sleep, wakefulness, relaxation, hyperfocus, state of flow, and altered states of consciousness. Some desired states (such as sleep or flow state) are not easy to achieve. NeuroLight developed technology to “transplant” desirable brain states from individuals who already possess them (“donors,” such as healthy sleepers) to other individuals who struggle to achieve them (“recipient”). All brain states are associated with certain brainwave patterns, the rhythmic activity of the brain. Just as music can be recorded and replayed, evidence suggests the brainwaves from one person’s brain—the music of the brain—can likewise be recorded and replayed in another person’s brain. The procedure to transplant brain states involves recording brainwaves in an individual, who is in a desirable brain state and “replaying” these brainwaves in a recipient, thereby inducing the desired brain state. Insomnia is the first problem we are tackling with the anticipated launch of NeuroMask™, which uses pulsating light emitted by the LEDs embedded in the mask and synchronized sound bursts emitted through embedded earphones for brain entrainment to induce sleep. However, our technology has potentially far-reaching applications, including potential treatment of mood disorders, improving concentration and learning, enhancing emotional response in online games and virtual reality, and more.
