NeuroLight uses light and sound to reproduce optimal brain states — but what are brain states?
We posit that brainwaves are neural correlates of many mental states. Brain states are identified by their brainwave signatures, the unique temporal and spatial patterns of electrical oscillations of neurons in the brain. Characteristic signatures indicate different brain states.
Delta brainwaves are low frequency oscillations that most often occur during deep sleep. When Delta brainwaves are dominant cortical signatures, it is indicative of deep sleep. Delta brainwaves are essential for restoration, rejuvenation, and consolidation of short-term memory into long-term memory.
Theta waves occur in the beginning of sleep cycle, and they indicate of falling asleep.
Alpha brainwaves indicate a person is awake and alert, but doing a restful, thoughtful activity. This could be reading, praying, or relaxing in an awake state. Alpha waves can occur when reading before bed, maintaining a journal, or doing other activities to wind down from the day before sleeping. Alpha waves occur during relaxation or when eyes are closed.
Beta brainwaves occur when working, thinking, doing homework or hobbies that require active attention. Since our waking hours are packed with things that need cognitive attention, creativity and focus, Beta brainwaves are the most common type observed in brain scans.

The science behind imparting complex recorded brainwave patterns with light and sound to reproduce optimal brain states.
A pilot study conducted by NeuroLight in collaboration with the Neuromodulation Lab at The City College of New York seems to confirm the reproduction of sleep states through neuromodulation and brainwave entrainment. Additional studies on sleep and other brain states are currently in progress.
There is a four-step process for reproducing optimal brain states: electrical activity of the brain in a desired state is recorded with electroencephalography (EEG), (2) cortical signatures characteristic of specific brain state are extracted from the recording, (3) these signatures are inverted into a waveform, which is then modulated on light and sound, and (4) the modulated light and sound are used to stimulate the subject who desires to achieve the specific brain state using a NeuroLight NeuroMask™ to achieve brain entrainment.
Our hypothesis is that through brain entrainment, we can reproduced the same cortical signatures and, ultimately, the same brain state as in the donor. The science supporting this simple process, however, is revolutionary.
NeuroLight’s technology works by combining the neuromodulation and the principles of brain entrainment. What makes NeuroLight unique is the use of recorded brainwave signatures from actual individuals to reproduce brain states. By applying the targeted stimulation of neuromodulation to entrain — or naturally synchronize — a person’s brainwaves with those of a recorded brain state, either from the same individual or another person.
Other neuromodulation devices use simplified, synthesized frequencies. But by using naturally occurring, complex frequencies recorded during the desired brain state, NeuroLight may be more effective at reproducing those states.
