Audio stimulation of slow-wave sleep enhances brain function.

Neural function, i.e. how well the brain communicates its messages across the brain and body, impacts brain health, physical restoration, mental health and more. The negative impact of slow-wave sleep (SWS) deprivation on memory, cognitive performance, and mood is well-established — which raises the question, can SWS be enhanced to improve cognition, physical performance and mental health? NeuroGevity system does exactly this — it provides audio stimulation to entrain slow-wave brain signals thereby enhancing SWS and cognitive function.

Adults typically have 4-5 sleep cycles during the night, each lasting ~90 minutes. Each cycle rotates through the various stages of sleep: rapid eye movement (REM), light sleep and slow-wave sleep (SWS), also called delta or deep sleep. Of these stages, SWS plays a key role in memory, physical recovery, hormone activation and balancing the parasympathetic-sympathetic systems for emotional regulation. Therefore, SWS has a profound effect on health and well-being.

Take memory for example. During SWS, information is transferred from short-term storage in the hippocampus to long-term storage in the neocortex. This transfer is orchestrated by Slow Oscillations (SOs), special brain waves which carry information throughout the brain. The number and strength of these SOs determines how much information is transferred to your brain’s “hard drive”. SO activity steadily declines as we age. A typical 20-year-old has approximately 1,000 SOs during the night, but by the time you are 80 years old, you typically have only 100 of these memory consolidation events each night. This is the natural aging process, and why our ability to remember declines as we age.  

NeuroGevity detects and stimulates these SOs – synchronizing sound to your brain’s natural frequencies – to enhance the brain activity responsible for preserving and strengthening memories. Like an audio pacemaker, this stimulus activates the memory consolidation brainwaves and keeps them functioning. Our NeuroGevity system has been studied in several university-based trials demonstrating enhanced SWS activity and increased memory recall. Several more trials are underway to measure impact on SWS enhancement on hormone levels and executive function.

AUDIO STIMULATION

NeuroGevity applies state-of-art research to enhance and strengthen slow-wave sleep by synchronizing an audio stimulation to the user’s natural brainwave frequency. This amplifies the brain signals and induces additional signals.

The benefits of audio stimulation of slow-wave sleep has been well established.

NeuroGevity has been used in several IRB-approved university-based studies, and three more trials are scheduled for early 2024. Early results demonstrate strong improvement in neurophysiology and increase in both memory recall and generalized learning.
