Blog & Learn: Sound Science for Sleep, Focus, and Therapeutic Wellbeing
Palatone · Neurosonos · Updated 2026-08-10
The Palatone blog is a small set of in-depth, citation-supported explainers on the sound-science research behind the app. Each anchor below links to a long-form post — and each post links back here. Together they form the publishing hub for the five most-cited scientific threads behind Palatone's audio engine: binaural beats, 40 Hz gamma entrainment and the MIT GENUS protocol, the 40 Hz × Alzheimer's × sleep cross-condition research line, delta-band deep-sleep entrainment, and theta-band focus and creativity entrainment.
Anchor articles
Binaural Beats: What They Are, How They Work, and What the Research Shows
A plain-language overview of binaural beats — the two-tone frequency-difference illusion created by slightly different pure tones in each ear — and what the published research shows across theta, alpha, beta, and gamma bands for sleep, focus, anxiety, ADHD, and chronic pain.
40 Hz Sound Therapy: What It Is, How It Works, and the Research Behind It
The MIT Tsai Lab's GENUS protocol, gamma entrainment via precisely timed 40 Hz audio, and the published evidence supporting clinical research in Alzheimer's, sleep, focus, anxiety, ADHD, pain, and Parkinson's.
40 Hz Gamma, Alzheimer's, and Sleep: The Cross-Condition Research Line
The detailed cross-condition research link between 40 Hz gamma-band stimulation, Alzheimer's-disease pathology, and AD-related sleep disruption — and why the audio channel of the GENUS protocol matters for sleep-stage work.
Delta Waves and Deep Sleep: How 0.5–4 Hz Entrainment Works
Delta-band (0.5–4 Hz) auditory entrainment, slow-wave sleep physiology (SWS, K-complexes, sleep spindles), and the published evidence for sub-4 Hz frequency-following response as a non-pharmacological sleep cue — including the 40 Hz gamma-band handoff.
Theta Waves for Focus and Creativity: How 4–8 Hz Entrainment Works
Theta-band (4–8 Hz) auditory entrainment, the link between theta oscillations and hippocampal memory encoding, the hypnagogic and light-meditation use cases, and the published evidence base for theta-band stimulation as a focus, creativity, and ADHD-adjacent attention cue — including the delta-band sleep handoff.
How to read these
The anchors are written to be read in any order. New to the field, start with the binaural beats overview — it covers the frequency-following response, the band-by-band evidence base, and the safety callouts that apply across all five posts. If you're focused on clinical or therapeutic applications, jump to 40 Hz sound therapy, then the Alzheimer's → sleep cross-condition line. If sleep is the primary interest, the delta-waves post closes the loop; if focus and creativity are the primary interest, the theta-waves post covers that band.
