When the brain doesn’t switch off even at night — what can Agytréner do?

Nearly a third of Hungarian adults struggle with chronic sleep problems. After the fourth sleepless night, cognitive performance visibly declines, the immune system weakens, and the stress threshold drops. The Agytréner system — and in particular the audiovisual entrainment technology it employs — offers concrete, measurable tools for this problem as well.

Sleep as the silent crisis of the modern age

According to a 2024 domestic survey, 46 percent of Hungarians have difficulty falling asleep — this ratio was still 31 percent four years earlier. The proportion of adults with severe sleep problems, meaning those who wake up repeatedly during the night and rise unrested, has also surged: from a previous 16 percent to nearly 29 percent today.1 Out of a hundred people, only two actually wake up truly rested.

Behind these numbers lie concrete physiological processes. Under prolonged stress, the proportion of deep sleep decreases significantly — this can be well documented even with wrist-worn sleep trackers. The amount of sleep is important, but the quality of sleep is at least as decisive: it doesn’t matter if someone spends 8 hours in bed if only a small portion of that is spent in a deep, restorative phase.

At presentations, Agytréner experts repeatedly emphasize: some kind of regulatory disturbance usually underlies sleep disorders. Persistently elevated stress states in the brain, disruption of the autonomic nervous system’s balance, cortical activation getting stuck at a high level — all of these impair falling asleep and the attainability of deep sleep. The good news: these processes are measurable and can be influenced.

Brainwaves and sleep — what actually happens?

At every moment, the brain generates electrical waves that show characteristic frequency patterns. In the waking state, the beta range (13–25 Hz) dominates; during relaxation and contemplation, alpha (7–13 Hz) comes to the fore; in the transitional phase before falling asleep, theta (4–7 Hz) takes over, and finally in deep sleep, delta (0.5–4 Hz) takes control.

In the brains of people struggling with sleep — especially those whose “mind races” after lying down — high frontal beta activity can typically be detected at night, while the body already wants to rest. Since Peter Hauri’s early neurofeedback research, we’ve known that this pattern can be specifically altered.

Audiovisual entrainment (AVE) — the main technology of the brain-training device — builds precisely on this mechanism. Rhythmically pulsing light and sound stimuli reach the cerebral cortex via the thalamus, where, through the frequency-following response, brainwaves tend to synchronize to the frequency of the stimulus.

Brainwave ranges and sleep

Beta (13–25 Hz)
Waking focus, stress, anxiety. High levels before sleep cause difficulty falling asleep.

Alpha (7–13 Hz)
Relaxation, meditation, closing the eyes. The gateway to falling asleep.

Theta (4–7 Hz)
Dream-like transition, the antechamber of REM sleep. Difficult to sustain while awake.

Delta (0.5–4 Hz)
Deep sleep, regeneration. Its absence causes fatigue and weakened immunity.

How does Agytréner affect sleep? — five pathways

„Nothing calms an irritated amygdala and hypothalamus as effectively as alpha-range AVE.”

What sleep-support programs exist in the Agytréner system?

The brain-training device includes program types specifically designed for sleep, which are incorporated into the training plan based on the client’s individual profile — qEEG, HRV, cognitive test, and visual response.

Program name Frequency Recommended for whom? Main effect
SMR for Sleep 14 Hz “Racing mind” insomniac, with a relaxed body Increasing SMR slows down somatomotor activity
Extended Schumann Resonance 7.8 Hz Anxious and tense sleep difficulty, disrupted circadian rhythm Maximum increase in cerebral blood flow, deepening mental silence
Alpha/Theta 6–10 Hz Racing thoughts, pre-sleep anxiety Dream-like transitional state, deep relaxation
Meditate to Sleep 8 → 3 Hz Anxious, pain-affected sleep-deprived individual Gradual descent down to delta, initiating sleep
Delta Sleep 3.5 Hz Fibromyalgia sufferer, struggling with chronic pain Direct stimulation of the deep sleep phase

What does the research say?

♦ Research

Hauri’s neurofeedback studies — SMR and insomnia

Peter Hauri demonstrated that upward training of the sensorimotor rhythm (SMR, 12–15 Hz) with neurofeedback dramatically improves the “racing mind, relaxed body” type of insomnia. AVE research adapted this protocol to optical and audio stimuli, and documented similar results.

Result: significant improvement in sleep onset latency and sleep quality — especially in anxious insomniacs with tense posture.

♦ Research

Berg & Siever (1999) — fibromyalgia and sleep

Among fibromyalgia patients (n = 66), the combined effect of AVE treatment and supplements was measured. Delta and alpha programs reduced pain perception and improved sleep depth — delta stimulation proved particularly effective where the deep sleep phase was deficient.

Result: reduced pain intensity and improving sleep quality compared to the control group.

♦ Research

BrainTap pilot study (2022) — 6-week AVE program

20-minute AVE programs three times weekly for 6 weeks (binaural beats, isochronic tones and LED light, stepped down from 18 Hz to 0.5 Hz). Sleep quality measurement tool: Pittsburgh Sleep Quality Index (PSQI).

Result: significantly improving sleep quality (PSQI, p<0.05); participants described the program as extremely relaxing.

♦ Research

Halpin et al. (2023, Frontiers) — alpha entrainment for sleep and pain

28 adults (79% women, average age 45) spent 30 minutes daily before sleep for 4 weeks with 10 Hz alpha entrainment. The study was registered under ClinicalTrials.gov number NCT04176861.

Result: improving sleep quality and reduced nighttime pain intensity — an age group especially relevant for the domestic target audience.

The role of measurement: why isn’t training alone enough?

A distinctive feature of the Agytréner system is that treatment precedes training. During the assessment phase, a qEEG examination, HRV measurement, cognitive tests, and analysis of the visual responses triggered by the brain-training device are carried out. This complex picture reveals exactly which brain pattern the sleep disturbance is linked to.

One person struggles with elevated frontal beta activity at bedtime. In another case, the alpha peak frequency has slowed below normal, which results in a daytime “brain fog” sensation and also worsens nighttime sleep quality. In yet another case, HRV values indicate an imbalance in the autonomic nervous system.

The qEEG-based personalization allows the 6-week training program to be based not on a generic recipe but on the individual’s own brain and physiological profile. At the end of the first cycle, a re-measurement follows, and the program is fine-tuned based on the changes revealed.

How is the 6-week Agytréner cycle structured?

Agytréner training is not a one-time session but a structured development process. The first step is always the assessment, the result of which is a personalized, 6-week training plan. In the case of sleep problems, this typically includes evening AVE programs, HRV breathing exercises, and — where the individual profile warrants it — supplementary daytime activating programs.

Weeks 1–2

Assessment and foundation

qEEG, HRV, cognitive test and analysis of visual response. The first programs focus on tuning the nervous system: reducing stress reactivity, improving breathing patterns.

Weeks 3–4

Targeted sleep support

Regular application of the sleep protocol selected based on assessment data. Most clients experience the first meaningful changes in falling asleep and the number of nighttime awakenings during this phase.

Weeks 5–6

Consolidation and follow-up measurement

Consolidation of the established nervous system patterns. At the end of the cycle, another measurement shows the changes in brain activity and HRV — this forms the basis for the next 6-week plan.

The role of color and music in sleep support

An additional layer of the brain-training system is the application of various color and music stimuli. The blue light of the AVE glasses is the classic choice for meditation and sleep support — physiologically it lowers blood pressure, regulates sleep patterns and thyroid function, and psychologically it increases the sense of calm and inner peace.

In terms of music, research recommends the slow movements of symphonic pieces for those struggling with sleep disorders: the first movement of Beethoven’s Moonlight Sonata, the steady, meditative rhythm of Bach’s harpsichord pieces, Schumann’s Träumerei. These are not merely pleasant background sounds — their sound patterns, tempo (generally around 60 bpm) and dynamics exert a direct physiological effect on breathing, heart rhythm and cortisol levels.
