What is EEG biofeedback?

EEG (electroencephalography) biofeedback, also called neurofeedback, is a brain training method based on measuring and visualizing brain waves. It allows patients to learn self-regulation of brain activity through real-time feedback.

How does neurofeedback work?

During a session, electrodes are placed on the patient's head to record the brain's electrical activity. These signals are processed by a computer and presented as a game or animation. When the brain produces desired wave patterns, the patient receives positive feedback (e.g., game progress, pleasant sound).

What brain waves do we measure?

  • Delta (0.5-4 Hz) - deep sleep, regeneration
  • Theta (4-8 Hz) - relaxation, meditation, creativity
  • Alpha (8-12 Hz) - calm wakefulness, relaxation
  • Beta (12-30 Hz) - concentration, mental activity
  • Gamma (30+ Hz) - information processing, memory
  • Who is neurofeedback for?

    EEG biofeedback is particularly effective for:

  • ADHD in children and adults
  • Concentration and attention problems
  • Anxiety and depression
  • Insomnia
  • Migraines
  • Stress and burnout
  • Is biofeedback safe?

    Yes, EEG biofeedback is completely safe and non-invasive. We don't use any medications or electricity - we only measure natural brain signals. The method has no side effects and can be used on children from 5 years of age.

    How many sessions do I need?

    A typical therapy cycle includes 20-40 sessions, depending on the problem and individual patient response. Sessions take place 2-3 times a week and last about 45-50 minutes.

    Are the effects permanent?

    Yes, one of the greatest advantages of neurofeedback is the permanence of effects. After completing therapy, the brain retains the learned patterns. Studies show that effects persist for years.
