Frequency training is the most established form of neurofeedback.
How does it work?
It works by seeking to inhibit certain brainwave frequencies while reinforcing others in order to reach optimal brain functioning. For example, training a frequency of 12 to 15 Hz EEG in the sensory motor cortex can help control epilepsy and seizures.
During neurofeedback sessions, the client’s brainwaves and energy state are measured in real-time, and feedback is provided in the form of sound and visual cues, indicating whether the desired frequencies were produced or not.
What are the benefits?
Once a client progressively learns to produce the desired frequencies and state, long-lasting change can be seen.
There has been extensive research done using frequency on the effect of neurofeedback for a wide range of disorders (please see NF Benefits for research).
What’s the process?
During an initial session, the practitioner will interview the client regarding their symptoms and goals. Practitioners will later often conduct a QEEG assessment (brain map) where they map the client’s brain activity whilst the client is wearing a multi-electrode cap. Practitioners can also analyse the client’s EEG data and compare the results to a pre-established ‘norm’ to determine how to best proceed with treatment.
During follow-up sessions, neurofeedback training will be conducted whilst the client is watching a program. Each follow-up session is 45-60 minutes in length, 2-3 follow-up sessions a week are usually recommended, and on average 40 follow-up sessions are required.
