Neurofeedback

Neurofeedback or brain biofeedback is used to train the brain to function in a healthier and more normal way, without the use of medication.

Dr. Zukiwski uses two different types of brain biofeedback: biofeedback of the electrical activity of the brain (EEG) and infrared biofeedback.

 

EEG Neurofeedback


Real-time computer based feedback of brain electrical activity can be used to effectively train healthier brainwave wave patterns in children and adults. This training is called neurofeedback, neurotherapy or electroencephalogram biofeedback. One or two electrodes are positioned on the scalp and electrodes are placed on each ear.

Brainwaves are displayed on a computer screen a few thousandths of a second after they occur. Software is used to provide reinforcement – a sound or visual signal – when the right brain frequencies are produced. Through operant conditioning (learning through rewards), brain frequencies that are in excess are reduced, and those with a deficit are increased. As the dyfunctional brain patterns are corrected, the signs and symptoms of the disorder are typically reduced or eliminated.

Children and adults with ADHD can be taught to stabilize the activity at the motor strip of the brain to calm down hyperactivity, take the brain out of an idle state (suppress theta and alpha) and increase normal thinking beta wave activity. Normalizing connectivity between sites in the brain can be effective for treating learning/reading disabilities and epilepsy.

Most conditions require between 10 to 40 sessions to achieve treatment goals. Some clients may require more than 40 sessions. The goal is to achieve improvements that are substantial and enduring. Some clients may require occasional booster sessions, most however do not. Approximately 80% of clients experience significant lasting improvements with neurofeedback.

Passive Infrared Hemoencephalography

Brain biofeedback using infrared sensors has been given a rather long name: hemoencephalography (or HEG for short). There are two types of infrared sensors that can measure the activity of the brain through the skull. Passive infrared HEG measures specific wavelengths of infrared heat that pass through our skin and skull. We can measure the heat generated by blood flow and cellular activity in the brain. Passive infrared HEG was developed as a treatment for migraines. Fortunately, it can be used to treat many other problems associated with weak frontal lobe function: depression, anxiety, ADHD, insomnia, anger, autism, PTSD, and operational stress injury.

HEG training involves watching biofeedback software that displays the changing activity of the brain. The software provides a reward, usually watching a video or DVD, when the brain activity is increasing.

Near Infrared Hemoencephalography

The near infrared HEG device is mounted on a headband that is placed against the scalp. It shines red and infrared light through the skin and skull. A sensor mounted on the headband measures the amount of red and infrared light in a small region of the brain below the headband. Changes in the ratio of red and infrared light indicate changes in brain blood flow and oxygenation. Essentially, the more active the brain, the redder the brain is.
