Very simply put, neurofeedback (or eeg biofeedback) is the science of reconditioning and retraining brain wave patterns. Although still considered “new,” this learning technique has been widely used since the 1960s for stress reduction and the treatment of epilepsy. Mirasol pioneered the use of neurofeedback in the treatment of eating disorders and is a center for research on the use of neurofeedback as an alternative to psychotropic medications.

Eating disorders don’t exist in a vacuum. They often occur in conjunction with other conditions such OCD, anxiety, depression and sleep disorders. These collateral disorders are very easily and successfully treated with EEG.

All Mirasol clients receive a brain map during their first few days of treatment. The brain map pinpoints the area of the brain and the bandwidth of brain wave deviations.

During typical neurofeedback training, sensors are placed on the scalp and/or ear lobes. An eeg unit provides instantaneous audio and visual display of brain wave activity. This “feedback” allows the individual to influence and change brain activity. Through individualized neurofeedback training, the brain learns to increase or decrease certain frequencies in order to function most efficiently for the task at hand. The changes are temporary at first but become permanent over time.
An EEG, or electroencephalogram, is a recording of electrical activity in the brain using sensors (electrodes) on the scalp. The presence of different brain frequencies was first demonstrated by the German psychiatrist Hans Berger in 1929. The EEG has long been a valuable tool of neurologists in the diagnosis of epilepsy and other brain disorders.

What is EEG Biofeedback?
This is a learning technique by which the brain improves its function by receiving information about the frequencies it is creating. Dr. Barry Sterman, UCLA professor emeritus of neurology and psychology, pioneered this area of operant conditioning while doing animal research in the 1960s. In the decade before, experiments by psychologist Joe Kamiya, Ph.D., at the University of Chicago showed that brain waves were not totally involuntary as had been thought. The brain can be nudged to produce more or less of a certain frequency by the simple feedback of audio tones, for example. Also known as Neurofeedback, EEG Biofeedback enhances the brain’s communication network in a painless and noninvasive way. In some cases, it can reduce a client’s need for medication. The field of EEG Biofeedback has grown rapidly and internationally since the 1980s. Its practioners include neurologists, psychiatrists, psychologists, and counselors.
EEG Biofeedback was first applied as a tool in managing epilepsy, Attention Deficit Disorder, and Attention Deficit Hyperactivity Disorder. Today this learning technique is employed to treat a wide variety of conditions, including brain injury, depression, anxiety, and disordered eating. The broad application of EEG Biofeedback stems from its support of the innate regulatory function of the brain. Supported by current research, Mirasol approaches eating disorders as chronic stress-related conditions. They begin as an individual’s adaptation to stress, and subsequently gain increased control over a person’s life and choices. Stress chemicals have detrimental physiologic affects on brain structure and function. We also know that the developing brain is positively impacted by emotional nurturing in childhood. EEG Biofeedback is a valuable complement to other stress reduction therapies at Mirasol. It supports the formation of the brain’s essential communication pathways and helps clients live more effectively with a variety of emotions. Commitment to balanced nutrition that includes complex carbohydrates is necessary for a client to reap the maximum benefit from neurofeedback therapy.

What occurs during EEG Biofeedback training?
Sensors on the scalp pick up information about the waves of electrical energy the brain is producing. A computer amplifies these complex signals and displays them on the monitor as small groups of energy at specific frequencies. This information is “fed back” to the client, often through audio tones. Some training involves the use of computer games like mazes or space race. Protocols using the electrode cap, developed by Marvin Sams, N.D., do not depend upon a client’s conscious effort to control brain patterns. This novel form of neurofeedback provides audio reinforcement to the brain when performing a task that requires attention and concentration, such a playing tetris. Mirasol is one of three places in the United States that offers EEG Biofeedback training with the electrode cap.
Beta rhythms reflect “fast” activity-frequencies activated when we are alert, problem solving, or being anxious. Rapid consolidation of information produces frequencies in the highest range, known as Gamma. Alpha rhythms are the most frequent wave patterns, and they occur when we are relaxed and detached. When we close our eyes and begin to feel drowsy, the brain produces Alpha. Theta frequencies reflect even deeper relaxation, occurring as we slip closer to sleep and form mini-dreams or images. The brain during deep sleep produces the slowest waves, known as Delta. Through training, the brain learns to increase or decrease certain frequencies so that it is functioning in the optimal way for the task at hand. EEG biofeedback produces greater efficiency and flexibility as the brain moves between different states. The stress of living in today’s culture produces particular wear on the nervous system, but we now know that we can play a role in balancing this stress. Problems of brain self-regulation fall into three general areas: instability (which is the case in epilepsy and other conditions), under arousal, and over arousal. Training Beta activity is often selected to treat manifestations of under arousal such as depression, poor attentional focus, and frequent awakenings at night. Symptoms of over arousal, such as anxiety and difficulty falling asleep, commonly respond to training in a frequency just lower than Beta, called SMR. Alpha training is appropriate for some individuals with anxiety because of its calming effects. Deep relaxation training with alpha-theta brain wave feedback has been used to successfully treat addictions.
