An Alternative or Adjunct to Medication:

We have successfully used Quantitative EEG and neurofeedback in modalities for the enhancement of CNS (Central Nervous System) functioning. Neurofeedback allows for improvement in brain function based on or central nervous system functioning (feedback) in order to improve some or many aspects of the persons physiological function. Through the modality of neurotherapy, Siber Imaging offers specialized training protocols (developed and patented by Dr. Myra Preston and Kimberly Phillips) to rehabilitate clients.


Why We Are Unique

Dr. Myra Preston, Ph.D., has been the only Neurophysiologist in private practice serving the Charlotte community since 1984. All QEEGs are interpreted in-home and all protocols are established in-home. We do not outsource our work. Siber Imaging was created in 1993 with the intention of providing therapy to our clients here in Charlotte as well as across the country and internationally. Siber Imaging was founded by Dr. Myra Preston and Kim Phillips, Clinical Director.  



Areas of Practice

QEEG (Brain Mapping)

Quantitative EEG (qEEG) is a non-invasive measurement, using digital technology, of electrical patterns at the surface of the scalp which primarily reflect cortical electrical activity or “brainwaves.”


Neurotherapy (also known as neurofeedback and EEG feedback), first introduced in 1957, is a specialized form of biofeedback. Biofeedback utilizes behavior change in conjunction with regulation of one’s own physiology.

US Patent Information

Dr. Myra A. Preston “METHOD OF DIAGNOSING AND TREATING CHRONIC FATIGUE SYNDROME” United States Patent No. 5,267,570 Issued December 1993.



Myra A. Preston, PhD holds doctoral degrees in both Psychophysiology and Neurophysiology. Dr. Preston is neither a medical doctor nor a clinical psychologist. The field of Neurotherapy is one governed by a National Board Certification and a National Licensure. Dr. Preston has held these credentials since 1982. In our facility we do not diagnose or treat any condition. We work in association with licensed medical doctors. Our clinic operates in strict accordance with the appropriate standard of care consistent with N.C. statutes 90-18 and 90-14.12.



The Neurofeedback/QEEG process

The first step in understanding how an individual may be struggling cognitively, physically, or mentally is to acquire a QEEG (quantitative EEG) assessment. This is a non-invasive test which is performed by playing a cap over the scalp and acquiring raw data in the eyes closed and eyes open position. Dr. Preston analyzes the data and removes any artifact. The data is then put through a normative data base and analyzed by Dr. Preston. With this advanced state of the art technology, we can determine the regions of the brain operating effectively and regions under firing or over firing. This data is then broken down into Brodman areas.  Brodman areas outline regions of dysfunction and symptoms of defect.  Three dimensional  displays of the brain can be observed for each frequency band.  

Given the results of the QEEG, a neurofeedback protocol is established by Dr. Preston. Neurofeedback training is a brainwave biofeedback. The process consists of placing electrodes on the scalp over the desired cortical regions and references and grounds behind the ears. The brainwave activity is read into a clinical neurofeedback unit for the frequencies and microvolts of a specific region of the brain. The clinician establishes the baseline/thresholds of slow or fast-wave activity to discourage dysfunctional waveforms and to encourage the desired functional activity. Change occurs through a process of operant conditioning which produces a gradual reconditioning and retraining in how the brain is firing and functioning. The brain receives a reward in the form of tones and changes in visual displays. The reward system creates a shift in the brain's way of firing and creates new neuronal pathways. As the shifts occur, the progress of change can be seen by the client objectively during and at the end of each session. As the objective data shifts, one starts to experience improvements in symptoms. These changes can be permanent. 


There is much literature to back the efficacy of this process 

As an example, The American Academy of Pediatrics reached the conclusion in October 2012 that EEG Biofeedback (aka Neurofeedback) is a level 1 (Best support) Evidence-Based Practice for the Attention and Hyperactivity and other recent evidence of the efficacy of the Neurofeedback for ADHD.

A creative psychologist at the University of Chicago made a very important discovery. Dr. Joe Kamiya discovered that some of his research subjects could learn to control the amplitude and frequency characteristics of their own electroencephalogram (EEG) if provided feedback about those characteristics. Many psychologists and medical practitioners soon sensed the possibilities such operant control of the nervous system electrical activity might have for clinical treatment. Within a few years, the term biofeedback was applied to these methods and to similar procedures involving other physiological processes. One of the first successful applications of biofeedback (EEG biofeedback or neurotherapy) was in the training of the brains of children having intractable epilepsy which had not responded to medications or surgery. the first application occurred as far back as the 1950s.

Frank H Duffy, M.D., a Professor and Pediatric Neurologist at Harvard Medical School stated in an editorial in the January 2000 issue of the journal "Clinical Electroencephalography" that scholars literature now suggest that neurofeedback, "should play a major therapeutic role in many difficult areas. In my opinion, if any medication had demonstrated such a wide spectrum of efficacy it would be universally accepted and widely used: (p.v). "It is a field to be taken seriously by all" (p.vii) A large body of literature exists and is accessible on all search engines by using keywords such as: quantitative EEG, neurotherapy conditions

Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS)

Various protocols for neurotherapy exist for many illnesses. However, due to the unique brain abnormalities in CFIDS clients, those protocols have generally not been effective in attempting to relieve the symptoms of those suffering from CFIDS.

After using several of these neurotherapy protocols in initial training studies of the early 90’s, Siber Imaging developed and fine-tuned a protocol which has been successful with hundreds of clients. This protocol must be individually designed, as each client responds in a unique way. The training protocol used is specifically tailored for each client based on the length of illness, client’s EEG dysfunction, and the client’s physical and cognitive stamina.

In CFIDS clients, it is necessary to follow a very careful, slow process in increasing under-active and reducing overactive brainwaves, to avoid actually exacerbating symptoms. Since each client’s EEG and progress are unique, the initial training sessions may involve routine experimentation to establish the proper training parameters. Dr. Preston has believed since the early 90’s that many CFIDS client’s symptoms are neurally-mediated (brain regulated). These neurally-mediated symptoms include: nausea, sleeping difficulties, balance disturbances, memory deficits, concentration and attention difficulties, tremors, mood disturbances, seizure activity and dysautonomia such as heart irregularities, esophageal spasms and hypotension.

Many CFIDS clients have compared their cognitive difficulties to being “in a fog”. In many ways, the CFIDS brain is functioning as though it is asleep, even though the client is awake. Careful evaluation of data taken from hundreds of CFIDS clients showed abnormal increases in slow wave and fast wave activity compared to healthy controls and clients with other diseases.

Essentially CFIDS clients are utilizing non-functional wave-forms such as Delta, Theta, and Gamma to perform functional tasks in a compensatory way. This slow wave activity is consistent with a metabolic encephalopathy (brain injury). Research has shown that the brain activity of the CFIDS client speeds up when the eyes are closed and it slows down when the eyes are open, which is the opposite of a normal response. This may be one reason that conventional EEG results for CFIDS clients are often evaluated as “normal”, since they are typically done in an eyes-closed position. CFIDS clients display unique functional brain abnormalities only when you compare the data of clients/controls while being cognitively challenged with the eyes open.
