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.” A cap is placed on the client’s scalp and electrodes record the brainwave activity. Brain waves occur at various frequencies and are grouped in bands or ranges referred to as Delta, Theta, Alpha and Beta. Normally, Delta waves are associated with sleep, Theta waves with drowsiness and creativity, Alpha with relaxed alertness and Beta with concentration, memory, speech and other cognitive tasks.
qEEG is used by Siber Imaging
to evaluate clients. Conventional hospital EEGs, are normally done with the client in a resting, eyes-closed and sleep-deprived condition. In contrast,Siber Imaging
conducts qEEG’s with clients in both eyes-closed and eyes-open conditions and performing mental tasks (reading, repeating back information, answering questions) during the recording of data.
qEEG helps clarify brain dysfunction, document cognitive decline, and track training efficacy. Perhaps most importantly, the qEEG is an important tool for developing a client-specific neurotherapy protocol (brain rehabilitation program) that can help reduce the frequency and severity of symptoms.
Our practice utilizes industry standard QEEG technology, agreed upon by the founders of this field that a QEEG is necessary for a successful neurotherapy experience.
New state of the art equipment brain master technology: Discovery24
The Discovery 24E is a 24-channel EEG and DC amplifier that is an evolution of the technology used in the 2E and 2EA (Atlantis) series of EEG biofeedback devices. It is currently available for field testing. It is fully compatible with QEEG systems such as NeuroGuide , Loreta, SKIL , and WinEEG, and incorporates BrainMaster training capabilities including amplitude and connectivity training, including Live Z-Score training.

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. In neurotherapy, the goal is to bring order to a disordered brain physiology through operant conditioning, and should be thought of as a technique of rehabilitation. The closest model for comparison is the physical therapist using various modalities to rehabilitate an injured or paralyzed muscle in order to restore function. Many conditions, including chronic fatigue syndrome, ADD/ADHD, depression, stroke, epilepsy, closed head injury and others give rise to chronic under-arousal and/or over-arousal of various areas of the brain. In these conditions, lower frequency brain waves associated with sleep, drowsiness and relaxed alertness are overactive when they should not be. Likewise, higher frequency waves associated with concentration, memory, speech and other cognitive tasks are underactive. This relative overabundance and lack of appropriate brainwaves, depending on the particular locations of the brain affected and the frequencies involved, results in a wide range of symptoms: profound fatigue, problems sleeping, headaches, memory problems, emotional disturbances, difficulty concentrating, hyperactivity, speech and reading problems, motor and balance problems and many others. The common link to all these seemingly disparate symptoms lies in the brain’s role as the central actor in controlling and directing so many of the body’s activities and processes. Across the past several decades, both research and clinical experience has shown neurotherapy to be an effective training for conditions where the underlying cause of the symptoms results from dysfunction in the brain. Neurotherapy helps to inhibit the production of underactive or overactive waveforms and restores the brain to normal or near-normal functioning.
Learn About In-Home Treatment
During a neurotherapy session, electrodes are placed on the client’s scalp to monitor brainwave activity in one or two specific locations. The signal from these leads is displayed on a computer screen. The client sits still and relaxed, attention focused calmly on the screen. Based on a set of training parameters, the computer evaluates the client’s brainwaves. Whenever there is increased activity of the desired brainwaves and reduced activity of the undesired brainwaves, the client receives a visual and auditory “reward.” Through a process known as operant conditioning, the brain begins to “learn” which levels of brainwave activity result in rewards, and seeks out increased rewards on its own, rather than as a direct result of active effort or control by the client.
Over time, both within a training session and from one training session to the next, the training parameters are gradually changed to move the brain further and further in the direction of the desired normal state of functioning. Very gradually, small, cumulative and permanent improvements occur, resulting for most clients in a significant reduction, and in some cases elimination, of symptoms. Training sessions typically last for one hour. Depending on the condition from which a client is suffering, training can take anywhere from 20 to 80 sessions.
The sessions are carried out two to three times per week to see maximal permanent improvement.
