Neurofeedback Modality


LORETA Z-Score Training, Z-Score Neurofeedback, pEMF, and LENS

The Neurofeedback Center offers these different neurotheraphy modalities and what is selected for your treatment will be determined from a complete evaluation.

LORETA Z-Score Neurofeedback Training ?

LORETA refers to low resolution electromagnetic tomography. This is a kind of QEEG analysis that provides an estimation of the location of the underlying brain generators (e.g., the anterior cingulate, insula, fusiform gyrus) of the patient’s EEG activity within a frequency band. It does require as with 19 channel z score training a more labor-intensive preparation where an entire electrode cap with
19 electrodes must be applied in every session. However this approach is a great breakthrough for many to potentially improve outcomes in difficult cases and or shorten the length of treatment.

What is Live Z Score Training?

Live z score training combines training the frequencies with a scientifically normative database. This allows the feedback to guide the patient toward normalized function moment to moment for their age and gender. Continuous calculations are being computed comparing the way that the brain is functioning on different variables. When 19 channels are used it is literally training the entire brain and all the connectivity issues between each site, (6,700 parameters at one time), which is quite amazing. Feedback is given in the form of sound, games and or a DVD. When the brainwaves are moving toward the normalized direction they get more feedback in the form of changes on the screen or in the musical sounds. This form of training has helped significantly decrease the number of sessions required to help change their symptoms from the traditional type of neurofeedback where only one or two electrodes are used.

What is Pulsed Electromagnetic Frequency (pEMF)?

This technology incorporates very low intensity, pulsed electromagnetic field (pEMF) stimulation, and electroencephalography (EEG) all in one biofeedback system. It can generate pEMF frequencies from 0.31-300,000 Hz. The pEMF output ranges from 1-40 microtesla, but the low intensity pEMF is 10,000,000 times weaker than traditional rTMS (transcranial magnetic stimulation) which was approved by the FDA in 2008 for the treatment of depression.
A 19 channel EEG amplifier can used with the pEMF device to measure EEG in between pEMF stimulation utilizing the real time z-score procedure and has been integrated in the normed database for use with 19 channel LORETA and Surface neurofeedback z-score platform. This technology is quite remarkable.

What is Low Energy Neurofeedback?

The Low Energy Neurofeedback System (LENS) is an EEG biofeedback system used in clinical application and research in the treatment of central nervous system functioning. It is unique in the field of Neurofeedack in that instead of only displaying information on a computer screen to assist the patient in conditioning healthier brainwave patterns, the LENS uses weak electromagnetic signals as a carrier wave for feedback to assist in reorganizing brain physiology.

This Neurofeedback consists of feeding-back to the patient, through extremely low energy fields, a gentle EEG-driven signal based on the dominant brainwave rhythm. The signal is transmitted as a radio wave and cannot be felt, although patients generally report feeling different after the session. No special effort is required of the recipient; merely to sit quietly and allow whatever experiences emerge. Jagged, low frequency, high amplitude, brainwaves that cause the diagnostic problems soften and diminish with each training session. Most clients acquire a greater sense of clarity, self-control, and balance.

How Long Does Neurofeedback Take for Results?

It always depends on the nature of the dysregulation. For problems of recent origin, in a fairly healthy nervous system, Neurotherapy may be short (10-20 sessions). For problems of longer duration, a longer course of Neurotherapy (20-40 sessions). For deeply entrenched problems that are similar to ones your parents or even grandparents had: still longer, commensurate with the amount of time the condition has existed. Serious disorders such as Cerebral Palsy, Stroke, Epilepsy, and TBI may require many treatments, but over time, there is usually a steady gradient of improvement, rather than decline.
