NO LONGER DO WE HAVE TO GUESS WHATS GOING ON IN THE BRAIN. WE CAN SEE IT HAPPEN LIVE, IN REAL TIME.
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.
