Z-Score Training at TetraNeuroNet


 

The NeuroField technology incorporates low intensity, pulsed electromagnetic  stimulation, heart rate variability (HRV) and electroencephalography (EEG) all in one biofeedback system.

Surface Z-score training- By interfacing with a normative database, a person's brain activity is measured in terms of power and connectivity and compared to their age and gender matches in real time z-scores. Using the same reward based operant conditioning model as neurofeedback, the feedback is based on the criteria set by the clinician. The criteria is set differently with z-score training and is concerned with what percentage of the total metrics trained a person is able to bring into a normative range. The theory is that the brain is then being given more of a choice as to what to train. Z-score training can take place with 2, 4 or up to 19 channels of EEG.

The z-scores that are outside of 1.98 z-scores above or below the norm are what I look at first. I look at the location where the aberrant EEG activity is occurring. If the function associated with location of the activity is correlated to the symptoms the client is seeking to change, I think about z-score training in this area. 


Z-SCORE
training can be done in a variety of ways.

•With the Neurofield system, z-scores can be used to drive the stimulation. Z-scores are measured at the sites to be trained.  If the stimulation given drives the EEG activity into a normative range, an auditory reward is given.

•With surface EEG, rewards (music, images, movie, playing games) based on operant conditioning are activated when the EEG activity comes into a normative range.

•With LORETA 3D imaging, targeting subcortical drivers and networks. Great amounts of research has gone into protocol creation based on symptom check lists, functional networks of Brodman areas and neuropsychological focuses such as apraxia. (see LORETA z-score page for more details)
