Live Z-Score Training

BrainMaster Technologies, Inc. is unique in providing live LZT methods that provides Multivariate Proportional™ (MVP) variables for use in training. MVP variables are continuous, proportional values that are used in training in the same ways that conventional values such as absolute power, relative power, or raw coherence values have been used in the past. The key to this innovation is that the new MVP variables provide complex yet intuitively simple measurements that are field-proven in producing client results that are rapid, concise, and lasting.


Other approaches to using live Z-Scores typically produce only an “on/off” response, depending on whether one or more Z-Scores are within a range. Thus, the brain is provided with information that tells it whether or not it meets a condition but does not provide any proportional or “how much” information to the trainee. This limits the brain’s ability to learn and respond to the important EEG parameters. Also, such methods do not lend themselves to tuning the training beyond setting the target sizes. BrainMaster’s MVP methods produce new quantitative variables that are not simply “yes/no”, but provide real-time, proportional feedback that can be used for sounds, videos, games, or other feedback methods that respond to either “on/off,” “how much,” or a combination of such control variables. This provides a level of guidance that reduces the number and length of sessions necessary to see results.


Another key element of BrainMaster’s approach is the ability to dynamically change the difficulty of the training on multiple levels, in real-time without interrupting training. This is analogous to being able to adjust the throttle, choke, etc. of a vehicle while it is in motion, which is an essential element of clinical application. With the PZOK method, clinicians commonly adjust the size of the training window and also the percentage of Z-Scores which are required to be met, in order to obtain an reward. This was a non-obvious, yet critical step in the evolution of BrainMaster’s exclusive LZT technology.


qEEGPro Live Z-Score Training DLL


qEEG_Pro_imageThe qEEGPro Live Z-Score DLL provides a new standard in realtime qEEG-based neurofeedback. Among its innovative capabilities is the ability to define Z-Score target ranges individually for each client, so that you are not limited to predefined bands. All qEEGPro DLL frequency parameters are computed on 1-Hz boundaries, (1-50Hz) so that any desired range can be visualized, imaged, or trained.


The DLL supports surface Z-Scores and maps, as well as sLORETA.



Applied Neuroscience BrainMaster Z-Score DLL


533-404A scientifically and medically designed software approach which will analyze selected training sites; compare those sites with the NeuroGuide normative database, and automatically train those sites using a designated targeting protocol. Protocols are automatically personalized to the client’s individual needs. Significantly reduces guesswork, particularly during brain connectivity training. Most effective when preceded by a full QEEG assessment. Training consists of the following estimators: absolute power, relative power, power ratios, asymmetry, coherence, and phase. Advanced built-in functions and variable definitions facilitate simple design of complex targeting strategies with intuitive trainee feedback. Any combination of targeted Z-Scores may be included in the protocol design, which may train toward normative values, or can be biased for peak- performance, self-awareness, mental fitness, healing, or other neurofeedback applications.

Z-Plus Z-Score Add-On Training


533-418-19This package is optional, and extends the existing LZT training software with new, innovative metrics and displays. These further empower the clinician and the client to identify and train relevant EEG parameters and their changes. Z-Plus is available for Atlantis or Discovery, and is built into the BrainMaster series of software.


Starting with the “Percent ZOK” training method, BrainMaster has developed a family of training variables that intuitively incorporate any or all of the Z-Scores, and turn them into a single proportional variable. With these variables, any combination of channels, parameters (absolute power, relative power, power ratios, coherence, phase, asymmetry ), or frequency components (delta, theta, etc.) can be trained. Regardless of the number of channels or parameters chosen, this variable always has the same meaning. It is the “percent of Z-Scores that are within the target limits.” It has a maximum value of 100 (100% normal), that continuously varies in time, and is useful both for training and for assessing the overall condition of the client.


Z-Motive is based upon new algorithm that computes a comprehensive system metric that is based upon the positions, weights, and trajectories of multiple Z-Scores, so as to provide a measure of not only the state of the brain, but also its tendency for change. Any or all Z-Scores can be included in the Z-Motive calculation, which provides an instantaneous comprehensive indication of brain state and brain change, when used for neurofeedback training.


Z-Motive combines the concepts of self-regulation, dynamic training, and adaptive targeting. Unlike methods that require the clinician to predefine precisely which Z-Scores to train and within which ranges, Z-Optimal presents the brain with a comprehensive metric that reflects all EEG parameters in a single, proportional value. This value provides a consistent target that reflects all training parameters on a continuous basis, and does not depend on particular targets being “hit” or “missed.” Rather, all targets contribute to the total state so that the brain receives global information.



BrainAvatar Analysis


Analysis is a powerful new functin that brings basic qEEG functions into the BrainAvatar® software. With this option, it is possible to select segments of EEG and perform a statistical analysis that provides Z-Score, text summaries, surface maps, sLORETA 3-D images, and Excel spreadsheets containing summary data. Analysis provides summary values for power and connectivity metrics expressed as Z-Scores, providing a fast and useful mini-assessment. while this is not a replacement for a full qEEG report and it does not include discriminants or other advanced functions, it is an excellent way to get a basic set of summary maps and values based on normative comparisons, without haveing to use additional software or services.
