Abstract: A method of whole-brain EEG neurofeedback training of a trainee using live Z-scores from 4 channels of EEG signals to acquire 248 Z-scores from 6 simultaneous interconnectivity paths. The feedback system is endowed with the ability to establish training targets and to use derived metrics to produce feedback of an auditory, visual, vibrotactile, or other sensory or direct nature. The feedback signals are determined by a multivariate analysis that takes into consideration how measured variables compare with predefined criteria, thus producing a statistical correlation in real-time, in conjunction with a reference or normative database, rule-set, algorithm, discriminate function, or classification system.

Abstract: This invention is a validation process for ipsative assessments. Respondents are connected to an Electroencephalograph (EEG) and some or all of the ipsative assessment questions are asked again while connected to the EEG. The EEG measuring frontal lobe responses in terms of gamma waves is compared with the assessment questions. Positive responses provide one frontal lobe response in terms of gamma waves, negative or false answers provide a different gamma response and neutral questions provide a neutral gamma response. Reading the responses then tells whether the respondent initially responded with integrity, if so the assessment is validated.

Abstract: An EEG neurofeedback and total evoked brain activity measurement methods utilize minimum ambient EEG activity as stimulant frequencies. A method of using repetitive stimulation in conjunction with EEG neurofeedback protocols is described. Electrodes, attached to a subject's scalp, transmit electroencephalographic (EEG) signals from the subject. These signals are in response to the visual and/or auditory stimuli being displayed to the subject. The resultant EEG signals are then filtered at pre-defined frequencies or frequency bands. The output from the filtered EEG signals is then analyzed and monitored for short-term state changes. The invention also uses flicker stimulation, real-time signal filtration and feedback, feedback during audio and visual stimulation derived from filtered outputs, and fundamental and integral harmonics in combination with total evoked response.

Abstract: A biofeedback training system and method which utilizes biological signals from a trainee to influence actions and events in an activity or game displayed to the trainee. A level of intelligence in a displayed activity or game is used a biofeedback variable. Decision-making rules or other abilities within an embedded game player are introduced and controlled as additional types of biofeedback variable, and represent awards in a training process. The methods and systems can be applied to any activity or game that includes goal-seeking behavior and that can be configured for automatic play by goal-oriented rules. The action and content of game-like biofeedback displays may be influenced or dictated by biological signals from a trainee viewing the display.

The system utilizes distributed processing that includes localized processing capability allowing a user to initiate a self-controlled biofeedback session and additionally includes remote processing capabilities enabling simultaneous remote analysis and monitoring of the session.

Abstract: A method of reducing undesirable brain wave pattern using selective photic stimulation. Electrodes, attached to a subject's scalp, transmit electroencephalographic (EEG) signals from the subject. These signals are in response to the photic stimulation being displayed to the subject. The resultant EEG signals are then filtered, while control logic monitors a predetermined EEG frequency band and feeds back the filtered EEG signal to the subject via the photic stimulation. The photic stimulator is then turned on and off rapidly, in response to the amount of energy in a predetermined band of the subject's EEG, with the intent of reducing an undesirable brain rhythm.

Abstract: An EEG electrode system for establishing positive electrical contact with the scalp, uses absorptive electrode wrap material in contact with metallic electrodes, with saturated electrode wrap material placed in contact with the scalp. Saturation of the electrode warp material with a conductive solution such as saline provides mechanically and electrically stable contact at multiple scalp electrode sites. An electrode wrap holder assembly holds the electrode wrap and an exposed portion of the electrode wrap in contact with the scalp, while providing access to the electrode wrap for re-wetting with the conductive solution if required. The electrode wrap holders are mounted in straps, hard caps or other headgear. Adjustment of the electrode wrap holders within the mounts further compresses the flexible, absorptive electrode wrap, causing flow of the conductive solution therein and enhancement of the electrical contact.
