System for self-administration of electroencephalographic (EEG) neurofeedback training
First Claim
1. A system for self-administration of electronencephalographic (EEG) neurofeedback training through observation and control of displayed graphic images which correspond in real time to EEG signals obtained from a user of the system, the system comprising:
- an EEG module having an EEG signal amplifier connected to EEG electrodes attachable to a head of a user of the system, an electrode test, auxiliary channels, an analog-to-digital converter with 8-bit digital input and output ports, rechargeable batteries and an optically isolated port for connection to a computer, the computer having an internal interrupt timer for initiating a processing cycle between the EEG module and the computer whereby acquisition and transmission of EEG data by the module is coordinated with receipt, processing and display of EEG data by the computer, and whereby coordinated processing of user feedback is enabled by transmission of user-input control information from the computer to the EEG module,system software for generating user-control functions and graphic images which correspond in real time to EEG signals received by the EEG module and processed by the computer, anda display connected to the computer for displaying graphic images generated by the system software, wherein the graphic images include a plurality of vertically oriented thermometer bars corresponding to predetermined frequency ranges of EEG signals monitored by the EEG module, and wherein the graphic images further comprise representations of facial expressions responsive to EEG signals monitored by the system the facial expressions including the facial elements of responsive representations of right and left eyebrows and lips, whereby a user connected to the EEG electrodes can receive EEG neurofeedback training by viewing the display.

Abstract
A system for self-administered monitoring, displaying, analyzing and recording electrical activity of the brain provides indications of brain activity and a corresponding mental state of a user. A plurality of visual, auditory and tactile feedback mechanisms are integrated with the presentation of control and notification indications, to facilitate neurofeedback training of the user, The operational interface and sequencing is provided in such a manner as to provide the ability to the user to record, manage and control brain activity for different purposes including self-improvement, treatment, peak performance and recreation.
