摘要： A method which is accurate and yet relatively simple, rapid and inexpensive for estimating 3-D coordinates of EEG (electroencephalograph) electrode positions on the head. The electrode positions of any number of scalp electrodes placed according to the standard 10/10 electrode position system are computed by a computer system based on 14 manually measured inter-electrode distances and 9 electrode-to-skull landmark straight-line distances. The measurements are made manually using digital calipers.

摘要： A testing method and system for testing the mental performance capability of a human subject includes a digital computer workstation which presents a test to the subject, such as visumotor memory task. Simultaneously, a physiological sensing and amplification device amplifies and analyzes the subject's brain waves, eye activity, scalp and facial muscle activity, heart activity, respiration and/or skin conductance. The subject's test scores and physiological activity are compared, by the workstation, with previously collected normative measurements for that subject to determine if the test was passed with a passing score and, if so, whether the subject, in order to pass the test, exceeded a standard based upon the subject's normal mental effort in taking the same or similar tests.

摘要： An improved brain wave electroencephalograph (EEG) method measures the physical positions of EEG electrodes applied to the subject's scalp. A set of standard cross-directional lines are obtained to provide measurements of the subject's head and a computer system automatically defines the subject's head shape according to predetermined head shape classes. The position of the electrode on the subject's scalp is then determined by scaling the measurements of the subject's head to a head model of the same head shape class.

摘要： A magnetoencaphalogram (MEG) detects the neuromagnetic brain signals of a subject by bringing a set of magnetic sensors, preferably SQUIDs (superconducting quantum interference device), close to the scalp of the subject. The adverse effect of environmental magnetic noise is reduced by using a second set of magnetic sensors which are placed near the subject. The system includes a bandpass filter, to divide the signals from the various sensors into predetermined frequency bands, and a computer to provide a least squares noise component estimate of the noise from each brain wave sensor and to calculate therefrom a filtered brain wave signal having reduced noise.

摘要： A dry electrode, which is a single-plate capacitor, is particularly adapted to be placed on a patient's scalp to detect brain waves in an EEG system. The electrode comprises a metal disk sandwiched between very thin and relatively thicker layers of ceramic. The metal disk is attached to a small disk printed circuit board that carries an amplifier to amplify the brain waves detected by the electrode. The quality of contact of the electrode with the patient is measured by applying a pulse or voltage step through the ground electrode.

摘要： In an EEG (electroencephalogram) system to detect brain waves from a subject, the adverse effect on the EEG recording of artifact due to head, body and eye movements is reduced. A head and body movement reference signal can be provided by an accelerometer, motion detector or, alternatively, spatial average of EEG channels. Eye motion sensors are used as a reference for eye movement artifacts. A composite reference signal consists of the head, body and eye movement reference signals. The contaminated EEG is the primary input to the adaptive movement and eye artifact canceler, in which an adaptive filter estimates the contaminants in the measured EEG data, and then subtracts them from the primary signal to obtain the corrected EEG data.
