摘要： The invention provides methods and apparatuses for monitoring task engagement by measuring beta frequency oscillations in the brain. Changes in power, frequency, and/or coherency of beta frequency oscillations correlate to an individual's engagement in or disengagement from a task. Accordingly, beta frequency oscillations can be used to determine if an individual prematurely disengages from a task, to diagnose if a person has a disorder affecting task engagement, and to evaluate the efficacy of a treatment for a disorder.

摘要： Disclosed is a biopotential analysis system and method of the present invention for determining, in a noninvasive manner, cerebral electrical properties. A suitable electrode and amplifier system is used to obtain biopotentials from the region of interest. Surface electroencephalographic signals are then digitized and transmitted over a serial RS232C line to a host computer where a two minute long signal is divided into 30 consecutive four second intervals. A fast Fourier transform (FFT) is then performed on every interval, and the resulting fast Fourier transforms are then used to produce bispectral complex triple product and bispectral real triple product arrays for that interval. The complex triple product arrays of all intervals are added together, and the real triple product arrays of all intervals are also added together. Each element in the final complex array and final real array is then divided by 30 (the number of intervals) to produce an average complex triple product array and an average real triple product array. The magnitude squared of each element in the complex triple product array is divided by the corresponding element in the real triple product array to form the bicoherence array. The bicoherence array is displayed on a video terminal or plotted, and is used as a figure of merit for the assessment of cerebral electrical function.

摘要： A method and system for the quantitative description of human abnormal brain states, for example, to distinguish cerebral death from a barbiturate induced deep coma, includes an electroencephalograph (EEG) system utilizing scalp electrodes and amplifiers. A computer based system controls a multimodal stimulator (clicks, flashes, etc.) to provide evoked response data for different sensory systems. The ongoing EEG and averaged response data are processed quantitatively and compared with previously stored normative data, describing brain states in patients free of head trauma, to calculate a set of Z-transformations. The Z-transformations define Z, the brain state vector (BSV), which may be visually displayed. The length, direction and change of BSV over time provide an evaluation of the anatomical location of any damage, the severity of functional impairment and the rate of improvement or deterioration of the patient's state in order to aid in selection and guidance of treatment.
