  • METHOD AND APPARATUS FOR PROCESSING ELECTROENCEPHALOGRAM (EEG) SIGNALS
    Publication number: 20170311870
    Abstract: A method of processing EEC signals received from a plurality electrodes. The method comprises processing the EEC signals to determine a modulation index value for each electrode, determining one or more electrodes that have a modulation index value above a threshold level observed during ictal activity, and using the determined one or more electrodes, to identify one or more possible regions of interest corresponding to seizure zones of a subject's brain.

  • SYSTEM AND METHOD FOR COGNITIVE RHYTHM GENERATION
    Publication number: 20160287871
    Abstract: A method of modeling time-dependent electrical activity of a biological system, the method comprises transforming an input through at least one dynamic mode to yield at least one modal output; processing the at least one modal output to yield at least one amplitude variable and at least one phase variable; and mapping the at least one amplitude variable and the at least one phase variable to an observable output.

  • METHOD AND APPARATUS FOR PROCESSING EEG SIGNALS
    Publication number: 20160287162
    Abstract: A method of processing EEG signals obtained from a subject using a grid of electrodes comprises processing the EEG signals to determine a phase coherence measure of the EEG signals for selected electrode pairs of said grid; determining electrode pairs where strong phase coherence of the EEG signals is observed in a low frequency range during interictal activity; and using the determined electrode pairs to identify a possible seizure zone of the subject's brain.
