  • Computatonal tool for pre-surgical evaluation of patients with medically refractory epilepsy
    Patent number: 9277873
    Abstract: A method of identifying an epileptogenic zone of a subject's brain includes receiving a plurality of electrical signals from a corresponding plurality of surgically implanted electrodes, calculating a first plurality of connectivities between each pair of electrodes based on a portion of each of the plurality of electrical signals corresponding to a first time period, assigning a rank corresponding to each electrode for the first period of time based on the first plurality of connectivities to provide a first plurality of ranks, calculating a second plurality of connectivities between each pair of electrodes based on a portion of each of the plurality of electrical signals corresponding to a second time period, assigning a rank corresponding to each electrode for the second period of time based on the second plurality of connectivities to provide a second plurality of ranks, identifying a cluster of electrodes among the plurality of electrodes based on relative changes between the first plurality of ranks fro
