METHOD OF IDENTIFYING A SURGICALLY OPERABLE TARGET ZONE IN AN EPILEPTIC PATIENT'S BRAIN
The method of identifying a potentially surgically operable target zone in an epileptic patient's brain includes: providing a computerized platform modelling various zones of a primate brain and connectivity between said zones; providing a model of an epileptogenic zone and a model of the propagation of an epileptic discharge from an epileptic zone to a propagation zone; obtaining a patient's personalized computerized platform; deriving the potential target zones based on modularity analysis; evaluating the target zones' effectiveness by simulating epileptic seizures propagation in the personalized patient's computerized platform; evaluating the target zones' safety by simulating spatiotemporal brain activation patterns in a defined state condition and comparing the simulated spatiotemporal brain activation patterns obtained before removal of the target zone with the spatiotemporal brain activation patterns obtained after removal of the target zone; identifying the target zones which satisfy both effectiveness and safety evaluation criteria as potentially surgically operable target zones.

MEDIAN POWER SPECTROGRAPHIC IMAGES AND DETECTION OF SEIZURE
Systems, methods and programs for processing EEG data for display and/or automatically detecting a seizure in a patient based on one or more spectrograms created from the EEG data. EEG data from a patient may be paired into channels based on electrode locations. Spectrograms are generated from EEG data from channels, respectively. The spectrograms of different channels are grouped and a median power spectrogram (MPS) is calculated for the group. The MPS may be used to automatically determine whether the patient had a seizure by applying a machined learned model (ML) model. The ML model is trained and tested using historical EEG data from a plurality of patients. The MPS or a relationship between a plurality of MPS of different groups may be displayed on a bedside monitor in real-time for viewing by a bedside clinician.

System and Method for Modeling Negatively Correlated Brain Epilepsy Network
System and method for processing, non-concurrently collected, electroencephalogram (EEG) data and resting state functional magnetic resonance imaging (rsfMRI) data, non-invasively, to create a patient-specific three-dimensional (3D) mapping of the patient's functional brain network. The mapping can be used to more precisely identify candidates of resective neurosurgery and to help create a targeted surgical plan for those patients. The methodology automatically maps the patient's unique brain network using non-concurrent EEG and resting state functional MRI (rsfMRI). Generally, the current invention merges EEG data and rsfMRI data to map the patient's epilepsy/seizure network. Correlated sections of the brain and inversely correlated sections of the brain are identified to determine which sections of the brain work in conjunction with each other and which sections work oppositely to each other during epileptic episodes.
