Clinical application of dipole models in the localization of epileptiform activity.

摘要: Summary: Routine clinical interpretation of EEG using visual inspection traces is a time-honored, but simplistic, form analysis. This particularly true in attempts to localize an epileptogenic focus by means spike or seizure waveforms. Improved understanding the cortical substrates these potentials has allowed us identify their likely cerebral origins through spatio-temporal analysis scalp voltage fields. Equivalent dipole modeling one such technique. Although imperfect representation sources, proper models can lead far better characterization localization and propagation. Modern techniques 3-D MRI reconstruction realistic head have both improved accuracy provided displaying results image individual’s brain.
