Developments in Direct Recordings from Epileptogenic Regions in the Surgical Treatment of Partial Epilepsies

摘要: Publisher Summary This chapter discusses developments in direct recordings from epileptogenic regions the surgical treatment of partial epilepsies. The two factors that permit identification seizure foci are recording deep cortical brain difficult access and continuous monitoring by radiotelemetry with ample time under favorable conditions to examine interictal, preictal, ictal periods. electroencephalogram (EEG) signal is characteristic activity its wave-form propagation pattern when it occurs several regions. Ultimately, leads repetitive, high-amplitude spike discharges. method has disadvantages interposes a diagnostic operation into patient's introduces possibilities infection or bleeding. preliminary results EEG surveying possible zones means indwelling electrodes useful instances epilepsy drug-resistant.
