Noninvasive cortical imaging of epileptiform activities from interictal spikes in pediatric patients
Improved non-invasive localization of the epileptogenic foci prior to epilepsy surgery would improve surgical outcome in patients with partial seizure disorders. A critical component for the identification of the epileptogenic brain is the analysis of electrophysiological data obtained during ictal activity from prolonged intracranial recordings. The development of a noninvasive means to identi...
متن کاملEffect of cortical cooling on interictal epileptiform activities
OBJECTIVE To determine if applying chilled solution to exposed cerebral cortex can reduce interictal epileptiform activities in patients during surgery. METHODS Electrocorticography was used to record the epileptiform activity of 12 patients (ages 18-53) undergoing cortical mapping and resection surgery. Interictal spikes were counted at baseline and compared with spikes after applying room t...
متن کاملHigh-resolution EEG: cortical potential imaging of interictal spikes.
BACKGROUND It is of clinical importance to localize pathologic brain tissue in epilepsy. Noninvasive localization of cortical areas associated with interictal epileptiform spikes may provide important information to facilitate presurgical planning for intractable epilepsy patients. METHODS A cortical potential imaging (CPI) technique was used to deconvolve the smeared scalp potentials into th...
متن کاملAn empirical investigation of motion effects in eMRI of interictal epileptiform spikes.
We recently developed a functional neuroimaging technique called encephalographic magnetic resonance imaging (eMRI). Our method acquires rapid single-shot gradient-echo echo-planar MRI (repetition time=47 ms); it attempts to measure an MR signal more directly linked to neuronal electromagnetic activity than existing methods. To increase the likelihood of detecting such an MR signal, we recorded...
متن کاملInterictal Epileptiform Discharges
EEG remains the primary technique in the diagnosis, characterization, and localization of partial seizures. This review examines the significance and character of interictal epileptiform abnormailites, periodic lateralized epileptiform discharges, and ictal patterns in patients with partial epilepsy. Interictal epileptiform discharges are common and assist in the diagnosis and localization of p...
