Computational modelling in source space from scalp EEG to inform presurgical evaluation of epilepsy

Publication date: Available online 22 November 2019Source: Clinical NeurophysiologyAuthor(s): Marinho A. Lopes, Leandro Junges, Luke Tait, John R. Terry, Eugenio Abela, Mark P. Richardson, Marc GoodfellowAbstractObjectiveThe effectiveness of intracranial electroencephalography (iEEG) to inform epilepsy surgery depends on where iEEG electrodes are implanted. This decision is informed by noninvasive recording modalities such as scalp EEG. Herein we propose a framework to interrogate scalp EEG and determine...

Influence of reference electrode position on the compound muscle action potential

Publication date: Available online 22 November 2019Source: Clinical NeurophysiologyAuthor(s): Sanjeev D. Nandedkar, Paul E. BarkhausAbstractObjectiveWhen the compound muscle action potential (CMAP) is recorded in motor nerve conduction studies, the reference (E2) electrode can make a significant contribution to the CMAP. This study investigates the E2 recorded signal and its effect on CMAP measurements when E2 electrode is placed at different sites.MethodsThe CMAP was recorded using the active electrode...

Deriving pediatric nerve conduction normal values in the very young (<3 years)

Publication date: Available online 22 November 2019Source: Clinical NeurophysiologyAuthor(s): Joe F. Jabre, Matthew C. Pitt, Ralph SmithAbstractObjectiveThis work describes our efforts to obtain nerve conduction studies normal values in a pediatric cohort between birth and 3 years of age using the extrapolated norms or e-norms method. Interpretation of these studies poses major challenges when no reliable normal values can be found in the literature.MethodsThe e-norms method was used to derive a...

A skew-based method for identifying intracranial EEG channels with epileptic activity without detecting spikes, ripples, or fast ripples

Publication date: Available online 22 November 2019Source: Clinical NeurophysiologyAuthor(s): Anne H. Mooij, Birgit Frauscher, Jean Gotman, Geertjan J.M. HuiskampAbstractObjectiveTo develop a method for identifying intracranial EEG (iEEG) channels with epileptic activity without the need to detect spikes, ripples, or fast ripples.MethodsWe compared the skew of the distribution of power values from five minutes non-rapid eye movement stage N3 sleep for the 5-80 Hz, 80-250 Hz (ripple), and 250-500...
