EEG after sleep deprivationepilepsy diagnosisMEGValidationMEG and EEG after sleep deprivation (EEG-SD) are applied as diagnostic tools in the evaluation of patients with possible epilepsy. There is no gold standard to check whether the diagnosis based on these two modalities is correct. The best ...
Thesource S1 is related to epilepsy and S2 is irrelevant to epilepsy图7. 三种算法对癫痫EEG的源重建。a) 平均尖波信号的拓扑图。尖波的最大值记录在FC1位置。b) 在振幅峰值(蓝色虚线)处的源成像结果被叠加在术前脑MRI图像上。算法定位了两个源,并重建了它们的时间过程。源S1与癫痫相关,S2与癫痫无关...

OPM-MEG脑磁图仪可用于测量一些通常由MEG和EEG报告的电生理事件。通常,对许多模式的感觉刺激的诱发反应进行评估,OPM可以提供高保真的测量(Borna A.et al. Non-invasive functional-brain-imaging with an OPM-based magnetoencephalography system. PLoS One. 2020; 15e0227684) 同样,在许多频段上都能检测到脑震荡,...
b) The source imaging results at the peak of amplitude(the blue dash line) are imposed on pre-surgical brain MRI images. Thealgorithms localize two sources and reconstructs their time courses. Thesource S1 is related to epilepsy and S2 is irrelevant to epilepsy图7. 三种算法对癫痫EEG的源重建...
The EEG and MEG are very close methodologies, since the main sources of both kinds of signals are essentially the same, i.e., ionic currents generated by biochemical processes at the cellular level. Traditionally, EEG/MEG signals are described in terms of frequency bands, the limits of which...
In MEG and EEG studies, the accuracy of the head digitization impacts the co-registration between functional and structural data. The co-registration is one of the major factors that affect the spatial accuracy in MEG/EEG source imaging. Precisely digitized head-surface (scalp) points do not onl...

The model parameters were tuned in in order to reproduce the patient-specific seizure propagation patterns as recorded with invasive EEG. We defined a personalized search algorithm that combined structural ...
Naik and *Mamta Karnik *Epiclinic, Epilepsy Center for Children, Specialty Childcare, Mumbai, India . Purpose: To study EEG abnormalities in children with a first unprovoked seizure. Methods: In a prospective cohort study, EEG findings were studied from 63 children with a first unprovoked a...
