Source Connectivity Analysis from MEG and its Application to Epilepsy Source Localization
Brain Topography - - 2012
Dipole tracing in childhood epilepsy with special reference to Rolandic epilepsy
Brain Topography - Tập 4 - Trang 193-199 - 1992
To assess the clinical applicability of dipole tracing in childhood epilepsy, the location and stability of electric source generator of focal spikes seen in EEG of epileptic children were investigated using this method. The patients were divided into 3 groups; benign childhood epilepsy with centrotemporal spikes (BCECS, Group A, n=14), other types of epilepsy with centrotemporal spikes (Group B, ......
Topographic mapping and source localization of the pattern onset visual evoked magnetic response

Brain mapping: A contribution to linear interpolation
Brain Topography - Tập 5 - Trang 283-288 - 1993
Topographic mapping of brain electrical activity has become a powerful tool in neurological diagnosis. Maps are obtained from a reduced number of actual measurements by means of mathematical interpolation. Most of these systems use linear combination of the values measured and, in spite of its importance, the choice of the exponent "n" in the weighting function is made ad hoc. In this paper we pre......
Microstate Analysis Reflects Maturation of the Preterm Brain
Brain Topography - - Trang 1-14 - 2023
Preterm neonates are at risk of long-term neurodevelopmental impairments due to disruption of natural brain development. Electroencephalography (EEG) analysis can provide insights into brain development of preterm neonates. This study aims to explore the use of microstate (MS) analysis to evaluate global brain dynamics changes during maturation in preterm neonates with normal neurodevelopmental ou......
A correlation study of averaged and single trial MEG signals: The average describes multiple histories each in a different set of single trials
Brain Topography - Tập 8 - Trang 385-396 - 1996
Our understanding of the link between electrical events in the brain and behaviour is based on indirect measures. Positron Emission Tomography (PET) and functional Magnetic Resonance Imaging (fMRI) rely on haemodynamic processes which are slower by two to three orders of magnitude than the processes characterizing normal and pathological brain function. Direct invasive measurements of the electric......
Source model and scalp topography of pattern reversal visual evoked potentials to altitudinal stimuli suggest that infoldings of calcarine fissure are not part of VEP generators
Brain Topography - - 1995
Visual evoked potentials (VEPs) to pattern reversal vertical bar stimuli were recorded from 19 scalp, 2 zygomatic and 3 inion derivations referenced to digitally linked earlobes in 50 controls. 1, 2 and 4 cycles per degree (cpd) patterns were presented as full field (FF) stimuli, on upper and lower hemifields (UHF-LHF), upper and lower quadrants and with the occlusion of central and peripheral UHF......

Spatial Enhancement of Event-Related Potentials Using Multiresolution Analysis
Brain Topography - - 1998
Multiresolution analysis is a potentially useful tool to enhance the brain's electrical fields (spatial distributions of event-related potentials (ERP)), and to bring out spatial features which may not be seen in the fields before enhancement. For comparing different images (slices from ERP of different subjects or from the same subject but evoked by different stimuli), we define a measure (surfac......
