Comparison of high resolution EEG methods having different theoretical bases
Brain Topography - Tập 5 - Trang 361-364 - 1993
P. L. Nunez, R. B. Silberstein, P. J. Cadusch, R. Wijesinghe
Mathematically simulated data is used to obtain direct comparisons of the accuracies of spline/Laplacian and cortical imaging algorithms in predicting cortical potential. Even though the two approaches have quite different theoretical bases, the two methods provide nearly identical estimates of cortical activity at scales greater than about 2 or 3 cm when 64 electrodes are used.
Mapping the Semantic Homunculus: A Functional and Behavioural Analysis of Overt Semantic Generation
Brain Topography - Tập 21 - Trang 22-35 - 2008
Carrie Esopenko, Ron Borowsky, Jacqueline Cummine, Gordon Sarty
Previous neuroanatomical research has shown that semantic processing of action-related language activates the premotor, motor, and sensory cortices somatotopically (e.g., Tettamanti et al., J Cognitive Neurosci. 2005;17(2): 273–281, using a listening task, and Hauk et al., Neuron. 2004;41:301–307 and Pulvermuller et al., Eur J Neurosci 2005;21:793–797; J Cognitive Neurosci 2005;17(6):884–892 using...... hiện toàn bộ
Source Connectivity Analysis from MEG and its Application to Epilepsy Source Localization

Dipole tracing in childhood epilepsy with special reference to Rolandic epilepsy
Brain Topography - Tập 4 - Trang 193-199 - 1992
Harumi Yoshinaga, Rumi Amano, Eiji Oka, Shunsuke Ohtahara
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, ...... hiện toàn bộ

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
Daniel C. Casaglia, Guillermo G. Pantaleo
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...... hiện toàn bộ
Unified Retrospective EEG Motion Educated Artefact Suppression for EEG-fMRI to Suppress Magnetic Field Gradient Artefacts During Motion
Brain Topography - Tập 34 - Trang 745-761 - 2021
Danilo Maziero, Victor A. Stenger, David W. Carmichael
The data quality of simultaneously acquired electroencephalography and functional magnetic resonance imaging (EEG-fMRI) can be strongly affected by motion. Recent work has shown that the quality of fMRI data can be improved by using a Moiré-Phase-Tracker (MPT)-camera system for prospective motion correction. The use of the head position acquired by the MPT-camera-system has also been shown to corr...... hiện toàn bộ
Microstate Analysis Reflects Maturation of the Preterm Brain
Brain Topography - - Trang 1-14 - 2023
Tim Hermans, Mohammad Khazaei, Khadijeh Raeisi, Pierpaolo Croce, Gabriella Tamburro, Anneleen Dereymaeker, Maarten De Vos, Filippo Zappasodi, Silvia Comani
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...... hiện toàn bộ
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
Lichan Liu, Andreas A. Ioannides
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...... hiện toàn bộ
