Scalp electric potentials (electroencephalogram; EEG) are contingent to the impressed
current density unleashed by cortical pyramidal neurons undergoing post-synaptic …

Scalp electric potentials (EEG) and extracranial magnetic fields (MEG) are due to the
primary (impressed) current density distribution that arises from neuronal post-synaptic …

Coherence and phase synchronization between time series corresponding to different
spatial locations are usually interpreted as indicators of the connectivity between locations …

The construction of a tomography of neuronal sources is limited by a lack of information. A
possible way around this problem is to change the biophysical model that underlies the …

This paper proposes and implements biophysical constraints to select a unique solution to
the bioelectromagnetic inverse problem. It first shows that the brain's electric fields and …

Among the different brain imaging techniques, electroencephalography (EEG) is classically
considered as having an excellent temporal resolution, but a poor spatial one. Here, we …

We present an overview of different methods for decomposing a multichannel spontaneous
electroencephalogram (EEG) into sets of temporal patterns and topographic distributions. All …

Functional imaging of electric brain activity requires specific models to transform the signals
recorded at the surface of the human head into an image. Two categories of model are …

This article reviews recent progress in high-resolution EEG methodologies, in particular two
widely studied approaches: scalp Laplacian mapping and cortical imaging. The common …

While there is a strong interest in meso-scale field potential recording using intracranial
electroencephalography with penetrating depth electrodes (ie stereotactic EEG or S-EEG) in …
