Dense array EEG (dEEG) source estimation in neocortical epilepsy [PDF]
Frontiers in Neurology, 2013 Rationale : Dense array EEG (dEEG) evenly covers the whole head surface with over 100 channels contributing to more accurate electrical source imaging due to the higher spatial and temporal resolution.

Influence of dense‐array EEG cap on fMRI signal [PDF]
Magnetic Resonance in Medicine, 2012 AbstractDense‐array (>64 channel) electroencephalography (EEG) systems are increasingly being used in simultaneous EEG–functional magnetic resonance imaging (fMRI) studies. However, with increasing channel count, dense‐array EEG caps can induce more severe signal dropout in the MRI images than conventional systems due to the radiofrequency shielding

Statistical control of artifacts in dense array EEG/MEG studies [PDF]
Psychophysiology, 2000 With the advent of dense sensor arrays (64–256 channels) in electroencephalography and magnetoencephalography studies, the probability increases that some recording channels are contaminated by artifact. If all channels are required to be artifact free, the number of acceptable trials may be unacceptably low. Precise artifact screening is necessary for

COMPLEXITY QUANTIFICATION OF DENSE ARRAY EEG USING SAMPLE ENTROPY ANALYSIS
Journal of Integrative Neuroscience, 2004 In this paper, a time series complexity analysis of dense array electroencephalogram signals is carried out using the recently introduced Sample Entropy (SampEn) measure. This statistic quantifies the regularity in signals recorded from systems that can vary from the purely deterministic to purely stochastic realm.

, 2011 Electroencephalographic (EEG) signals derive from the action of neuronal activity in the cerebral cortex, through the action of synchronously occurring post-synaptic potentials of neuronal masses (De Munck et al., 1992). Forming reciprocal combinations of interacting excitatory and inhibitory populations, these neuronal masses are believed to be the ...

Integrating dense array EEG in the presurgical evaluation of temporal lobe epilepsy. [PDF]
ISRN Neurol, 2012 Purpose. To evaluate the clinical utility of dense array electroencephalography (dEEG) for detecting and localizing interictal spikes in temporal lobe epilepsy. Methods. Simultaneous invasive and noninvasive recordings were performed across two different groups.

Localizing movement-related primary sensorimotor cortices with multi-band EEG frequency changes and functional MRI. [PDF]
PLoS ONE, 2014 Electroencephalographic (EEG) oscillations in multiple frequency bands can be observed during functional activity of the cerebral cortex. An important question is whether activity of focal areas of cortex, such as during finger movements, is tracked by ...
