Statistical Control of Artifacts in Dense Array EEG/MEG Studies [PDF]

open access: yesPsychophysiology, 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

Dense Array EEG: Methodology and New Hypothesis on Epilepsy Syndromes

Epilepsia, 2008
Summary Dense array EEG is a method of recording electroencephalography (EEG) with many more electrodes (up to 256) than is utilized with standard techniques that typically employ 19–21 scalp electrodes. The rationale for this approach is to enhance the spatial resolution of scalp EEG.

Complexity Quantification of Dense Array EEG Using Sample Entropy Analysis.

open access: yesJournal 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.

Geodesic Photogrammetry for Localizing Sensor Positions in Dense-Array EEG

Clinical Neurophysiology, 2005
An important goal for functional brain studies using EEG technology is to estimate the location of brain sources that produce the scalp-recorded signals. The accuracy of source estimates is dependent upon many variables, one of which is the accurate description of the scalp positions of the EEG sensors.
