Spatiotemporal Analysis of Multichannel EEG: CARTOOL

This paper describes methods to analyze the brain's electric fields recorded with multichannel Electroencephalogram (EEG) and demonstrates their implementation in the software CARTOOL. It focuses on the analysis of the spatial properties of these fields and on quantitative assessment of changes of field topographies across time, experimental conditions, or populations. Topographic analyses are ...

Maximum likelihood spatiotemporal EEG/MEG source analysis

EEG/MEG noise has an unequal variance and is correlated, both in space and in time. Noise variance may differ greatly between samples or sensors, and correlations between samples or sensors can be very high [1-4]. If these noise characteristics are neglected, then an EEG/MEG source analysis will yield unreliable results [e.g. 5, 6]. First, source parameter estimates will be inefficient. That is...

Multichannel Classification of Single EEG Trials with Independent Component Analysis

We have previously shown that classification of single-trial electroencephalographic (EEG) recordings is improved by the use of either a niultichannel classifier or the best independent component over a single channel classifier. In this paper, we introduce a classifier that makes explicit use of multiple independent components. Two models are compared. The first ("direct") model uses independe...

Study of Correlations of Multichannel Human EEG

Contained in this paper are preliminary results in describing the multichannel human EEG data by measures of correlation. It is investigated if linear cross-correlation measures such as Pearson’s r, Spearman’s ρ, and Kendall’s τ would give the same information of correlation. The EEG data were recorded from 11 healthy adult human subjects, taken in two conditions: resting eyes closed and restin...

Pre-reflective and reflective self-reference: A spatiotemporal EEG analysis

Functional imaging studies consistently support the role of the medial prefrontal cortex to be a part of a functional network of reflective self-awareness. The current study introduces a new linguistic task which (1) directly compares self-reference and other-reference, and (2) separates pre-reflective from reflective aspects of self-awareness. Twenty-six healthy volunteers evaluated trait adje...
