Testing the determinism of EEG and MEG

Testing the determinism of EEG and MEG.

NEURAL MASS ACTIVITY produces irregular time series such as the EEG and MEG. It is already apparent, through visual inspection, that these time series cannot simply result ...J from an uncoordinated arbitrary firing of neurons. Indeed, we expect that neurons must cooperate and partially synchronize their firing patterns in order to produce meaningful output. Although we may believe that we have...

Nonparametric statistical testing of EEG- and MEG-data.

In this paper, we show how ElectroEncephaloGraphic (EEG) and MagnetoEncephaloGraphic (MEG) data can be analyzed statistically using nonparametric techniques. Nonparametric statistical tests offer complete freedom to the user with respect to the test statistic by means of which the experimental conditions are compared. This freedom provides a straightforward way to solve the multiple comparisons...

EEG/MEG Signal Processing

Since its invention by the Hans Berger of the electroencepha-lography (EEG) in 1929, it was a strong scientific curiosity in analysis of human brain activity. In fact, the electroen-cephalography (EEG) and magnetoencephalography (MEG) have developed into one of the most important and widely used quantitative diagnostic tools in analysis of brain signals and patterns. EEG and MEG potentially con...
