Principal components analysis has been a widely used method for the analysis of eventrelated, electrical brain potentials (ERPs). Recent emphasis has been placed on measuring the topography of ERPs, as derived from the instantaneous measurements from multiple locations, and on defining diagnostic di

β¦ Synopsis
The purpose of this article is to present some useful mathematical models for the analysis of multiple electrode event-related brain potential (ERP) experiments. We describe a multivariate spectral method for eye-movement removal and we also describe a multivariate spectral method for the analysis of multiple lead repeated measures data. The complex T' and the complex Behrens-Fisher Problem are also discussed. All of the above methods are applied to experimental ERP data for four electrodes, two groups and two repeated factors.

There is uncertainty concerning the extent to which the auditory streaming effect is a function of attentive or preattentive mechanisms. The mismatch negativity (MMN), which indexes preattentive acoustic processing, was used to probe whether the segregation associated with the streaming effect occur
While dopaminergic, noradrenergic, cholinergic and gabaergic eects on the P300 component of the human eventrelated brain potential have been largely described, little is known about serotonergic inΒ―uence.

Short time Fourier power spectra yield activity related data of the EEG. The mean power densities of frequency bands have proved a reliable descriptive parameter of that activity. Due to their distributional properties of these data their analysis by conventional statistics is restricted to nonparam
