The function of rapid-eye-movement (REM) sleep is still unknown. One prevailing hypothesis
suggests that REM sleep is important in processing memory traces. Here, using positron …

In rats, the firing sequences observed in hippocampal ensembles during spatial learning are
replayed during subsequent sleep, suggesting a role for posttraining sleep periods in the …

Distributed linear solutions of the EEG source localisation problem are used routinely. In
contrast to discrete dipole equivalent models, distributed linear solutions do not assume a fixed …

In Friston et al. ((2002) Neuroimage 16: 465–483) we introduced empirical Bayes as a potentially
useful way to estimate and make inferences about effects in hierarchical models. In this …

This paper reviews hierarchical observation models, used in functional neuroimaging, in a
Bayesian light. It emphasizes the common ground shared by classical and Bayesian methods …

This paper describes an application of hierarchical or empirical Bayes to the distributed
source reconstruction problem in electro- and magnetoencephalography (EEG and MEG). The …

BACKGROUND: Mechanisms of anesthesia-induced loss of consciousness remain poorly
understood. Resting-state functional magnetic resonance imaging allows investigating whole-…

SPM is a free and open source software written in MATLAB (The MathWorks, Inc.). In
addition to standard M/EEG preprocessing, we presently offer three main analysis tools: (i) …

In perceptual experiments, within-individual fluctuations in perception are observed across
multiple presentations of the same stimuli, a phenomenon that remains only partially …

In humans, some evidence suggests that there are two different types of spindles during
sleep, which differ by their scalp topography and possibly some aspects of their regulation. To …
