Functional connectivity between brain regions is modulated by cognitive states or experimental conditions. Such connectivity variations can be appreciated in covariance or correlation matrices obtained from fMRI data. A multivariate methodology that can capture fMRI connectivity maps in light of different experimental conditions would be of primary importance to learn about the specific roles of the different brain areas involved in the observed connectivity variations. Here we introduce Spatial...

We perform a comprehensive integrative analysis of multiple structural MR-based brain features and find strong evidence relating inter-individual structural variations to demographic and behavioral variates across a large cohort of healthy human volunteers. In particular, our findings shed some light on functional & structural integration, as we find a mode of structural variation that relates to and extends the positive-negative behavioral spectrum which was recently reported as being associate...

We present a novel sparse dimensionality reduction approach to reconstruct biological signals for brain computer interfaces (BCI). The proposed technique may be used in the design of an adaptive Brain Computer Interface which uses interaction error potentials.
