Spatial patterns in resting-state fMRI: networks and parcels

MSDL networks

MSDL networks

Brain functional networks and parcels can extracted from resting-state fMRI. For this purpose we use a multi-subject version of sparse dictionary learning and estimate a group-level atlas of brain networks. This can be understand as a variant of ICA based on the assumption of sparsity rather than independence.

Download MSDL Atlas

The functional regions defined by this approach can be downloaded in the following reference atlas [Varoquaux et al 2011].

Application in connectomics

These regions can be used to define the nodes of a functional connectome, as in [Varoquaux & Craddock 2013].
