Spatio-Spectral Mixed-Effects Model for Functional Magnetic Resonance Imaging Data

The goal of this article is to model cognitive control related activation among predefined regions of interest (ROIs) of the human brain while properly adjusting for the underlying spatio-temporal correlations. Standard approaches to fMRI analysis do not simultaneously take into account both the spa...
