ABSTRACT

Neuroimaging, particularly functional magnetic resonance imaging (fMRI), is a useful and increasingly popular tool for studying the brain activity dynamics underlying human psychology. fMRI data consist of brain images — approximately 100,000 brain voxels (cubic volumes that span the three-dimensional space of the brain) — measured repeatedly every 2 sec or so, with images nested within task conditions and conditions nested within participants. Analysis of these complex data sets is the focus of intensive research and development in the scientific community.
