We present a model that describes the structure in the responses of different brain areas to a set of stimuli in terms of <i>stimulus categories</i> (clusters of stimuli) and <i>functional units</i> (clusters of voxels). We assume that voxels within a unit respond similarly to all stimuli from the same category, and design a nonparametric hierarchical model to capture inter-subject variability among the units. The model explicitly encodes the relationship between brain activations and fMRI time ...[more]
