Figure 4.
Author-topic model for discovering co-activation patterns of the inferior frontal junction (IFJ). In contrast to Figure 2, this instantiation of the model assumes that each experiment constitutes a unique task. The premise of the model is that the IFJ expresses multiple overlapping task-dependent co-activation patterns. The model parameters are the probability of an experiment recruiting a co-activation pattern (Pr(co-activation pattern | experiment)), and the probability of a voxel being associated with a co-activation pattern (Pr(voxel | co-activation pattern)).
