Bayes' Rule is often written as p([theta]|y) [varies] p([theta])p(y|[theta]), when treated as a function of [theta] for a fixed y, and p(y|[theta]) is the likelihood L(y|[theta]).
In order to apply Bayesian analysis to fMRI data and make inference to the parameters that we are interested in, like finding the change points in the dataset, we need to set up a probability model for the data and find a prior to apply Bayes' Rule.
