Main results showed deviant-related responses that generalize across two types (stimulus probability and sequence structure) in the LC but also many subcortical regions, including neuromodulatory centers, several cortical regions, and the pupil.

We used fMRI optimized for brainstem imaging with pupillometry to perform a mapping of deviant-related responses in subcortical structures. Subjects had to detect deviant items in the “local-global” task (with deviant based on the stimulus probability and the sequence structure.
