Norell's research group uses high-resolution CT to peer inside the braincases of extinct dinosaurs, allowing scientists to create digital endocranial casts, called endocasts--detailed, 3D reconstructions of the interiors of fossilized skulls--which they use to examine the size and shape of various brain regions, including the brainstem, which regulates heartbeat, respiration, and other functions; the cerebellum, which coordinates muscle movements; and the cerebrum, which is involved with complex sensory functions and memory.
