Exploring Brain Structures with Lesion Work and Neural Imaging for Movement Control

Explore how brain structures involved in movement control are studied through lesion work, neural imaging like CAT, PET, and fMRI, and transcranial magnetic stimulation (TMS) with a focus on the cerebellum's role in paced finger tapping. Understand how neural control of movement involves both higher centers and spinal cord mechanisms.
