Comparison of the Motor System – Brain Dissections. The video compares the three major motor systems and focuses on categorizing motor problems as corticospinal tract, cerebellar, or basal ganglia. It begins with 12 minutes of gross anatomical structures and pathway review followed by clinical video clips demonstrating clinical features of disease of each of the three major circuits. Clinical signs and symptoms include: hemiparesis, spasticity, Babinski, clonus, atrophy, fasciculations, limb ataxia, dysmetria, intention tremor, rapid alternating movements, pendular reflexes, hypotonia, titubation, nystagmus, resting tremor, bradykinesia, athetosis, chorea, tardive dyskinesia, rigidity and retropulsion. With English or Italian closed captions. Video by Suzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy, University of Utah School of Medicine.
