The globus pallidus is a structure in the brain involved in the regulation of voluntary movement. It is part of the basal ganglia, which, among many other things, regulate movements that occur on the subconscious level. In this book, the authors present current research in the study of the regional anatomy, functions/dysfunctions and role in behavioral disorders of the globus pallidus. Topics discussed include imaging of the globus pallidus in patients suffering from pantothenate kinase-associated neurodegeneration (PKAN); anatomofunctional territories and pathophysiological relations in the globus pallidus; a population activity model of cortico-striatal circuitry underlying behavioral inhibition in rats; and the neuropathology of the basal ganglia and its role in the Parkinsonian syndromes with special reference to the globus pallidus.
