title: Rediscovery of an early concept.
abstract: The study of the cerebellum has been dominated by interest in its role in movement and motor control. From the earliest days of the neuroscientific era, however, clinical reports and physiological and behavioral investigations have suggested that overt motor dysfunction is but one manifestation of cerebellar disease. The nature of cerebellar involvement in autonomic, sensory, and cognitive functions has been investigated for many years, and possible mechanisms that could subserve this relationship have been specifically addressed. This work has not been incorporated into the mainstream of neuroscience or clinical neurological thinking. This chapter traces the history of these early investigations that demonstrated the need to revise the notion that cerebellar function is confined to the motor realm. The collaboration across disciplines and the advances in the methods and concepts of contemporary neuroscience have facilitated the maturation of this field of inquiry. The "new" story of the cerebellum and cognition, in fact, represents the evolution of a century-old revolutionary concept.
