The 21^st Century Cerebellum: An Evolution of Cognitive Functions, Connections, Disorders, and Pharmacotherapeutic Modulation

Our understanding of the cerebellum’s role in health and disease has evolved considerably in the past few decades; largely due to the availability of newer and better modalities for studying the relationships between the cerebellum and other segments of the brain, and how these impact behavioural responses like motor function, emotionality, memory and more recently, cognition. In this review, we discuss the evolution of our understanding of the structure and function of the cerebellum; where we were, and how we got here. We also examine the important roles of the cerebellum in neuro-cognitive processing, cognition and cognitive disorders; and ponder on how targeting cerebellar cognition may open a new chapter in the quest for the development and identification of newer cognition-modulating agents
