This updated reference covers diverse aspects of cerebellar development from a full range of viewpoints, including the epidemiology of cerebellar genetic disorders, developmental anatomy, cell biology, genetics, epigenetics, infectious diseases, and mechanisms involved in the regulation of cell fate, while also focusing on information that is relevant to clinicians caring for patients with cerebellar disorders. The chapters are written by experts in the field of cerebellar development, and the chapters cover diseases related to the cerebellum, along with their epidemiology, clinical features, assessment, and management. In addition to updating the content to cover the significant developments in the field since the first edition, the second edition will include new chapters on Non-Coding RNAs and Cerebellar Development, Development of the Fish Cerebellum, the Role of nNOS/NO on Cerebellar Development in Health and Disease, and rehabilitation in cerebellar ataxia. The effect of the COVID-19 on the cerebellum has been included in related chapters. Development of the Cerebellum from Molecular Aspects to Diseases, 2nd edition, is designed to be valuable reference for both neuroscientists and clinicians.
