Cerebellar Influences on Descending Spinal Motor Systems

摘要: The cerebellar nuclei, and to some extent the vestibular mediate ultimate result of processing rest brain. Cerebellar output is directed diencephalon a score brainstem regions. This chapter reviews nuclear projections areas that give rise descending connections can influence motor programming at spinal cord level, i.e., reticulospinal, vestibulospinal, rubrospinal, tectospinal, interstitiospinal pathways. In addition, other will be briefly considered. Although structured by modular internal organization circuitry related olivocerebellar connections, it concluded output, is, individual nuclei or parts thereof, still reaches many in diencephalon. multiple modules may converge their outputs indirectly same muscles. suggests modulesmay each take part different aspects control muscle group. Conversely, modules, due distributed nature outputs, simultaneously affect several systems with ensuing goal. More detailed anatomical physiological studies necessary explore these possibilities.
