Estructura y función del cerebelo

摘要: Introduction The cerebellum is a neural structure, of crystalline like organization, present in all vertebrates. Its progressive growth from fishes to mammals, and particularly primates, takes place following the repetition primitive cellular plan connectivity. Development organized folia located one behind other rostrocaudal axis, placed transversally on brain stem. cerebellar cortex has five types neuron: Purkinje, stellate, basket, Golgi granule cells. Apart cells, cell are inhibitory nature. Afferent fibers two (mossy climbing) carry information somatosensory, vestibular, acoustic visual origins, as well cerebral stem spinal motor centers. only output represented by Purkinje axons that synapse underlying deep nuclei. Cerebellar nuclei send their towards many centers and, thalamic relay nuclei, act different cortical areas. Functionally, seems be small modules, similar but origin end afferent efferent fibers. involved coordination or integration cognitive processes. Conclusion Although lesion does not produce severe paralysis, loss sensory inputs definite deficits functions, its certainly affects performance specific perceptive phenomena.
