Abstract:
Lesion was made individually to the verious cortical areas in 14 adult cats.Thecorticofugal fibers terminating into vestibular nuclei were traced in sections by meansof modified Nauta silver staining method.The majority of cortical efferents which terminated to the vestibular nuclei deri-ved from somato-sensory area Ⅰ.A few fibers originated from the cortical motorareas,and some fibers derived from vestibular area and somatosensory area Ⅱ.Thefibers originated from the visual and auditory areas were not observed.The corticovestibular fibers descended within the pyramidal tract.These fibersleft pyramidal tract at the level of pons.Then,most of them reached to the vesti-bular nuclei ipsilaterally,and others reached bilaterally.Terminal degeneration was present throughout the whole extent of the vestibularnuclei.The total number of preterminal degenerating fibers in the nuclei was small.The anatomical and functional significance of our findings are discussed.
