Response Characteristics of Central Vestibular Neurons and Compensatory Mechanisms following Hemilabyrinthectomy
Response Characteristics of Central Vestibular Neurons and Compensatory Mechanisms following Hemilabyrinthectomy
The changes in vestibular neuronal activities that accompany hemilabyrinthectomy (HL) are the main focus of this study. The emphasis is on the acute and chronic changes in relation to the otolith system in response to HL. The compensatory process after HL is also discussed in relation to the involvement of neural structures and changes in synaptic mechanisms. The semicircular canal system and the otolith system are discussed in this chapter. The acute hemilabyrinthectomy, otolith function with bilateral labyrinths intact, and the response sensitivity and spatial coding properties of central vestibular units in the lesioned side are also described. The findings imply that inputs from the intact otoliths and/or semicircular canals in the lesioned animals are operative at the level of the vestibular nuclei bilaterally during natural head movements.
