The vestibular cortical projection during spinal decompensation

The vestibular cortical projection during spinal decompensation

Archives Italiennes de Biologie 124(1): 15-26

The removal of spinal afferents in rabbits submitted to unilateral lesion of the labyrinth and fully compensated greatly modified the field potentials as well as the single unit responses recorded from the cortical vestibular area during stimulation of the intact eighth nerve. In particular, an increase of contralateral and a decrease of ipsilateral potentials were observed. These asymmetrical responses indicate that the influence of the spinal cord in compensating the effects of unilateral lesion of the labyrinth is directed to balance not only the electrical activity of the brain-stem structures, but also that of the cerebral cortex. It appears, therefore, that spinal signals intervene not only in the compensation of vestibulospinal and vestibulo-oculomotor functions but also of cortical functions, such as that related to vestibular sensation.
