Effects of body to head rotation on the labyrinthine responses of rat vestibular neurons

Highlights • Neck rotation modifies vestibulospinal reflexes through the cerebellum. • Labyrinthine responses of vestibular and reticular neurons are tuned by neck rotation. • Neck rotation modifies labyrinthine response directions in the cerebellum. • Neck rotation modifies labyrinthine response ga...

Description
Summary:Highlights • Neck rotation modifies vestibulospinal reflexes through the cerebellum. • Labyrinthine responses of vestibular and reticular neurons are tuned by neck rotation. • Neck rotation modifies labyrinthine response directions in the cerebellum. • Neck rotation modifies labyrinthine response gains and basal activity in the vestibular nuclei and in the reticular formation. • The role of the cerebellum in this transformation has to be reconsidered.
