Visual modulation of neuronal activity within the rat vestibular nuclei. 1983

K M Horn, and S W Miller, and H C Neilson

Sixty-two of 95 units within the vestibular nuclei of 24 hooded, Long-Evans rats were found to respond to both linear accelerations on a parallel swing and to linear movements of the visual field. The addition of visual clues during periods of linear accelerations produced a phase shift in the majority of the units towards the maximal acceleration of the animal, and an increase in the peak activity during the periods of maximal acceleration. Conflicting visual-vestibular stimulation resulted in reduced directional sensitivity and lower rates of firing in visually sensitive units.

D014722	Vestibule, Labyrinth	An oval, bony chamber of the inner ear, part of the bony labyrinth. It is continuous with bony COCHLEA anteriorly, and SEMICIRCULAR CANALS posteriorly. The vestibule contains two communicating sacs (utricle and saccule) of the balancing apparatus. The oval window on its lateral wall is occupied by the base of the STAPES of the MIDDLE EAR.
