[Autonomy of the centers of otolithic nystagmus]

Pigeons (Columba livia) with unilaterally sectioned saccular nerves (Ramuli sacculi) were rotated in the dark along the horizontal plane. The nystagmic reaction which developed when the vestibular apparatus was simultaneously exposed to otolith and canal stimuli, each of which taken separately caused nystagmus of the same direction, was less pronounced in the case of canal stimulation. This can be regarded as evidence indicating autonomicity of otolith nystagmus centers.
