“…Herein, we present a 32‐year‐old man with cerebellar nodulus and uvular hemorrhage who showed periodic vertigo and downbeat nystagmus in the supine position. To explain this unusual pattern, we adopted velocity‐storage model with a lesion on the neural connection between the gravity and inertia estimators, resulting in periodic neural impulses and a gravity bias in a specific position. …”

“…Contralateral and monocular downbeat nystagmus is very rare. Our case suggests that the present downbeat nystagmus was due to dysfunction of cerebellar-modulated crossed oculovestibular fibers of the superior cerebellar peduncle or bilateral downbeat nystagmus with one-sided oculomotor nerve palsy.…”
