Lesions involving the velocity\u2010storage circuit give rise to positional vertigo and nystagmus. Herein, we present a 32\u2010year\u2010old 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\u2010storage 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\u00a0position. This report expands the spectrum of central positional nystagmus due to dysfunction of the velocity\u2010storage mechanism.<\/jats:p>","DOI":"10.1002\/acn3.51883","type":"journal-article","created":{"date-parts":[[2023,8,22]],"date-time":"2023-08-22T02:21:59Z","timestamp":1692670919000},"page":"1931-1936","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Periodic
