摘　　要：The role of intercalatus nucleus of Staderini(INS),the most caudal of the perihypoglossal nuclei,is much debated.Last research seems to suggest that this nucleus plays a role as a vertical eyes movements integrator.The few clinical reports present in the literature that describe isolated lesions of the INS have described patients presenting in acute with up-beating vertical spontaneous nystagmus.Isolated acute lesion of INS is,in fact,much rare,and,without other neurological signs,is exceptional.We present a case of acute isolated vertigo with no other neurological signs or symptoms,due to INS ischemia provoked by vertebral artery stenosis.The patient presented with spontaneous vertical up-beating nystagmus that showed at videonystagmographic recording,a clear exponential decay of angular slow-phase velocity,that is considered a typical sign of neural integrator impairment.This case seems to represent a further confirm that INS is part,as a vertical-to-position neural integrator,of the neural circuit controlling the vertical eyes movements.
