摘要：

The somatosensory ( haptic) vertical ( HV) and visual vertical ( VV) were assessed in two patients with vestibular nuclear lesions. Patient 1 had paroxysmal nystagmus, and was tested " on" and " off." The HV was normal " on" and " off " but the VV was severely tilted during vestibular paroxysms. Patient 2, with a brainstem stroke, was tested at months 1 and 6. The VV was severely tilted on both occasions ( > 12 degrees) but the HV was marginally tilted ( 4 degrees) in the acute stage only. These VV- HV dissociations suggest that vestibular nuclear lesions influence gravity perception mostly via ocular torsional effects rather than by disrupting a single, internal representation of verticality.
