CNS vs. Semi-circular canals[edit]

the section on + test states that up and down nystagmus results from a cns lesion. then it goes on to further localize these to particular semi-circular canals. do you the canals to be part of the cns? i've always considered tyhem part of the inner ear, which, in turn, i don't think of as the cns. clarify? correct me? —Preceding unsigned comment added by Toyokuni3 (talkcontribs) 19:26, 15 May 2008 (UTC)

From a clinical (i.e. physician's) viewpoint, CNS here means brain, and SCC means peripheral. CNS localization implies that I need to target the brain for further workup, e.g. MRI. Pollira (talk) 19:06, 14 December 2014 (UTC)

Which ear affected with downbeat nystagmus. Probable error.[edit]

when the left ear (for example) is down during the Dix-Hallpike maneuver, the posterior semicircular canal is in the vertical plane, and upbeating + torsional nystagmus is caused by BPPV in the left posterior SCC. However, the RIGHT (contralateral) ANTERIOR SCC is also in the vertical plane, and downbeating + torsional nystagmus would be attributed to RIGHT sided anterior SCC BPPV. The text here is in error.
