High frequency oscillation of somatosensory evoked field in patients with unilateral cerebellar lesion

摘要

It is well known that cerebellar hemishere affects contralateral primary motor area, causing ataxia. Recently, some reports suggest that cerebellum also effects on low frequency component of somatosensory evoked responses (1,2). In order to examine whether this effect exists also in high frequency oscillation (HFO), somatosensory evoked field (SEF) was recorded in unilateral cerebellar patients.
