Voluntary palatal tremor is associated with hyperactivation of the inferior olive: a functional magnetic resonance imaging study.
Voluntary palatal tremor in a patient with essential palatal tremor induced activation predominantly within regions corresponding to the inferior olive, adjacent brainstem, and dentate nuclei. Finger movements elicited only ipsilateral lobular cerebellar activation, suggesting a dysfunctional nuclear activation by palatal tremor.
