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 nuclea...
