title: Is tremor an inherent feature of an intact but misadjusted motor control system?
abstract: Coordination of voluntary discrete motor responses with ongoing background activity like tremor is investigated for the single-muscle multiple-task condition by experimental and theoretical work. It is shown that the periodic background activity entrains the discrete responses. The experimental results are described by a model of the motor execution stage, and several possible consequences of the model for the motor behavior in Parkinsonian tremor patients are discussed.
