Patients with cerebellar damage are known to exhibit deficits in the temporal control of movements. We report that these deficits are restricted to discontinuous movements. Cerebellar patients exhibited no deficit in temporal variability when producing continuous, rhythmic movements. We hypothesize that the temporal properties of continuous movements are emergent and reflect the operation of other control parameters not associated with the cerebellum. In contrast, discontinuous movements… 
Timing of rhythmic movements in patients with cerebellar degeneration
Results of a new experiment in which individuals with cerebellar ataxia produced rhythmic tapping or circle drawing movements provide further evidence that the integrity of the cerebellum is especially important for event timing, although the attempt to specify the relationship between event and emergent timing was not successful.
Role of the cerebellum in movements: control of timing or movement transitions?
The results of the present experiments are consistent with the hypothesis that the cerebellum is essential for tasks requiring precise event-like temporal control, and support the transition hypothesis.
Cerebellar activation during discrete and not continuous timed movements: An fMRI study
Reversible block of cerebellar outflow reveals cortical circuitry for motor coordination
Results indicate that the timing of actions, but not the selection of muscles, is regulated through cerebellar control of motor cortical activity, which organizes execution-related activity of a motor cortical subnetwork.
Dissociating Timing and Coordination as Functions of the Cerebellum
It is suggested that timing and coordination are behaviorally distinct modes of motor control and that the anterior cerebellum is a crucial node in state-dependent motor control, computing a predictive state estimate of one effector to coordinate actions of another effector.
Spontaneous, synchronized, and corrective timing behavior in cerebellar lesion patients
Coupling between cerebellar hemispheres: Behavioural, anatomic, and functional data
Behaviour, functional, and anatomic data are reviewed to shed light on possible interactions between both cerebellar hemispheres during the execution of timed motor behaviour and reduce timing variability during simultaneous bimanual tasks.


Callosotomy patients exhibit temporal uncoupling during continuous bimanual movements
This work proposes a subcortical locus of temporal coupling for movements involving discrete events, and reports that such coupling is restricted to movements entailing a discrete event (such as a movement onset).
Dissociation of the lateral and medial cerebellum in movement timing and movement execution
It is concluded that the lateral regions of the cerebellum are critical for the accurate functioning of an internal timing system.
Timing Functions of The Cerebellum
The results suggest that the domain of the cerebellar timing process is not limited to the motor system, but is employed by other perceptual and cognitive systems when temporally predictive computations are needed.
Deficit in classical conditioning in patients with cerebellar degeneration.
There is evidence from animal experiments that the cerebellum and its associated brainstem circuitry are involved in the acquisition of the conditioned response. In order to obtain evidence for their
Classical conditioning after cerebellar lesions in humans.
Results are consistent with animal studies and earlier case reports indicating that intact cerebellar structures are necessary for the acquisition of classically conditioned motor responses.
Cerebellar involvement in eyeblink classical conditioning in humans.
The role of the ipsilateral cerebellum in human eyeblink conditioning was investigated using the 400-ms delay paradigm and testing 14 cerebellar patients (7 with unilateral lesions and 7 with
Localization of a cerebellar timing process using PET
It is concluded that the cerebellum is involved in time-critical perception ( ``timing'') and this nonmotor task can be separated from a motor task (finger movement).
Human cerebellum plays an important role in memory-timed finger movement: an fMRI study.
The results indicate that the anterior lobe of the cerebellum of both sides, the SMA, and the left prefrontal cortex were probably involved in the generation of accurate timing, functioning as a clock within the CNS, and that the dorsal visual pathway may be involved inThe generation of visually cued movements.
Categorical Speech Perception in Cerebellar Disorders
The data corroborate the hypothesis of the cerebellum as an internal clock and implicate a role of this structure in speech perception and corroborates the hypothesis that the processing of durational parameters of the perceived acoustic speech signal such as voice onset time depends upon this structure.
