“…The cerebellum plays an important part in the coordination of various neuromuscular activities and in motor learning. It has a role in the control of tone, reinforcing it and thus enabling balance on the one hand and regulation of walking on the other; it participates in the performance of fine voluntary gestures (precision) and in the timing of movements according to Keele, Pokorny, Corcos, and Ivry (1985) and Volman and Geuze (1998). If the cerebellum is affected, this can explain hypotonia, balance disorders, dysdiadochokinesis, and asynergy (of automatic postural responses) and it is also involved in attentional disorders (Fiez, 1996).…”

“…The cerebellum has been implicated in timing through a series of patient studies by Ivry and colleagues (Keele et al, 1985;Spencer et al, 2003;Zelaznik et al, 2005), who have suggested that the cerebellum is particularly involved in event timing (Ivry et al, 2002) -prospective control of the timing of discrete responses. This type of timing would require temporal forward models similar to those required to extrapolate the temporal-spatial trajectory of perceptual stimuli in the present experiment.…”

Prospective (forward) temporal-spatial models are essential for both action and perception, but the literature on perceptual prediction has primarily been limited to the spatial domain. In this study we asked how the neural systems of perceptual prediction change, when change-over-time must be modeled. We used a naturalistic paradigm in which observers had to extrapolate the trajectory of an occluded moving object to make perceptual judgments based on the spatial (direction) or temporal-spatial (velocity) characteristics of object motion. Using functional magnetic resonance imaging we found that a region in posterior cerebellum (lobule VII crus 1) was engaged specifically when a temporal-spatial model was required (velocity judgment task), suggesting that circuitry involved in motor forwardmodeling may also be engaged in perceptual prediction when a model of change-over-time is required. This cerebellar region appears to supply a temporal signal to cortical networks involved in spatial orienting: a frontal-parietal network associated with attentional orienting was engaged in both (spatial and temporal-spatial) tasks, but functional connectivity between these regions and the posterior cerebellum was enhanced in the temporal-spatial prediction task. In addition to the oculomotor spatial orienting network, regions involved in hand movements (aIP and PMv) were recruited in the temporal-spatial task, suggesting that the nature of perceptual prediction may bias the recruitment of sensory-motor networks in orienting. Finally, in temporal-spatial prediction, functional connectivity was enhanced between the cerebellum and the putamen, a structure which has been proposed to supply the brain's metric of time, in the temporal-spatial prediction task.

“…In the ®rst of a series of studies, Keele, Pokorny, Corcos, and Ivry (1985) found that the variances of repetitive tapping with ®nger or foot were correlated across subjects. They were also correlated with performance in a perceptual timing task, where participants judged whether the second of two intervals was shorter or longer than the standard ®rst interval.…”
