The motor system may use internal predictive models of the motor apparatus to achieve better control than would be possible by negative feedback. Several theories have proposed that the cerebellum may form these predictive representations. In this article, we review these theories and try to unify them by reference to an engineering control model known as a Smith Predictor. We suggest that the cerebellum forms two types of internal model. One model is a forward predictive model of the motor… Expand
The Cerebellum as a Predictive Model of the Motor System: A Smith Predictor Hypothesis
The performance of motor systems with large feedback delays can be significantly enhanced by the use of internal predictive representations of the motor apparatus. The cerebellum is a likely site forExpand
Cerebellum Predicts the Future Motor State
TLDR
A synthesis of the evidence suggests that the cerebellum is involved in integrating the current state of the motor system with internally generated motor commands to predict the future state. Expand
Internal models in the cerebellum
TLDR
This review will focus on the possibility that the cerebellum contains an internal model or models of the motor apparatus, and the necessity of such a model and the evidence, based on the ocular following response, that inverse models are found within the Cerebellar circuitry. Expand

I argue that the cerebellum has at least two related roles, both sub-served by its operation as a 'forward model' of the motor system. First, it provides an internal state estimate or sensoryExpand

TLDR
New results show that not all such error information is equivalent in driving cerebellar learning, which is crucial for fast and ballistic movements, but impaired prediction can also affect slow movements, because of increased reliance on time-delayed feedback signals. Expand
Cerebellar patients have intact feedback control that can be leveraged to improve reaching
TLDR
It is shown that the feedback gain in patients with cerebellar ataxia matches that of healthy subjects, but that patients exhibit substantially more phase lag, supporting the predictive role of the cerebellum in feedback control. Expand

Forward modeling allows feedback control for fast reaching movements
TLDR
The ability of the motor system to estimate the future state of the limb might be an evolutionary substrate for mental operations that require an estimate of sequelae in the immediate future. Expand
Contribution of the Cerebellum to Predictive Motor Control and Its Evaluation in Ataxic Patients
TLDR
A non-invasive method to analyze receipt of motor commands in terms of movement kinematics for the wrist joint (Br/Kr ratio) and concludes that the Br/KR ratio of the F1 component provides a unique parameter to evaluate accuracy of the predictive control. Expand
The Cerebellum and the Timing of Coordinated Eye and Hand Tracking
TLDR
Some of the evidence from functional imaging, lesion studies, electrophysiological recordings, and anatomy which support the theory that the cerebellum provides a "forward model" of the motor system are reviewed. Expand

TLDR
It is found that the accuracy in timing motor responses is correlated across different motor effectors, and perceptual acuity in judging durations of auditory intervals is correlated with motoric measures of timing, suggesting a common process underlying timing of different sorts. Expand

How the cerebellum could memorise movements
TLDR
A new way by which the cerebellum could be used for storing information relating to movements, based on the postulate that the signals relating to motor output have been computed in the cerebral cortex and transmitted from there to the Cerebellum for storage. Expand

Abstract First some previous theories of cerebellar function are reviewed, and deficiencies in how they map onto the neurophysiological structure are pointed out. I hypothesize that the cerebellarExpand
Dynamical neural network organization of the visual pursuit system

In the process of constructing a model for the controller, it is shown that two previous pursuit-system models are equivalent from an input-output standpoint and a controller model possessing a potentially highly parallel implementation is introduced. Expand

TLDR
It is proposed formally, and demonstrated by computer modeling, that the firing frequencies of individual cells over a cerebellar cortical area may be interpreted as a spatially distributed, finite, series expansion of a time function, which is reconstructed, by summation, in the nucleus where the cortical cells project.

Timing Functions of The Cerebellum
TLDR
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. Expand

It is demonstrated that, in order for the learning process to be stable, pattern storage must be accomplished principally by weakening synaptic weights rather than by strengthening them. Expand
Purkinje cell activity during motor learning
TLDR
Results are consistent with theoretical proposals that motor learning takes place in the cerebellum through changes in the strength of transmission of parallel fiber synapses on P-cells caused by the climbing fiber input and suggest that climbing fiber firing causes a decrease in thestrength of parallel Fiber synapses.

One area of the brain which seems particularly promising is the cerebellum, and there is a good chance that neuroscientists will benefit from their input of fresh ideas and techniques with which to attack the problems of understanding neural processing. Expand
