Figures from this paper

Cerebellum and Timing 52
TLDR
The timing hypothesis provides a parsimonious account of the cerebellar contribution to sensorimotor learning and highlights some of the limitations of Cerebellar timing.
Interval time coding by neurons in the presupplementary and supplementary motor areas
TLDR
Neuronal activity contributed to the process of retrieving time instructions from visual cues, signaled the initiation of action in a time-selective manner, and developed activity to represent the passage of time.
Timing in the Absence of Clocks: Encoding Time in Neural Network States
Population clocks: motor timing with neural dynamics
A Unified Model for the Neural Bases of Auditory Time Perception
TLDR
A unified model of time perception is proposed to involve serial beat-based striatal activation followed by absolute olivocerebellar timing mechanisms with a central role for the striatum as the brain’s internal timekeeper.
A Unified Model of Time Perception Accounts for Duration-Based and Beat-Based Timing Mechanisms
TLDR
A unified model of time perception based on coordinated activity in the core striatal and olivocerebellar networks that are interconnected with each other and the cerebral cortex through multiple synaptic pathways is proposed.
Cerebellum and the deciphering of motor coding
TLDR
Scientists working on the field of motor control are gathered to provide an overview of recent advances in understanding of the contribution of this remarkable circuitry in the elaboration and shaping of motor commands.
A Neural Correlate of the Processing of Multi-Second Time Intervals in Primate Prefrontal Cortex
TLDR
A group of PFC neurons in area 9 that became active when monkeys recognized a particular elapsed time within the range of 1–7 seconds are described, suggesting that area 9 may process multi-second intervals not only in perceptual recognition, but also in internal generation of time intervals.
A tRNS investigation of the sensory representation of time
TLDR
The results of the present study confirm that the right posterior parietal cortex is involved in the processing of time intervals and extend this finding to several sensory modality conditions.
Parietal Cortex Signals Come Unstuck in Time
TLDR
Previous work on parietal cortex and time perception is described, and the findings of a study published in this issue of PLOS Biology, in which Schneider and Ghose characterize single-neuron responses during performance of a novel “Temporal Production” task are highlighted.

Context‐related representation of timing processes in monkey motor cortex
TLDR
Compared the activities of neurons recorded in monkey motor cortex during the performance of two tasks requiring correct time estimation in different contextual situations indicates that time is indeed represented in neuronal activity of the motor cortex, albeit strongly dependent on context and not in an invariant manner as a distinct process per se.

What the cerebellum computes
Neural Network Model of the Cerebellum: Temporal Discrimination and the Timing of Motor Responses
TLDR
A neural network model based on the synaptic organization of the cerebellum that can generate timed responses in the range of tens of milliseconds to seconds is described and is demonstrated that the population vector of simulated granule cell activity exhibits dynamic, nonperiodic trajectories in response to a periodic input.
The roles of the cerebellum and basal ganglia in timing and error prediction
TLDR
It is shown that the cerebellum is primarily activated with timing irregularity while the anterior striatum is activated with task order unpredictability, supporting their distinctive roles in two forms of readjustment.
The Cerebellum and Event Timing
Abstract: Damage to the cerebellum disrupts performance on a range of tasks that require precise timing including the production of skilled movements, eyeblink conditioning, and perceptual tasks such
Activation of the supplementary motor area and of attentional networks during temporal processing
TLDR
It is argued, firstly, that involvement of the attentional areas derives from specific relations between attention and the temporal accumulator, as described by dominant timing models; and, secondly, that the SMA, or more probably one of its subregions, subserves time processing.
Distinct systems for automatic and cognitively controlled time measurement: evidence from neuroimaging
Cortical Networks Underlying Mechanisms of Time Perception
TLDR
Results implicate a right hemisphere prefrontal–inferior parietal network in timing and suggest time-dependent attention and working memory functions may contribute to temporal perception deficits observed after damage to this network.
