Neural Representation of Time and Timing Processes
TLDR
Evidence has indicated that similar brain structures are involved in both subsecond and suprasecond timing, implicating that temporal processing in these two ranges is probably mediated by common neural networks.
The neural representation of time
A right hemispheric prefrontal system for cognitive time measurement
Spatial–temporal interactions in the human brain
TLDR
Neuroimaging and neuropsychological findings point towards the posterior parietal cortex as the main site where spatial and temporal information converge and interact with each other, similar to what is reported for other ordered quantities, such as numbers.
Common neural mechanisms for explicit timing in the sub-second range
TLDR
The supplementary motor area and the basal ganglia are suggested as the common neural substrates for temporal processing across sensory modalities and sensory structures for explicit timing in the subsecond range.
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.
Intelligence and Variability in a Simple Timing Task Share Neural Substrates in the Prefrontal White Matter
TLDR
These results suggest a bottom-up explanation of the link between temporal stability and intellectual performance, in which more extensive prefrontal connectivity underlies individual differences in both variables.
Timing of covert articulation: An fMRI study
Magnitude Processing in the Brain: An fMRI Study of Time, Space, and Numerosity as a Shared Cortical System
TLDR
It is argued that the intraparietal sulcus, insula, premotor cortex/SMA, and inferior frontal gyrus comprise a distributed magnitude processing system and further research of this system may provide insight into the etiology of neurodevelopmental disorders where cognitive deficits in magnitude processing are manifest.

Time Perception and Motor Timing: A Common Cortical and Subcortical Basis Revealed by fMRI
TLDR
Findings show that the neural network supporting time perception involves the same brain areas that are responsible for the temporal planning and coordination of movements, indicating that time perception and motor timing rely on similar cerebral structures.

Cerebral correlates of working memory for temporal information
TLDR
Using fMRI to explore brain areas that underlie different working memory operations directed to the temporal domain, significant activations related to memory updating and comparison processes were found right-accentuated in prefrontal and lateral premotor cortices.

The evolution of brain activation during temporal processing
TLDR
A dynamic network of cortical-subcortical activation associated with different components of temporal information processing is illustrated, implicating these systems in attention and temporary maintenance of intervals.
Functional Localization of a “Time Keeper” Function Separate from Attentional Resources and Task Strategy
TLDR
Results revealed lateral cerebellar and inferior temporal lobe activation were associated with primary time keeping, consistent with prior proposals that the cerebellum is a repository of codes for time processing, but also implicate temporal lobe structures for this type of time estimation task.

Cortical Networks Recruited for Time Perception: A Monkey Positron Emission Tomography (PET) Study
TLDR
The results indicate that a neural network composed of the posterior inferior parietal cortex to the DLPFC plays a crucial role in the temporal monitoring process in time perception.
The human cerebellum and temporal information processing--results from a PET experiment.
TLDR
The cerebellum is involved in temporal information processing even in the absence of motor output, and this process can be separated from mere presentation of somatosensory stimuli.
Brain activity during non-automatic motor production of discrete multi-second intervals
TLDR
The result shows that, in time measurement, medial premotor activation is not specific to automatic movement, and DLPFC activity is not Specific to non-motor tasks.
