Distinct systems for automatic and cognitively controlled time measurement: evidence from neuroimaging.
TLDR
It is argued that careful analysis of this literature provides evidence for separate neural timing systems associated with opposing task characteristics, the 'automatic' system draws mainly upon motor circuits and the 'cognitively controlled' system depends upon prefrontal and parietal regions.About:

Dissecting the clock: understanding the mechanisms of timing across tasks and temporal intervals.
TL;DR: Differences across tasks suggests that task demands influence the mechanisms that are engaged for keeping time, and the popular dedicated scalar model of timing accounts for performance across a restricted timescale surrounding the 1-second duration for different tasks.

Segregated and overlapping neural circuits exist for the production of static and dynamic precision grip force

TL;DR: These findings provide the first neuroimaging evidence supporting a lateralized pattern of brain activity for the production of static and dynamic precision grip force.
Journal ArticleDOI
A neurocomputational model for optimal temporal processing.
TL;DR: A neuronal model is offered which explains the form of the error function as a result of a constrained optimization process and shows how this optimal selection could be implemented by competitive spike-timing dependent plasticity in the connections from the chains to the readout network.

TL;DR: The degeneration of the cerebellum associated with spinocerebellar types 6 and 8 appears to lead to quantitative rather than qualitative deficits in temporal processing, and the lack of any areas with greater activity in the spinocephalic group than in controls suggests that limited functional reorganization occurs in this condition.

Language within our grasp
TL;DR: It is proposed here that an observation/execution matching system provides a necessary bridge from'doing' to'communicating', as the link between actor and observer becomes a link between the sender and the receiver of each message.

Timing functions of the cerebellum
Richard B. Ivry,Steven W. Keele +1 more
TL;DR: 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.

Where and when to pay attention: the neural systems for directing attention to spatial locations and to time intervals as revealed by both PET and fMRI.
Jennifer T. Coull,Anna C. Nobre +1 more
TL;DR: Brain-imaging data revealed a partial overlap between neural systems involved in the performance of spatial versus temporal orientation of attention tasks, and hemispheric asymmetries revealed preferential right and left parietal activation for spatial and temporal attention, respectively.

TL;DR: 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.
