TLDR
The results show that the information processing necessary for temporal judgements involves the parietal cortex, probably to optimise spatiotemporal accuracy in voluntary action.Abstract:
We investigated the involvement of the posterior parietal cortex in time perception by temporarily disrupting normal functioning in this region, in subjects making prospective judgements of time or pitch. Disruption of the right posterior parietal cortex significantly slowed reaction times when making time, but not pitch, judgements. Similar interference with the left parietal cortex and control stimulation over the vertex did not significantly change performance on either pitch or time tasks. The results show that the information processing necessary for temporal judgements involves the parietal cortex, probably to optimise spatiotemporal accuracy in voluntary action. The results are in agreement with a recent neuroimaging study and are discussed with regard to a psychological model of temporal processing and a recent proposal that time is part of a parietal cortex system for encoding magnitude information relevant for action.read more

Timing and time perception: A review of recent behavioral and neuroscience findings and theoretical directions
TL;DR: The present review article discusses the question of whether there is an internal clock (pacemaker counter or oscillator device) that is dedicated to temporal processing and reports the main hypotheses regarding the involvement of biological structures in time perception.
TUTORIAL REVIEW Timing and time perception: A review of recent behavioral and neuroscience findings and theoretical directions
TL;DR: A review of recent literature related to psychological time and time perception can be found in this article, where the roles of the cerebellum, of the cerebral cortices, and of the basal ganglia in the timing processes are emphasized.

The parietal cortex and the representation of time, space, number and other magnitudes
Domenica Bueti,Vincent Walsh +1 more
TL;DR: The contention that generalized magnitude processing is a more accurate conceptual description of how the brain deals with information about time, space, number and other dimensions is discussed.

Beyond the Number Domain
TL;DR: Evidence is discussed that the approximate number system (ANS) bears a set of behavioral and brain signatures that are universally displayed across animal species, human cultures and development, and whether the ANS constitutes a specialized cognitive and neural domain.

The 'when' pathway of the right parietal lobe.
Lorella Battelli,Alvaro Pascual-Leone,Alvaro Pascual-Leone,Patrick Cavanagh,Patrick Cavanagh +4 more
TL;DR: The results suggest that the right parietal lobe serves as part of a when pathway for both visual fields, and it is proposed that the disruption of this mechanism is the underlying cause of a wide range of seemingly unrelated tasks being impaired inright parietal patients.

Risk and safety of repetitive transcranial magnetic stimulation: report and suggested guidelines from the International Workshop on the Safety of Repetitive Transcranial Magnetic Stimulation, June 5–7, 1996
TL;DR: The guidelines for the use of rTMS cover the ethical issues, recommended limits on stimulation parameters, monitoring of subjects (both physiologically and neuropsychologically), expertise and function of the rT MS team, medical and psychosocial management of induced seizures, and contra-indications to r TMS.

TL;DR: Spread of excitation, which may be a warning sign for seizures, occurred in one subject and was not accompanied by increased MEP amplitude, suggesting that spread ofexcitation and amplitude changes are different phenomena and also indicating the need for adequate monitoring even with stimulations at low frequencies.

A theory of magnitude: common cortical metrics of time space and quantity
TL;DR: This work proposes here that time, space and quantity are part of a generalized magnitude system and outlines A Theory Of Magnitude (ATOM) as a conceptually new framework within which to re-interpret the cortical processing of these elements of the environment.
