TLDR
The dopaminergic system has great participation in impact on time perception and neurobiological basis of the executive functions and neurological diseases on the time perception is concluded.Abstract:
Dopaminergic system plays a key role in perception, which is an important executive function of the brain. Modulation in dopaminergic system forms an important biochemical underpinning of neural mechanisms of time perception in a very wide range, from milliseconds to seconds to longer daily rhythms. Distinct types of temporal experience are poorly understood, and the relationship between processing of different intervals by the brain has received little attention. A comprehensive understanding of interval timing functions should be sought within a wider context of temporal processing, involving genetic aspects, pharmacological models, cognitive aspects, motor control and the neurological diseases with impaired dopaminergic system. Particularly, an unexplored question is whether the role of dopamine in interval timing can be integrated with the role of dopamine in non-interval timing temporal components. In this review, we explore a wider perspective of dopaminergic system, involving genetic polymorphisms, pharmacological models, executive functions and neurological diseases on the time perception. We conclude that the dopaminergic system has great participation in impact on time perception and neurobiological basis of the executive functions and neurological diseases.read more

TL;DR: The dissociation reported here supports the idea that timing can be differentiated according to whether it is explicitly or implicitly processed, and that PD participants are selectively impaired in the explicit processing of time.

TL;DR: It is demonstrated that the time cognitive processes are underlying to performance in cognitive tasks and that many are the brain areas and functions involved and the modulators in the time perception performance.

TL;DR: Time-estimation task improves ADHD cognitive symptoms, with a substantial increase in cortical areas activity related to attention and memory, suggesting its use as a tool for cognitive timing function management and non-invasive therapeutic aid in ADHD.

Dissecting the links between reward and loss, decision-making, and self-reported affect using a computational approach
TL;DR: In this article, the authors examined the relationship between reward and loss experience, affect, and decision-making in humans using a novel judgement bias task analysed with a novel computational model and found that individuals reported more positive affective valence during periods of the task when prediction errors and offered decision outcomes were more positive.

TL;DR: It is proposed that the brain represents time in a distributed manner and tells the time by detecting the coincidental activation of different neural populations.

Abnormal neural oscillations and synchrony in schizophrenia
TL;DR: Dysfunctional oscillations may arise owing to anomalies in the brain's rhythm-generating networks of GABA (γ-aminobutyric acid) interneurons and in cortico-cortical connections.

TL;DR: A potential fourth executive function is considered: selective attention to features of a stimulus to be stored in WM which leads to increased probability of activating the medial prefrontal cortex (BA 32) in storage tasks.

TL;DR: It is argued that various cognitive deficits are enduring features of the schizophrenia illness, that they are not state-related and are not specific to subtypes of the illness, and, more specifically, that working memory and attention are characteristically impaired in patients with schizophrenia, irrespective of their level of intelligence.
