Attention modulates our subjective perception of time. The less we attend to an event's duration, the shorter it seems to last. Attention to time or color stimulus attributes was modulated parametrically in an event-related functional magnetic resonance imaging study. Linear increases in task performance were accompanied by corresponding increases in brain activity. Increasing attention to time selectively increased activity in a corticostriatal network, including pre–supplementary motor area… 

The Attention Modulation on Timing: An Event-Related Potential Study

The present study parametrically varied the attention to the durations of a 1000-Hz pure tone and localized the cortical regions that were sensitive to the attention modulation on timing to provide temporal and spatial correlates of attention-modulated time processing.

The supplementary motor area in motor and perceptual time processing: fMRI studies

The involvement of the supplementary motor area (SMA) in the encoding of target durations by reporting convergent fMRI data from motor and perceptual timing tasks suggests that the SMA plays a key role in time processing as part of the striato-cortical pathway previously identified by animal studies, human neuropsychology and neuroimaging.

The Neuromagnetic Dynamics of Time Perception

Examining real-time cortical dynamics is crucial for understanding time perception. Using magnetoencephalography we studied auditory duration discrimination of short (<.5 s) versus long tones (>.5 s)

The physiological basis of attentional modulation in extrastriate visual areas

Baseline activity in motion- and color-sensitive areas of extrastriate cortex was enhanced by selective attention to these attributes, even without moving or colored stimuli, and visually evoked responses increased along with baseline activity, consistent with the hypothesis that attention modulates sensitivity of neuronal populations to inputs by changing background activity.

Activation of the supplementary motor area and of attentional networks during temporal processing

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.

The evolution of brain activation during temporal processing

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.

Processing of temporal information and the basal ganglia: new evidence from fMRI

Abstract. Temporal information processing is a fundamental brain function, which might include central timekeeping mechanisms independent of sensory modality. Psychopharmacological and patient

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

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.

The supplementary motor area in motor and sensory timing: evidence from slow brain potential changes

The data suggest that the SMA subserves important functions in timing both sensory and motor tasks, and proposes that it either provides the ”pulse accumulation” process commonly postulated in models of time processing or that it receives output from this process through striatal efferent pathways.

Interval and ordinal properties of sequences are associated with distinct premotor areas.

The findings suggest overlapping but different kinds of sequential representation, depending on both the ordinal and interval aspects as well as motor requirements, in the preSMA, SMA, MI and medial CE.

A PET study of visuospatial attention

PET findings indicate that parietal and frontal regions control different aspects of spatial selection, and the functional asymmetry in superior parietal cortex may be relevant for the pathophysiology of unilateral neglect.
