“…Compatible with these results, we provided evidence for the functional dissociation of temporal duration and spatial location working memory in intact young adults using a selective interference paradigm (H€ a albig, Mecklinger, Schriefers, & Friederici, 1998). Lesion studies support the notion that the frontal cortex is involved in duration processing (Casini & Ivry, 1999;Mangels et al, 1998;Nichelli et al, 1995). Using a bisection procedure, Nichelli et al (1995) found impaired accuracy on duration discrimination in the millisecond range (100-900 ms) and for longer intervals (8-32 s), but normal performance on a line-length discrimination task.…”

“…Electrophysiological, neuropharmacological, and lesion data, as well as imaging studies, have indicated that the neural correlate mediating duration processing consists of a network of distributed neural systems, involving cerebellum (Casini & Ivry, 1999;Ivry & Keele, 1989;Jueptner et al, 1995;Nichelli, Alway, & Grafman, 1996), basal ganglia (Gibbon, Malapani, Dale, Corby, & Gallistel, 1997;Hinton, Meck, & MacFall, 1996;Meck, 1996;Pastor, Artieda, Jahanshahi, & Obeso, 1992;Rammsayer, 1994;Rammsayer & Lima, 1990), parietal (Cabeza et al, 1997;Coull & Nobre, 1998), and prefrontal cortex (Casini & Ivry, 1999;Gibbon et al, 1997;Hinton et al, 1996;Nichelli, Clark, Hollnagel, & Grafman, 1995). Yet, for each of these structures there is little agreement on their functional contribution to duration processing and on their involvement in the processing of different time ranges (Gibbon et al, 1997;Ivry, 1996;Ivry & Keele, 1989;Jueptner et al, 1995;Meck, 1996;Nichelli et al, 1995;Rammsayer, 1994).…”

“…Concerning the processing of duration information, recent electrophysiological (Casini & Macar, 1996;Elbert, Ulrich, Rockstroh, & Lutzenberger, 1991;Schubotz & Friederici, 1997) and lesions studies (Casini & Ivry, 1999;Mangels et al, 1998;Nichelli et al, 1995) have also emphasized the involvement of frontal brain structures. For example, in a study using event-related brain potentials (ERP), differently distributed ERPs were reported for temporal duration and spatial location working memory tasks with stimulus durations in the millisecond range (275, 300, 570, 650 ms).…”

“…Considering duration as a stimulus dimension (equivalent to shape and location), one could be tempted to suppose domain-specific neural assemblies contributing to duration processing. However, even if there is considerable evidence that memory for temporal duration depends on the integrity of the frontal lobes (Casini & Ivry, 1999;Casini & Macar, 1996;Elbert et al, 1991;Mangels et al, 1998;Nichelli et al, 1995;Schubotz & Friederici, 1997), variability of lesion size and location in the cited neuropsychological studies do not allow to identify any specific area within the frontal cortex that is involved necessarily in the processing of temporal duration information.…”

“…(Baddeley, 1986;Fuster, 1989;Smith et al, 1995). Given the involvement of the frontal lobes in executive monitoring functions, several authors propose that deficits in temporal memory might be secondary to executive dysfunctions (Casini & Ivry, 1999;Mangels, 1997;Mangels et al, 1998;Shimamura et al, 1990;Tracey, Faro, Mohamed, Pinsk, & Pinus, 2000).…”

This study aimed to test the hypothesis that impairments of temporal duration processing after frontal lobe lesions reflect deficits in executive monitoring functions rather than a domain-specific deficit in the maintenance of duration information in working memory. Patients with frontodorsal lesions, clinical controls with post-central lesions, and healthy controls performed recognition and classification tasks, which should allow for testing maintenance and monitoring functions, respectively. Results showed mild non-selective impairments of the frontal patients on both temporal and spatial recognition tasks, but a marked selective degradation on temporal classification while performance on spatial classification was unimpaired. This suggests that maintenance of duration information in working memory after frontal lesions is basically preserved but that, depending on executive task characteristics, there is a specific deficit in the strategic organization of this type of information.

ERPs and PET analysis of time perception: Spatial and temporal brain mapping during visual discrimination tasks

et al. 2000

View full text Add to dashboard Cite

ERPs were recorded from 12 subjects performing duration and intensity visual discrimination tasks which have been previously used in a PET study. PET data showed that the same network was activated in both tasks [P. Maquet et al., NeuroImage 3:119-126, 1996]. Different ERP waveforms were observed for the late latency components depending on the dimension of the stimulus to be processed: frontal negativity (CNV) for the duration task and parieto-occipital positivity (P300) for the intensity task. Using BESA software, the sources were first modelled with a "PET dipolar model" (right prefrontal, right parietal, anterior cingulate, left and right fusiforms). To obtain a better fit for ERPs recorded in each task, two sources (cuneus, left prefrontal area) had to be added. Consistently with PET findings, dipole modelling indicates that duration and intensity dimensions of a visual stimulus are processed in the same areas. However, ERPs also reveal prominent differences between the time course of the dipole activations for each task, particularly for sources contributing to the late latency ERP components. In the intensity task, dipoles located in the cuneus, the anterior cingulate, and the left prefrontal area yield largest activity within the P300 interval, then activity diminishes rapidly as the stimulus ends, whereas in the duration task, the cuneus and anterior cingulate are still active several hundred milliseconds following stimulus offset. Moreover, in the duration task, the activity of the right frontal dipole parallels the CNV waveform, whereas in the intensity task, this dipole is largely inactive. We assume that the right frontal area plays a specific role in the formation of temporal judgments.

Increases in brain activity during social competition predict decreases in working memory performance and later recall

In our fMRI experiment, participants completed a learning task in both a noncompetitive and a socially competitive learning environment. Despite reporting a preference for completing the task while competing, participants remembered significantly more during the task and later recalled more from the noncompetitive learning environment. Furthermore, during working memory maintenance, there was performance-related deactivation in the medial prefrontal cortex (mPFC) and the precuneus/PCC. During feedback presentation, there was greater activation in the mPFC and the precuneus/PCC while competing. Differential activation in the precuneus/PCC predicted worse later recall for information learned competitively. Since previous research suggests that the mPFC is involved in social-referencing, while the precuneus/PCC is implicated in off-task thoughts, our results suggest that receiving feedback regarding competition produces more activation in brain regions implicated in social interaction, as well as task distraction. While competition may make a task more enjoyable, the goal of winning may distract from maximizing performance. Hum Brain Mapp 38:457-471, 2017. © 2016 Wiley Periodicals, Inc.
