“…Moreover, this difference was more prominent at frontal and central electrode sites between 500 and 1500 ms after the offset of S1. The spatial distribution of these slow waves was similar to that reported in other ERP/EEG studies of duration information processing (e.g., Monfort, et al, 2000;Monfort & Pouthas, 2003;Schubotz & Friederici, 1997) and the polarity and the magnitude of the amplitude difference were comparable to those reported by Monfort and Pouthas (2003) in their Gap trial modification of the standard S1-S2 paradigm.…”

Whether duration magnitude modulates the cognitive resources required to represent that duration in memory is a fundamental question about the cognitive architecture of interval timing. The amplitudes of the Event-Related Potential (ERP) Slow Waves (SWs) elicited when participants maintain representations of different durations (e.g., 1500 versus 3000 ms) in memory may provide an answer to this question because increased positive SWs have been associated with increased working memory demands in studies of verbal and spatial memory. Here, participants judged whether a probe stimulus (S2) was the same duration as the preceding sample stimulus (S1). SWs recorded during a 2 s delay interval between S1 and S2 presentation were significantly more positive in the 3000 ms condition than in the 1500 ms condition, particularly at frontal-central electrode locations. This result suggests that the magnitude of the duration to be remembered influences the cognitive resources required to represent that duration in working memory.

“…Most EEG time perception studies have focused on the evoked responses (ERPs) which indicate how long it takes various regions of the brain to process presented stimuli. One important use of this technique has been to show evoked neural activity during time perception tasks in healthy adults, such as duration discrimination (Lange et al, 2003;Monfort et al, 2000;Naatanen et al, 2004;Schubotz and Friederici, 1997), time-interval reproduction (Monfort and Pouthas, 2003), and manipulating attentional processes requiring temporal processing (Griffin et al, 2002).…”

“…Several neuroimaging studies utilizing functional Magnetic Resonance Imaging (fMRI), Positron Emission Tomography (PET), or Event-Related Potential (ERP) have suggested a preferential involvement of the right frontal cortex (Brunia et al 2000;Maquet et al 1996;Lewis & Miall, 2006b) while other studies suggest the involvement of the left frontal cortex (Jech et al 2005;Hinton & Meck, 2004;Kawashima et al 2000;Rubia et al 1998;Harrington et al 2004). Still other accounts suggest that both hemispheres are necessary for accurate temporal processing (Monfort, Pouthas & Ragot 2000;Livesey, et al 2007;Coull et al 2000;Macar et al 2002;Schubotz et al 2000;Rao et al 2001).…”

Previous research suggests that the frontal lobes are essential for temporal processing. We report a patient, MN, with probable Frontotemporal Dementia (FTD) who was tested on a battery of timing tasks with stimuli in the sub-and supra-second range. MN demonstrated a substantial over-estimation and under-production of target intervals on estimation and production tasks respectively but was as accurate as controls on a reproduction task. Furthermore, this deficit was markedly different for auditory and visual stimuli on production and estimation tasks; estimates of the duration of auditory stimuli were 3-4 times longer than for comparable visual stimuli. She performed normally on a task requiring her to judge whether a stimulus was longer or shorter than a standard duration with both sub-and supra-second stimuli. She performed well on control tasks involving estimation, production and reproduction of line lengths suggesting that her deficits were not attributable to a generalized cognitive impairment or an inability to make magnitude judgments. These data suggest that bifrontal pathology disrupts the "clock" or memory for time.
