“…This amplitude is independent of the duration of the interval, because the CNV adjusts its slope to the duration of the interval after repeated exposure. These results resemble findings reported by Pfeuty et al (2005) in an explicit timing task showing that CNV activity peaks at the end of a memorized duration, and that its slope varies inversely with the length of this duration.…”

“…This amplitude was independent of interval duration because of adjustment of the slope of the CNV. Similar findings were reported by Pfeuty et al (2005) in a task where subjects compared a test duration against a memorized standard. One could interpret the development of the same amplitude negative shift in short and long SOA conditions as merely reflecting the buildup of a nonspecific state of motor readiness.…”

“…In explicit timing, effects on the CNV have been attributed to the medial premotor cortex or supplementary motor area (SMA) (Macar et al, 1999;Pfeuty et al, 2005). Activation of the SMA in timing tasks is thought to emerge from striatofrontal circuits involved in timing, a hypothesis supported by neuroimaging results (Macar et al, 2002;Ferrandez et al, 2003;Coull et al, 2004).…”

“…More strikingly, the CNV that develops during the presentation of a stimulus continues to rise for the duration of a memorized standard, but demonstrates a change in slope when that duration has elapsed and the current stimulus continues (Macar and Vidal, 2003;Pfeuty et al, 2003). Moreover, not only does the CNV peak at the end of a memorized duration, its slope is adjusted such that the CNV peak amplitude at extinction of a memorized standard is the same for short and long standards (Pfeuty et al, 2005). As proposed by Pfeuty et al (2005), these characteristics of the CNV are in accordance with a neural representation of time intervals by means of "climbing neuronal activity" (Durstewitz, 2003;Reutimann et al, 2004).…”

Neural representations of time for the judgment of temporal durations are reflected in electroencephalographic (EEG) slow brain potentials, as established in time production and perception tasks. Here, we investigated whether anticipatory processes in reaction-time procedures are governed by similar mechanisms of interval timing. We used a choice reaction task with two different, temporally regular stimulus presentation regimes, both with occasional deviant interstimulus intervals. Temporal preparation was shown in the form of adjustments in time course of slow brain potentials, such that they reached their maximum amplitude just before a new trial, independent of the duration of the interstimulus interval. Preparation was focused on a brief time window, demonstrated by a drop in amplitude of slow potentials as the standard interval had elapsed in deviant interstimulus intervals. Implicit timing influencing perceptual processing was shown in reduced visual-evoked responses to delayed stimuli after a deviant interstimulus interval and in a reduction of EEG ␣ power over the visual cortex at the time when the standard interval had elapsed. In contrast to explicit timing tasks, the slow brain potential manifestations of implicit timing originated in the lateral instead of the medial premotor cortex. Together, the results show that temporal regularities set up a narrow time window of motor and sensory attention, demonstrating the operation of interval timing in reaction time performance. The divergence in slow brain potential distribution between implicit and explicit timing tasks suggests that interval timing for different behaviors relies on qualitatively similar mechanisms implemented in distinct cortical substrates.

This chapter reviews recent human and nonhuman animal studies investigating neural signatures of time estimation. Investigation of the neural correlates of time estimation as measured by electrophysiology, electroencephalography, magnetoencephalography, and functional magnetic resonance imaging (fMRI) in humans and other animals has largely been focused on the to‐be‐timed period. Climbing neural activity (e.g., ramping) originating from the supplementary motor area has been implicated as a primary neural marker that coincides with the development of subjective experience of duration. However, it has recently been questioned whether such climbing neural activity directly reflects the neural mechanism(s) underpinning the sense of time. Given that the neural signatures recorded during the to‐be‐timed period are insufficient to explain various aspects of interval timing, this has led to the consideration of processes influencing timing before and after the to‐be‐timed period. Because many of these signatures are linked with the supplementary motor area, an extended discussion of the role of this cortical structure in timing and time perception is provided. These neural correlates are interpreted in light of contemporary theories of interval timing, such as the striatal beat frequency model. Future directions for the investigation of the functional and neural mechanisms of interval timing are also discussed.

Humans, and other animals, are able to easily learn the durations of events and the temporal relationships among them in spite of the absence of a dedicated sensory organ for time. This chapter summarizes the investigation of timing and time perception using scalp-recorded electroencephalography (EEG), a non-invasive technique that measures brain electrical potentials on a millisecond time scale. Over the past several decades, much has been learned about interval timing through the examination of the characteristic features of averaged EEG signals (i.e., event-related potentials, ERPs) elicited in timing paradigms. For example, the mismatch negativity (MMN) and omission potential (OP) have been used to study implicit and explicit timing, respectively, the P300 has been used to investigate temporal memory updating, and the contingent negative variation (CNV) has been used as an index of temporal decision making. In sum, EEG measures provide biomarkers of temporal processing that allow researchers to probe the cognitive and neural substrates underlying time perception.
