“…Recently, there has been a renewed interest in studying this temporal aspect of our behavior and the way in which our brain encodes this information. This has resulted in several different types of models on duration encoding that each propose different mechanisms for the encoding of duration (Gibbon, 1977;Ivry & Schlerf, 2008;Jones & Boltz, 1989;Karmarkar & Buonomano, 2007;Matell & Meck, 2004;Van Wassenhove, 2009). …”

“…However, behavioral studies have shown that trial history effects and the duration after-effect do not show any selectivity to low-level visual features such as orientation (Li, Yuan, & Huang, 2015;Walker et al, 1981), arguing against a role of early visual cortex in channel based duration processing. Furthermore, many other different brain areas have been implicated in duration processing, providing alternative possible neural loci for the channel based encoding of duration (Hayashi et al, 2015;Ivry & Schlerf, 2008;Mauk & Buonomano, 2004). For example, single cell recordings in macaques have revealed duration selectivity in striatal neurons (Mello, Soares, & Paton, 2015) as well as in the pre-supplementary motor area (pre-SMA) (Merchant, Pérez, Zarco, & Gámez, 2013).…”

An investigation of the spatial selectivity of the duration after-effect

a b s t r a c tAdaptation to the duration of a visual stimulus causes the perceived duration of a subsequently presented stimulus with a slightly different duration to be skewed away from the adapted duration. This pattern of repulsion following adaptation is similar to that observed for other visual properties, such as orientation, and is considered evidence for the involvement of duration-selective mechanisms in duration encoding. Here, we investigated whether the encoding of duration -by duration-selective mechanisms -occurs early on in the visual processing hierarchy. To this end, we investigated the spatial specificity of the duration after-effect in two experiments. We measured the duration after-effect at adapter-test distances ranging between 0 and 15°of visual angle and for within-and between-hemifield presentations. We replicated the duration after-effect: the test stimulus was perceived to have a longer duration following adaptation to a shorter duration, and a shorter duration following adaptation to a longer duration. Importantly, this duration after-effect occurred at all measured distances, with no evidence for a decrease in the magnitude of the after-effect at larger distances or across hemifields. This shows that adaptation to duration does not result from adaptation occurring early on in the visual processing hierarchy. Instead, it seems likely that duration information is a high-level stimulus property that is encoded later on in the visual processing hierarchy.

“…While dedicated neural structures for time perception have been described (Buhusi and Meck, 2005;Coull et al, 2004;Harrington et al, 1998;Ivry and Schlerf, 2008;Morillon et al, 2009;Treisman et al, 1990;van Wassenhove, 2009;Wittmann, 2009Wittmann, , 2013, the encoding of sensory event timing has been proposed to result from the intrinsic dynamics of neural populations not necessarily dedicated to temporal processing (Johnston and Nishida, 2001;Karmarkar and Buonomano, 2007;van Wassenhove, 2009). For instance, the timing of a colored visual patch could be encoded in the dynamics of the neural population dedicated to the analysis of color (Karmarkar and Buonomano, 2007;Moutoussis and Zeki, 1997).…”

Encoding of event timing in the phase of neural oscillations

a b s t r a c t a r t i c l e i n f oTime perception is a critical component of conscious experience. To be in synchrony with the environment, the brain must deal not only with differences in the speed of light and sound but also with its computational and neural transmission delays. Here, we asked whether the brain could actively compensate for temporal delays by changing its processing time. Specifically, can changes in neural timing or in the phase of neural oscillation index perceived timing? For this, a lag-adaptation paradigm was used to manipulate participants' perceived audiovisual (AV) simultaneity of events while they were recorded with magnetoencephalography (MEG). Desynchronized AV stimuli were presented rhythmically to elicit a robust 1 Hz frequency-tagging of auditory and visual cortical responses. As participants' perception of AV simultaneity shifted, systematic changes in the phase of entrained neural oscillations were observed. This suggests that neural entrainment is not a passive response and that the entrained neural oscillation shifts in time. Crucially, our results indicate that shifts in neural timing in auditory cortices linearly map participants' perceived AV simultaneity. To our knowledge, these results provide the first mechanistic evidence for active neural compensation in the encoding of sensory event timing in support of the emergence of time awareness.

“…It is an ongoing debate whether the human time-keeping system might consist of a single pacemaker-accumulator mechanisms or whether multiple pacemakers and accumulators might exist that are used depending on the tasks at hand (see Grondin, 2010, for example). For different time scales, for example, such as milliseconds, seconds to hours, or circadian cycles, previous research suggests that several internal clocks exist that differ from each other in their timekeeping properties (see Buhusi & Meck, 2009;Ivry & Schlerf, 2008). Whether even more specialized time-keeping mechanisms such as modality specific mechanisms, for example, exist is still under debate (e.g., Gamache & Grondin, 2010;Ulrich, Nitschke, & Rammsayer, 2006).…”

Duration perception in crossmodally-defined intervals

How humans perform duration judgments with multisensory stimuli is an ongoing debate. Here, we investigated how sub-second duration judgments are achieved by asking participants to compare the duration of a continuous sound to the duration of an empty interval in which onset and offset were marked by signals of different modalities using all combinations of visual, auditory and tactile stimuli. The pattern of perceived durations across five stimulus durations (ranging from 100 ms to 900 ms) follows the Vierordt Law. Furthermore, intervals with a sound as onset (audio-visual, audio-tactile) are perceived longer than intervals with a sound as offset. No modality ordering effect is found for visualtactile intervals. To infer whether a single modality-independent or multiple modalitydependent time-keeping mechanisms exist we tested whether perceived duration follows a summative or a multiplicative distortion pattern by fitting a model to all modality combinations and durations. The results confirm that perceived duration depends on sensory latency (summative distortion). Instead, we did not find evidence for multiplicative distortions. The results of the model and the behavioural data support the concept of a single time-keeping mechanism that allows for judgments of durations marked by multisensory stimuli.
