“…The role of sensory areas in temporal processing is a very recent finding (Bueti et al, 2008b) and indeed is the subject of some debate (Walsh, 2003;Ivry and Schlerf, 2008). Transient disruption of V5/MT can affect temporal discrimination of visual durations (Bueti et al, 2008a), providing some converging evidence for a role of visual cortex in temporal processing. The present findings now demonstrate the existence of a temporal signal much earlier in the visual pathway and in the primary visual cortex and show that this modulation here is retinotopic specific.…”

Anticipating the timing of future events is a necessary precursor to preparing actions and allocating resources to sensory processing. This requires elapsed time to be represented in the brain and used to predict the temporal probability of upcoming events. While neuropsychological, imaging, magnetic stimulation studies, and single-unit recordings implicate the role of higher parietal and motor-related areas in temporal estimation, the role of earlier, purely sensory structures remains more controversial. Here we demonstrate that the temporal probability of expected visual events is encoded not by a single area but by a wide network that importantly includes neuronal populations at the very earliest cortical stages of visual processing. Moreover, we show that activity in those areas changes dynamically in a manner that closely accords with temporal expectations.

“…Rather less attention has been paid to structures earlier in the visual pathway (Bueti et al, 2008a). It has been suggested, on theoretical grounds, that primary and extrastriate visual cortex may play a key role in encoding temporal variables.…”

“…More specifically, rTMS studies have shown that the right posterior parietal cortex has a critical role for timing intervals ( 1 sec) marked by either auditory or visual signals (Bueti, Bahrami, & Walsh, 2008), and for timing longer intervals (Koch, Oliveri, Torriero, & Caltagirone, 2003). In addition, using f MRI has revealed that the parietal cortex, which acts as an interface between sensory and motor processes, is involved in translating temporal information into action .…”

Suppose someone had to prepare a review article on visual perception, instead of time perception. This individual would probably ask for a series of reviews, with at least one-and probably several-dedicated to color, distance, shape, and motion perception, and maybe to other aspects of visual perception. It would be very difficult to complete the same exercise for time perception since the categories of temporal experiences are not as clearly defined. However, for a reader to understand the scope of a text on time perception, it is essential to develop a representation of what the main research avenues or categories are. The present text should help the reader to grasp the scope of recent literature related to psychological time and time perception.After a brief overview of the various perspectives on what could be meant by psychological time, the review will propose to identify of series of key concepts and empirical findings that should delineate the field of time perception and timing, and will discuss some models of time perception. The article also provides a review of the main recent findings in the field in which a neuroscientific approach to timing is adopted. In this section, the roles of the cerebellum, of the cerebral cortices, and of the basal ganglia in the timing processes are emphasized. Time Perception Beyond the Focus of the Present ReviewThere is a wide range of research on psychological time and temporal processing, mainly because of the ubiquity of time in behavior and the relevance of a temporal perspective in regard to living organisms and events. There is a vast literature in social psychology as to how behavior is shaped by time (see Perret-Clermont, 2005, or Strathman & Joireman, 2005, which includes topics such as time management, time perspective, and time orientation, or the relative value of past and future (Caruso, Gilbert, & Wilson, 2008;Zimbardo & Boyd, 1999). Even within the scope of experimental psychology, some studies have emphasized how the temporal structure of events determines our perception of the world (see the second part of Helfrich, 2003).Some authors who are interested in consciousness have adopted a phenomenological perspective on time (see the first part of Buccheri, Saniga, & Stuckey, 2003). Indeed, time and consciousness have become more closely linked recently with the development of a new area of research on the concept of chronesthesia (awareness of subjective time; Tulving, 2002), as opposed to noetic consciousness (awareness of the world) or autonoetic consciousness (awareness of self in time). Interestingly, there is now evidence that even animals can anticipate the future (Roberts, 2008).There are many psychological time studies related in various ways to memory processes (Block & Zakay, 2008). One research avenue deals with the chronology of events in our lives, particularly the memory of the order of occurrence of these events (Damasio, 2002;Friedman, 1993 The aim of the present review article is to guide the reader through portions of the human time per...

“…Over the past decade, a number of different brain areas have been implicated as key parts of a neural time-keeping mechanism, notably (among many others), event timing in the cerebellum [22], generalized magnitude processing for time, space and number in the right posterior parietal cortex [23,24], working memory related integration in the right prefrontal cortex [25,26], a right frontoparietal network [27], coincidence detection mechanisms using oscillatory signals in fronto-striatal circuits [28], hippocampal time-cells focused on the relation of time and distance [29], as well as integration of ascending interoceptive (that is, body) signals in the insular cortex [30,31]. The participation of many brain areas in the processing of temporal information attest the key role of time in a broad range of cognitive capacities.…”

Abstract. Contemporary research endeavors aim at equipping autonomous robots with human-like cognitive skills, in an attempt to promote robotic intelligence and make artificial agents more natural and more human-friendly. However, despite the crucial role that sense of time has in our daily activities, the capacity of artificial agents to experience the flow of time remains largely unexplored. The inability of existing systems to perceive time acts as an obstacle in implementing conscious artificial agents that put their experiences on the past-present-future timeline and develop durable symbiotic relationships with humans. The present paper elaborates on time-cognition coupling suggesting that the equipment of artificial agents with human-like time perception and time processing capacities is a prerequisite for bringing robotic cognition close to human intelligence.
