“…Many psychophysical observations have been made about such discrete phenomenal processes. For example, it was experimentally shown that there exists a certain minimal interstimulus interval for which two successive events are consistently perceived as simultaneous; one can think of them as occurring within a single discrete epoch [398][399][400]. This phenomenon is compatible with the idea of a discrete perceptual "frame" of ~100 ms or less within which stimuli would be grouped and subjectively interpreted as a single event.…”

Concepts of space and time are widely developed in physics. However, there is a considerable lack of biologically plausible theoretical frameworks that can demonstrate how space and time dimensions are implemented in the activity of the most complex life-system -the brain with a mind. Brain activity is organized both temporally and spatially, thus representing space-time in the brain. Critical analysis of recent research on the space-time organization of the brain's activity pointed to the existence of so-called operational space-time in the brain. This space-time is limited to the execution of brain operations of differing complexity. During each such brain operation a particular short-term spatio-temporal pattern of integrated activity of different brain areas emerges within related operational space-time. At the same time, to have a fully functional human brain one needs to have a subjective mental experience. Current research on the subjective mental experience offers detailed analysis of space-time organization of the mind. According to this research, subjective mental experience (subjective virtual world) has definitive spatial and temporal properties similar to many physical phenomena. Based on systematic review of the propositions and tenets of brain and mind space-time descriptions, our aim in this review essay is to explore the relations between the two. To be precise, we would like to discuss the hypothesis that via the brain operational space-time the mind subjective space-time is connected to otherwise distant physical space-time reality.Key words: spatial, temporal, consciousness, cognition, operation, architectonics, EEG, field, metastability, physics, coordinative dynamics, self-organization, cortex.

“…This was found even though the temporal resolution of the auditory system is higher than the temporal resolution of the visual system. The delay values of 100-200 ms are far above the threshold for auditory temporal order judgements of~20 ms (Hirsh, 1959;Hirsh and Sherrick, 1961; cited in Knoblich and Repp, 2009). We therefore suggest that this similarity reflects common, modality-independent or supramodal, mechanisms in agency for auditory and visual gait consequences.…”

Agency is an important aspect of bodily self-consciousness, allowing us to separate own movements from those induced by the environment and to distinguish own movements from those of other agents. Unsurprisingly, theoretical frameworks for agency such as central monitoring are closely tied to computational models of sensorimotor control. Until recently agency research has largely focussed on goal-directed movements of the upper limbs. In particular, the influence of performance-related sensory cues and the relevance of prediction signals for agency judgements have been studied through a variety of spatio-temporal mismatches between movement and the sensory consequences of movement. However, agents often perform a different type of movement; highly automated movements that involve the entire body such as walking, cycling, and swimming with potentially different agency mechanisms. Here, we review recent work about agency for full-body movements such as gait, highlighting the effects of performance-related visual and auditory cues on gait agency. Gait movements differ from upper limb actions. Gait is cyclic, more rarely immediately goal-directed, and is generally considered one of the most automatic and unconscious actions. We discuss such movement differences with respect to the functional mechanisms of full-body agency and body-part agency by linking these gait agency paradigms to computational models of motor control. This is followed by a selective review of gait control, locomotion, and models of motor control relying on prediction signals and underlining their relevance for full-body agency.

“…When two visual events are perceived, so are their order but with an additional trick: temporal delays approximating the TOT between two visual events lead to perceptual motion phenomena ranging from flickering to phi motion, beta motion and alternation percepts (Wertheimer 1912). When using transient stimuli, an average TOT of approximately 30 ms is often observed within and across auditory, visual and tactile sensory modalities (Hirsh & Sherrick 1961;Hirsh & Fraisse 1964). The similarity of TOT across sensory modalities for simple stimuli is surprising given the differences of neural latencies between audition (Celesia 1976;Lakatos et al 2005) and vision (Buchner et al 1997;Schroeder 1998;Zeki 2001).…”

How long did it take you to read this sentence? Chances are your response is a ball park estimate and its value depends on how fast you have scanned the text, how prepared you have been for this question, perhaps your mood or how much attention you have paid to these words. Time perception is here addressed in three sections. The first section summarizes theoretical difficulties in time perception research, specifically those pertaining to the representation of time and temporal processing. The second section reviews non-exhaustively temporal effects in multisensory perception. Sensory modalities interact in temporal judgement tasks, suggesting that (i) at some level of sensory analysis, the temporal properties across senses can be integrated in building a time percept and (ii) the representational format across senses is compatible for establishing such a percept. In the last section, a two-step analysis of temporal properties is sketched out. In the first step, it is proposed that temporal properties are automatically encoded at early stages of sensory analysis, thus providing the raw material for the building of a time percept; in the second step, time representations become available to perception through attentional gating of the raw temporal representations and via re-encoding into abstract representations.
