A rich tradition of normative psychophysics has identified two ubiquitous properties of interval timing: the scalar property, a strong form of weber’s law, and ratio comparison mechanisms. Finding the neural substrate of these properties is a major challenge for neurobiology.

Interval timing refers to the cognitive ability to remember and process the length of time between two events, primarily on the scale of hundreds of milliseconds to tens of seconds it is critical for a wide range of behaviors, and deficits in interval timing are correlated with several disorders, including schizophrenia, adhd, and autism.

This research topic on “interval timing and time-based decision making” emerged from a symposium sponsored by the european cost-action on time in mental activity: theoretical, behavioral, bioimaging, and clinical perspectives (timely) that was a satellite of the european brain and behaviour society meeting held in seville, spain (september 9, 2011). The focus of that timely symposium was on “neurobiology of time perception: from normality to dysfunction” and was organized by valérie.

The authors draw together and develop previous timing models for a broad range of conditioning phenomena to reveal their common conceptual foundations: first, conditioning depends on the learning of the temporal intervals between events and the reciprocals of these intervals, the rates of event occurrence. Second, remembered intervals and rates translate into observed behavior through decision.

Timing is extremely important for movement, and understanding the neurobiological basis of rhythm perception and reproduction can be helpful in addressing motor recovery after brain lesions. In this quest, the science of music might provide interesting hints for better understanding the brain timing mechanism.

Historically, the neural mechanisms of interval timing have been interpreted through internal clock analogies, that perhaps involve a circuit(s) with the dedicated purpose of timing.
This paper describes the current state of pacemaker-accumulator timing models, and how these models can be extended to include more detailed accounts of memory processes in interval timing, and at the same time be used as a basis for exploring the neurobiology of interval timing.

The discovery of timing signals in hippocampal neurons, including evidence of “time cells” and of gradual changes in ensemble activity over long timescales, strongly suggests that the hippocampus is important for this capacity. However, behavioral evidence that the hippocampus is critical for the memory of elapsed time is lacking.
Thus, neurobiology of interval timing will integrate for the first time the current knowledge of both animal behavior and human cognition of the passage of time in different behavioral context, including the perception and production of time intervals, as well as rhythmic activities, using different experimental and theoretical frameworks.
The study of how the brain processes temporal information is becoming one of the most important topics in systems, cellular, computational, and cognitive neuroscience, as well as in the physiological bases of music and language. During the last and current decade, interval timing has been intensively studied in humans and animals using increasingly sophisticated methodological approaches.

Introduction to the neurobiology of interval timing hugo merchant and victor de lafuente abstract time is a fundamental variable that organisms must quantify in order to survive. In humans, for example, the gradual development of the sense of duration and rhythm is an essential skill in many facets of social behavior.
Interval timing, which operates on timescales of seconds to minutes, is distributed across multiple brain regions and may use distinct circuit mechanisms as compared to millisecond timing and circadian rhythms. However, its study has proven difficult, as timing on this scale is deeply entangled with other behaviors. Several circuit and cellular mechanisms could generate sequential or ramping.

The entorhinal-hippocampal circuit can encode features of elapsed time, but nearly all previous research focused on neural encoding of “implicit time. Recent research has revealed encoding of “explicit time” in the medial entorhinal cortex (mec) as mice are actively engaged in an interval timing task.
Because timing behavior follows the scalar timing property (2, 3), this variability will be proportionally greater for longer intervals. When a peth is averaged across trials, the variability in the sound-to-light interval will influence the peth in a scaled fashion: a more variable interval corresponds to a gentler slope.
