Neural correlates of human time perception

Abstract

In order to coherently perceive and effectively interact with the world around us, we must integrate sensory signals from various modalities (e.g., audition and vision). One of the key factors determining whether sensory signals are integrated is their relative timing. Despite over a century of study, it remains unclear what processes underlie our brain's capacity to extract and evaluate the timing of, and between, sensory signals. Many proposals have been made regarding the computational processes that might be implemented by the brain to facilitate timing perception.

Neural-latency noise places limits on human sensitivity to the timing of events

“…Hence, while our inference is less robust than if we had independently verified the hypothesis in three separate data sets, we consider the degree of protection against false positives to be reasonable. We note, however, that a pilot for this project, with only AV stimuli and a less fully developed analysis, failed to detect the correlations we report here (Keane, 2019). As such, our findings would certainly bear replication.…”
