Summary
AI-generated from the abstractThe ability to perceive the passage of time differs between wakefulness and sleep. During wakefulness, neural mechanisms support time perception and temporal order judgments. In REM sleep, awareness of time resembles wakefulness, while in NREM sleep it is markedly reduced or absent. The evolutionary significance of the sense of time and its role in cognitive functions are discussed.

Abstract
In this paper, the authors review experimental data on the ability to perceive the passage of time during wakefulness and sleep. The evolutionary significance of the sense of time and its role in cognitive functions is discussed. Recent findings on neural mechanisms underlying perception and estimation of time as well as temporal order judgments are described. Similarities and differences of the awareness of time in wakefulness, REM, and NREM sleep are analyzed.
