Summary
This review explores the evolution of sleep and wakefulness across species, detailing neurophysiological changes and brain interactions in vertebrates. It examines how metabolism and lifestyle influence sleep patterns in mammals.
Area of Science:
- Comparative neurobiology
- Evolutionary biology
- Sleep science
Context:
- Sleep and wakefulness are fundamental biological processes observed across diverse taxa.
- Understanding the evolutionary trajectory of sleep is crucial for comprehending its biological significance.
- Existing hypotheses on the evolution of sleep phases and stages in vertebrates require further empirical and theoretical examination.
Purpose:
- To provide a comprehensive overview of behavioral, somato-vegetative, and neurophysiological parameters of sleep and wakefulness.
- To critically evaluate current hypotheses regarding the evolutionary formation of sleep phases and stages in vertebrates.
- To present original experimental data on the neurophysiological development of sleep-wake characteristics in vertebrates, covering phylogeny and ontogeny.
Summary:
- The review synthesizes data on sleep-wake parameters in insects and vertebrates, correlating mammalian sleep characteristics with metabolic rate and lifestyle.

01:24Sleep-Wake Cycles
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

01:11Understanding Sleep
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

02:45Biological Clocks and Seasonal Responses
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
02:19Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...

01:22Stages of Sleep
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...
