Are there differences in the types of dreams that occur at several(predicate) times & Describe how sleep changes during the course of one night - Essay ExamplePolysomnography light upons a 50% drop in activity between alertness and phase 1 sleep. The eyes are fill up during phase 1 sleep, but if woken up from it, then an individual might feel as if they hurt not slept yet. degree 1 might last between 5 to 10 transactions (Harris 23).Stage 2 is a time of light sleep where polysomnographic readings portray irregular peaks and valleys, or negative and unconditional waves (Harris 24). These waves show spontaneous phases of muscle tone joined with phases of muscle relaxation. Muscle tone of this type preempt be witnessed in other phases of sleep as a response to audio stimuli (Jung 53). The heart ambiguous slows, plus body temperature goes up. At this stage, the body gets ready to go into a lately sleep.These stages are deep sleep phases, with Stage 3 being less intense compared to Stage 4. These stages are referred to as delta or slow-wave sleep (Harris 24). In slow-wave sleep, particularly during Phase 4, the electromyogram records sluggish waves of high amplitude, showing a expression of rhythmic continuity and deep sleep (Harris 24 and Jung 54).The time of non-rapid eye movement sleep, abbreviated as NREM, comprises of phases 1 to 4 and lasts between 90 minutes to two hours, each phases lasting roughly five to 15 minutes (Harris 25). However, surprisingly enough, phase 2 and phase 3 reiterate backwards prior to attaining REM sleep. Thus, a blueprint sleep sequence has this pattern waking, stage 1 to 4, and then back to 2 via 3, REM. In essence, REM sleep takes place just 90 minutes following sleep onset (Harris 25).REM sleep is discernible from NREM sleep through transformations in physiological states, including its distinguishing fast eye movements (Harris 25). Nevertheless, polysomnograms reveal wave patterns in REM similar as the ones in phase 1 sleep (Jung 57). During normal sleep (in individuals missing disorders of wake-sleep patterns or REM behaviour disorder), respiration and heart rate accelerate and perform irregular, whereas the legs,
