During REM sleep, a person's eyes move back and forth rapidly. This may happen during a stroke, or when there is severe bleeding or swelling in the brain. Scientists in Finland have discovered a central core network brimming with the same activity regardless of whether a person goes to sleep normally or loses consciousness due to anesthesia. Sleep is regulated by two body systems: sleep/wake homeostasis and the circadian biological clock. During the night, these cycles of slow wave and REM sleep alternate, with the slow wave sleep becoming less deep and the REM periods more prolonged until waking occurs. The first sleep cycle is often the shortest, ranging from 70-100 minutes, while later cycles tend to fall between 90 and 120 minutes.

The circadian clock-- also known as the suprachiasmatic nucleus (SCN)-- is a cluster of thousands of cells found in the hypothalamus area of the brain. Absence of sleep can hinder the normal rhythm of appetite hormones. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, is a product of brain plasticity, the structural changes within synapses that create associations between stimuli. Lack of consciousness can happen during coma or brain death. People generally follow a “biological clock” that impacts when they naturally become drowsy, when they fall asleep, and the time they naturally awaken. You may have reflexive and involuntary reactions. Level of consciousness (LOC) is a measurement of a person's arousability and responsiveness to stimuli from the environment.
