During sleep, the medulla oblongata controls sleep and arousal monitoring sensors to the cortex and other parts of the body. There are cholinergic neurons in the medulla oblongata that remain active during REM sleep. When a person experiences sleep walking, these neurons become inactive which causes a person to sleep while in action.
Breathing for respiration, palpitation of heart for blood circulation, digestion by elementary canal and essential neurological activities are some of the autonomous jobs our body is doing when we are at sleep. Our sub-conscious brain also remain awake during this phase. Some work to store memory in the brain is also done when we are at sleep.
Taking normal sleep every night help in consolidation of memory. During sleep the neuron cells do the needful to consolidate memory.
Yes. Sleep is essential to good brain and memory function.
The activation-synthesis theory provides a physiological explanation for the phenomenon of dreaming. It posits that dreams result from the brain's attempt to make sense of random neural activity that occurs during REM sleep. This random activation stimulates various parts of the brain, leading to the synthesis of a narrative or storyline as the mind attempts to interpret these signals. Ultimately, the theory suggests that dreams are a byproduct of the brain's intrinsic processes rather than meaningful reflections of our thoughts or experiences.

The frequency of your brain waves during REM sleep are beta (which incidentally occurs during the waking state as well). These are low voltage, high frequency waves.

During sleep, different brain waves are produced depending on the sleep stage. For example, during REM (rapid eye movement) sleep, the brain exhibits beta and theta waves, while in non-REM sleep stages, delta waves are prominent. Delta waves are associated with deep sleep and are typically seen in stages 3 and 4 of non-REM sleep.

The rhythmic bursts of brain activity that occur during Stage 2 sleep are called sleep spindles. These are short bursts of brain waves that help in the consolidation of memories and are characteristic of this stage of sleep.
During sleep, brain cells perform important functions such as consolidating memories, clearing out toxins, and restoring energy levels.
