As with many things related to the brain there no one simple answer. If we talk about the hypothalamus, an area of the brain that controls and regulates many things related to emotion, there are neurons within this region which are excited when you’re asleep, which can help control when you should be asleep. These are regulated by hormones, most famous being melatonin. The exact mechanism is unknown.
