According to D.T. Max sleep is defined as a dynamic state characterized by shifting levels of electrical activity and the flow of chemicals into various regions of the brain. A pinhead size cluster of cells called the ventrolateral preoptics nucleus (VLPO) send signals to arousal centres to stop producing histamine and other chemicals that keep us awake. Another cell cluster called the suprachiasmatic nucleus (SCN) generates the “wake-up” cue that signals the VLPO to stop activating the arousal system.
