Brain Waves Explained

As the brain transitions from wakefulness to sleep, its electrical activity shifts dramatically. While awake, brain waves are frenetic and desynchronized, akin to a chaotic crowd in a stadium. However, as one begins to fall asleep, the back of the brain, particularly the occipital cortex, starts to settle into a calmer alpha rhythm, marking the onset of relaxation. This fascinating process reveals how different brain regions communicate at various frequencies, ultimately influencing our sleep experience.
