For example, in the case of sleep research in an adult, with the help of the electroencephalogram, it was possible to identify that when the person felt sleepy, he had beta brain waves, this stage is shown when the person still has mental activities, they are characterized by being fast compared to the other brain waves. After this stage, the subject passes to the first phase of the sleep cycle, which is the alpha stage, in this phase the individual presents a state of decrease in their brain activities, these brain waves are characterized by being of greater extent and slower than the betas waves.
