(a) There are psycho physiological measures of sleep that are based on electroencephalogram ( EEG) waves that accompany sleep consisting of high and low voltages. Thus, there are periods throughout the night that are dominated by voltages or fast waves. These waves or rapid eye movements (REM) occur during closed eyelids of sleeping under the low voltage activity (Pinel, 2006). According to Pinel, there are four stages of sleep: (a) Stage 1 in which the EEG waves are a low-voltage, high frequency signal, (b) stage 2 increases in EEG frequency and higher amplitude and lower frequency, (c) EEG is defined by the largest and slowest EEG waves (delta waves), and (d) Stage 4 consists of predominant delta waves. After the person reaches stage 4, the individual reverts to stage 1] (p. 343). In addition, according to Pinel, there are certain periods during the sleep period when there are periods of wakefulness; however, individuals don't remember being awake.
