When awake, most people exhibit brain wave, (EEG) patterns that can be classified into two types of waves, beta and alpha. Beta waves are those associated with day to day wakefulness. These waves are the highest in frequency and lowest in amplitude, and also more desynchronous than other waves.

What brain structure is most responsible for monitoring circadian rhythm?
The suprachiasmatic nucleus (SCN) of the mammalian hypothalamus has been referred to as the master circadian pacemaker that drives daily rhythms in behavior and physiology.
What part of the brain is most associated with arousal?
One area of the brain that promotes arousal is the tuberomammillary nucleus (TMN) .
What type of brain waves are present when we are awake quizlet?
A stage when a person is awake, EEG patterns exhibit two types of waves: beta and alpha .
What are the brain waves in order from fastest to slowest?
Namely, the Gamma, Beta, Alpha, Theta and Delta Waves arranged from fastest to slowest.
What is Stage 2 of sleep called?
Stage 2 non-REM sleep is a period of light sleep before you enter deeper sleep. Your heartbeat and breathing slow, and muscles relax even further. Your body temperature drops and eye movements stop. Brain wave activity slows but is marked by brief bursts of electrical activity.
Which state is marked by relatively low levels?
Sleep is a state marked by relatively low levels of physical activity and reduced sensory awareness that is distinct from periods of rest that occur during wakefulness.
How long does a complete sleep cycle last?
A full sleep cycle takes about 90 to 110 minutes . Your first REM period is short. As the night goes on, you'll have longer REM sleep and less deep sleep.
What is rapid eye sleep?
Rapid eye movement ( REM ) sleep behavior disorder is a sleep disorder in which you physically act out vivid, often unpleasant dreams with vocal sounds and sudden, often violent arm and leg movements during REM sleep — sometimes called dream-enacting behavior.
What is arousal state?
Affect arousal describes the state of feeling awake, activated, and highly reactive to stimuli . There are both psychological and physiological components to the state of arousal. Psychologically, the state of arousal is associated with the subjective experience of feelings including high energy and tension.
At what time of day is energetic arousal highest?
Thayer found that arousal varies with time of day, for many of us being highest around noon and lower in the morning and evening.
Is it normal to wake up during REM sleep?
Many don't know that people can wake up during REM sleep even though it is the deepest, most intense stage. Sometimes, people wake only for a short time and do not remember it in the morning. Other times, people remember longer wakening periods.
What is Stage 4 sleep called?
Electroencephalography. These four sleep stages are called non-rapid eye movement (non-REM) sleep, and its most prominent feature is the slow-wave (stage IV) sleep. It is most difficult to awaken people from slow-wave sleep; hence it is considered to be the deepest stage of sleep.
What happens in slow-wave sleep?
Slow-wave sleep (SWS) refers to phase 3 sleep, which is the deepest phase of non-rapid eye movement (NREM) sleep, and is characterized by delta waves (measured by EEG). Dreaming and sleepwalking can occur during SWS. SWS is thought to be important for memory consolidation.
What type of brain waves are present when awake?
Beta . Just below gamma waves on the spectrum are the beta waves. These waves fall into the 12-38 Hz range. These are the brain waves that dominate when you're awake, alert, and engaged.
