As mentioned earlier, REM sleep is marked by rapid movements of the eyes. It is administered alone or in conjunction with doses of melatonin (the hormone secreted by the pineal gland). Individuals who do rotating shift work are also likely to experience disruptions in circadian cycles. d. the gender gap between male and female life expectancy has increased. For example, the National Institutes of Drug Abuse has sponsored research that suggests the misuse and abuse of the prescription pain killers hydrocodone and oxycodone are significant public health concerns (Maxwell, 2006). Unlike the other sleep disorders described in this section, a person withnarcolepsycannot resist falling asleep at inopportune times. Awareness of external stimuli includes experiences such as seeing the light from the sun, feeling the warmth of a room, and hearing the voice of a friend. The effects of all psychoactive drugs occur through their interactions with our endogenous neurotransmitter systems. Some sleep-deprived individuals have difficulty staying awake when they stop moving (for example sitting and watching television or driving a car). In contrast, a person who haspsychological dependencehas an emotional, rather than physical, need for the drug and may use the drug to relieve psychological distress. Caffeine is another stimulant drug. The pons is important for regulating rapid eye movement (REM) sleep (National Institutes of Health, n.d.). These episodes can last 1020 seconds or longer and often are associated with brief periods of arousal. b. life expectancy has reached a new high. For example, withdrawal from sedative drugs often produces unpleasant arousal and agitation. If we have biological rhythms, then is there some sort ofbiological clock? Social programs like Medicare: a - offer health coverage for the older adults 24. In 2013, the U.S. Food and Drug Administration recommended tighter controls on their medical use. In other words, physical dependence in and of itself is of limited utility in determining whether or not someone has a substance use disorder. The heart rate slows .

Other drugs, including the opioid buprenorphine, have also been used to alleviate symptoms of opiate withdrawal. Unlike Freud and Jung, Cartwrights ideas about dreaming have found empirical support. Methamphetamine addiction produces an intense craving that is difficult to treat. Theta wavesare even lower frequency (47 Hz), higher amplitude brain waves than alpha waves. Narcolepsy is associated with reduced levels of the signaling molecule hypocretin in some areas of the brain (De la Herrn-Arita & Drucker-Coln, 2012; Han, 2012), and the traditional stimulant drugs do not have direct effects on this system. typically follow the example of their parents more than their friends.

Awareness of external stimuli includes experiences such as seeing the light from the sun, feeling the warmth of a room, and hearing the voice of a friend. As scary as it sounds, many sleep researchers believe that homicidal sleepwalking is possible in individuals suffering from the types of sleep disorders described below (Broughton et al., 1994; Cartwright, 2004; Mahowald, Schenck, & Cramer Bornemann, 2005; Pressman, 2007). Some of these approaches, such as using a bright light as shown inFigure 4.4, have been shown to alleviate some of the problems experienced by individuals suffering from jet lag or from the consequences of rotating shift work. Acetylcholine functions as a neurotransmitter in motor neurons. Sleep is characterized by certain patterns of activity of the brain that can be visualized using electroencephalography (EEG), and different phases of sleep can be differentiated using EEG as well. Lucid dreamsare dreams in which certain aspects of wakefulness are maintained during a dream state. In her case, the fact that her cataplexy was confined to the right side of her body was quite unusual. One of the most common treatments for sleep apnea involves the use of a special device during sleep. d. both b and c. 2. (b) Heroin is cooked on a spoon over a candle.

Individuals with insomnia often experience long delays between the times that they go to bed and actually fall asleep. These components include: These steps are conducive to being open to the heightened suggestibility of hypnosis. On January 16, 1997, Scott Falater sat down to dinner with his wife and children and told them about difficulties he was experiencing on a project at work. The suprachiasmatic nucleus (SCN) serves as the brains clock mechanism. Ahallucinogenis one of a class of drugs that results in profound alterations in sensory and perceptual experiences (Figure 4.18). This campaign is sponsored in part by the National Institute of Child Health and Human Development. In other words, dreaming involves constructing a virtual reality in our heads that we might use to help us during wakefulness. Parasomnias can occur in either REM or NREM phases of sleep. Amphetamines have a mechanism of action quite similar to cocaine in that they block the reuptake of dopamine in addition to stimulating its release (Figure 4.16). For example, Hobson (2009) suggests that dreaming may represent a state of protoconsciousness. Our sleep-wake cycle, which is linked to our environments natural light-dark cycle, is perhaps the most obvious example of a circadian rhythm, but we also have daily fluctuations in heart rate, blood pressure, blood sugar, and body temperature. Asleep spindleis a rapid burst of higher frequency brain waves that may be important for learning and memory (Fogel & Smith, 2011; Poe, Walsh, & Bjorness, 2010). Rather, the ISS r ecognizes mixed states and depressive symptoms during manic and hypomanic episodes. To date, people have used a variety ofnicotinereplacement therapies in addition to various psychotherapeutic options in an attempt to discontinue their use of tobacco products.

The Safe to Sleep campaign educates the public about how to minimize risk factors associated with SIDS. Research indicates that meditation may help reduce blood pressure, and the American Heart Association suggests that meditation might be used in conjunction with more traditional treatments as a way to manage hypertension, although there is not sufficient data for a recommendation to be made (Brook et al., 2013). Sleep apneais defined by episodes during which a sleepers breathing stops. (a) Delta waves, which are low frequency and high amplitude, characterize (b) slow-wave stage 3 and stage 4 sleep. We might even describe consciousness as a continuum that ranges from full awareness to a deep sleep. Try going to bed and waking up at the same time every day to keep your biological clock in sync so your body gets in the habit of sleeping every night. Sleepwalking, restless leg syndrome, and night terrors are all examples of parasomnias (Mahowald & Schenck, 2000). It is also common for these types of drugs to cause hallucinations of body sensations (e.g., feeling as if you are a giant) and a skewed perception of the passage of time. Mescaline and LSD are serotonin agonists, and PCP (angel dust) and ketamine (an animal anesthetic) act as antagonists of the NMDA glutamate receptor. Often, however, people wishing to learn to meditate receive some training in techniques to achieve a meditative state. In fact, ameta-analysis, which is a study that combines the results of many related studies, conducted within the last decade indicates that by the time we are 65 years old, we average fewer than 7 hours of sleep per day (Ohayon, Carskadon, Guilleminault, & Vitiello, 2004). Narcoleptic episodes take on other features of REM sleep. Site has information/education resources on a broad range of topics, including asthma, birth defects, radiation, sanitation, lead in blood, and more. Therefore, no movement of voluntary muscles occurs during REM sleep in a normal individual; REM sleep is often referred to as paradoxical sleep because of this combination of high brain activity and lack of muscle tone. Sleep debt and sleep deprivation have significant negative psychological and physiological consequencesFigure 4.5. These effects can occur as a function of accumulated sleep debt or in response to more acute periods of sleep deprivation. Why do we devote so much time to sleeping? This pattern of temperature fluctuation, which repeats every day, is one example of a circadian rhythm. Sleep reboundrefers to the fact that a sleep-deprived individual will fall asleep more quickly during subsequent opportunities for sleep. Taking a different approach to explain hypnosis, the social-cognitive theory of hypnosis sees people in hypnotic states as performing the social role of a hypnotized person. Several of the nurses interviewed commented that their work schedules affected their relationships with their family.

Some view a hypnotized persons behavior not as an altered or dissociated state of consciousness, but as their fulfillment of the social expectations for that role (Coe, 2009; Coe & Sarbin, 1966). This will be followed by brief descriptions of the effects of some of the more well-known drugs commonly used today. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. a. .
