(credit a: modification of work by Todd Huffman), Psychedelic images like this are often associated with hallucinogenic compounds. Users often consume the drug every few hours across days-long binges called runs, in which the user forgoes food and sleep. Identifying Internal States of the Brain | Technology Networks Once she was able to limit her use to less than 12 ounces of soda a day, both her mental and physical health gradually improved. Because GABA has a quieting effect on the brain, GABA agonists also have a quieting effect; these types of drugs are often prescribed to treat both anxiety and insomnia. a.

High doses increase agitation, paranoia, can cause hallucinations. If people are deprived of REM sleep and then allowed to sleep without disturbance, they will spend more time in REM sleep in what would appear to be an effort to recoup the lost time in REM. Guilleminault et al. The pineal and pituitary glands secrete a number of hormones during sleep. It may seem counterintuitive that stimulant medications are prescribed to treat a disorder that involves hyperactivity, but the therapeutic effect comes from increases in neurotransmitter activity within certain areas of the brain associated with impulse control.

By analyzing dreams, Freud thought people could increase self-awareness and gain valuable insight to help them deal with the problems they faced in their lives. Natural opioids, calledopiates, are derivatives of opium, which is a naturally occurring compound found in the poppy plant. Historically, hypnosis has been viewed with some suspicion because of its portrayal in popular media and entertainment (Figure 4.20). These drugs promote increased levels of neural activity. Some sleep-deprived individuals have difficulty staying awake when they stop moving (for example sitting and watching television or driving a car). As a group, hallucinogens are incredibly varied in terms of the neurotransmitter systems they affect. Unlike Freud and Jung, Cartwrights ideas about dreaming have found empirical support. Repeated use of these stimulants can have significant adverse consequences. When we are very young, we spend up to 16 hours a day sleeping. a. will be healthier than children because they are exposed to fewer infectious diseases.b.

This shift in policy may be in response to the scientific communitys recommendations and/or reflect changing public opinion regarding marijuana. Infants younger than 12 months appear to be at the highest risk for SIDS, and boys have a greater risk than girls. While caffeine may have some indirect effects on dopamine neurotransmission, its primary mechanism of action involves antagonizing adenosine activity (Porkka-Heiskanen, 2011). One hypothesis from this perspective might argue that sleep is essential to restore resources that are expended during the day. As part of treatment, the sleeping environment is often modified to make it a safer place for those suffering from RBD (Zangini, Calandra-Buonaura, Grimaldi, & Cortelli, 2011). Many of these drugs act as agonists of the dopamine neurotransmitter system. When we do this, we often experience jet lag. Quiz 1.docx - PSY-352 Health Psychology Quiz 1 Complete the following The following morning, he awoke to barking dogs and unfamiliar voices from downstairs. According to the dissociation view, hypnosis is effectively a dissociated state of consciousness, much like our earlier example where you may drive to work, but you are only minimally aware of the process of driving because your attention is focused elsewhere. The smokable form reaches the brain very quickly to produce an intense euphoria that dissipates almost as fast as it arrives, prompting users to continuing taking the drug. Awareness of internal stimuli includes feeling pain, hunger, thirst, sleepiness, and being aware of our thoughts and emotions. Generally, treatment for night terrors is unnecessary unless there is some underlying medical or psychological condition that is contributing to the night terrors (Mayo Clinic, n.d.). Adenosine is a neurotransmitter that promotes sleep. In addition, these individuals may wake up several times during the night only to find that they have difficulty getting back to sleep. In individuals diagnosed with a substance use disorder, there is a compulsive pattern of drug use that is often associated with both physical and psychological dependence. In fact, this relationship is so robust that some view the presence of RBD as a potential aid in the diagnosis and treatment of a number of neurodegenerative diseases (Ferini-Strambi, 2011). More specifically, homeostasis is the body's tendency to monitor and maintain internal states, such as temperature and blood sugar, at fairly constant and stable levels. What Is Inflammation? Types, Causes, Symptoms, and Treatment Sleepwalking, restless leg syndrome, and night terrors are all examples of parasomnias (Mahowald & Schenck, 2000). Fever.

Sleep apnea is much more common in overweight people and is often associated with loud snoring. QUIZ 1 EXTRA STUDY .docx - QUIZ 1 STUDY GUIDE HELP PLUS If someone stays awake for 48 consecutive hours, they could start to hallucinate. The typical episode can last from a minute or two to half an hour. This becomes a self-perpetuating cycle because increased anxiety leads to increased arousal, and higher levels of arousal make the prospect of falling asleep even more unlikely. It is much more difficult to awaken someone from sleep during stage 3 than during earlier stages. One important regulator of sleep-wake cycles is the hormonemelatonin. While the possession and use of marijuana remain illegal in many states, it is now legal to possess limited quantities of marijuana for recreational use in eleven states: Alaska, California, Colorado, Illinois, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont, and Washington. Vaping as a means to deliver nicotine is becoming increasingly popular, especially among teens and young adults.

In Hilgards experiments, he induced participants into a state of hypnosis, and placed their arms into ice water. Large-scale public health campaigns by the National Institutes of Health and the National Institute of Drug Abuse have led to recent declines in the opioid crisis. Not surprisingly, insomnia treatment may take one of several different approaches. Stick to a sleep schedule, even on the weekends. Dreams and their associated meanings vary across different cultures and periods of time. Incentral sleep apnea, disruption in signals sent from the brain that regulate breathing cause periods of interrupted breathing (White, 2005). Upset stomach and vomiting. The freebase version of cocaine, known as crack, is a potent, smokable version of the drug. Peritonitis - Symptoms and causes - Mayo Clinic During periods of emotional arousal, the woman complained that she felt some weakness on the right side of her body. Complications. Often, we are not completely aware of our surroundings, even when we are fully awake. Comparative research indicates, however, that the relationship that exists between predatory risk and sleep is very complex and equivocal. The substantial amount of research on SIDS has led to a number of recommendations to parents to protect their children (Figure 4.14). This chapter will discuss states of consciousness with a particular emphasis on sleep. b. absence of signs of malfunctioning. 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. week 3 midterm 1.docx - Question 1 1 / 1 pts John has been The body maintains homeostasis for many factors in addition to temperature. Hypnosis has also been used to draw out information believed to be buried deeply in someones memory. While hypnosis may be useful in enhancing memory or a skill, such enhancements are very modest in nature (Raz, 2011). Obviously, regular narcoleptic episodes could interfere with the ability to perform ones job or complete schoolwork, and in some situations, narcolepsy can result in significant harm and injury (e.g., driving a car or operating machinery or other potentially dangerous equipment). These initiatives include increasing access to treatment and recovery services, increasing access to overdose-reversal drugs like Naloxone, and implementing better public health monitoring systems (NIDA, 2019). Wakefulnessis characterized by high levels of sensory awareness, thought, and behavior. Pain relief, euphoria, sleepiness. This is illustrated by McCartys (2010) case study of a 50-year-old woman who sought help for the excessive sleepiness during normal waking hours that she had experienced for several years. These sleep episodes are often associated withcataplexy, which is a lack of muscle tone or muscle weakness, and in some cases involves complete paralysis of the voluntary muscles. The FDAs 2013 recommendation for tighter controls on opiate prescriptions left many patients addicted to prescription drugs like OxyContin unable to obtain legitimate prescriptions. This can lead to people compulsively using stimulants such as cocaine and amphetamines, in part to try to reestablish the persons physical and psychological pre-use baseline.

Psychological dependence on these drugs is also possible. Codeineis an opioid with relatively low potency. Drugs in this category include cocaine, amphetamines (including methamphetamine), cathinones (i.e., bath salts), MDMA (ecstasy), nicotine, and caffeine. At rather low doses, alcohol use is associated with feelings of euphoria. Opioids have analgesic properties; that is, they decrease pain. Like all opioids, codeine does have abuse potential. For individuals who are especially open to the power of suggestion, hypnosis can prove to be a very effective technique, and brain imaging studies have demonstrated that hypnotic states are associated with global changes in brain functioning (Del Casale et al., 2012; Guldenmund, Vanhaudenhuyse, Boly, Laureys, & Soddu, 2012). We experience different states of consciousness and different levels of awareness on a regular basis. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. The term was first coined by a physiologist named Walter Cannon in 1926. (credit sleeping: modification of work by Ryan Vaarsi). A sleep deprived individual generally will fall asleep more quickly than if she were not sleep deprived. A neighbor called the police after witnessing Falater standing over his wifes body before dragging her into the pool. The participant is encouraged to use his or her imagination. Individuals who suffer from RBD have high levels of physical activity during REM sleep, especially during disturbing dreams. Again, this is an intuitive and appealing explanation for why we sleep. This treatment option has proven to be effective for people suffering from mild to severe cases of sleep apnea (McDaid et al., 2009). This pattern of brain wave activity resembles that of someone who is very relaxed, yet awake. Given that college students are notorious for suffering from significant sleep debt (Hicks, Fernandez, & Pelligrini, 2001; Hicks, Johnson, & Pelligrini, 1992; Miller, Shattuck, & Matsangas, 2010), chances are you and your classmates deal with sleep debt-related issues on a regular basis. Unfortunately, this is not the case; however, several hypotheses have been proposed to explain the function of sleep. How exactly does a hypnotist bring a participant to a state of hypnosis? These kinds of schedules are common for individuals working in health care professions and service industries, and they are associated with persistent feelings of exhaustion and agitation that can make someone more prone to making mistakes on the job (Gold et al., 1992; Presser, 1995). Jet lagis a collection of symptoms that results from the mismatch between our internal circadian cycles and our environment. This chart illustrates the circadian change in body temperature over 28 hours in a group of eight young men. Aches and pains, such as severe headache and muscle and joint pain. Some animals never sleep (e.g., some fish and amphibian species); other animals sleep very little without apparent negative consequences (e.g., giraffes); yet some animals (e.g., rats) die after two weeks of sleep deprivation (Siegel, 2008). Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a rare but severe, often fatal illness in humans. During sleep, the pituitary gland secretes both FSH and LH which are important in regulating the reproductive system (Christensen et al., 2012; Sofikitis et al., 2008). Although there are a number of different techniques in use, the central feature of all meditation is clearing the mind in order to achieve a state of relaxed awareness and focus (Chen et al., 2013; Lang et al., 2012). that would be one of the problems that Ive encountered. Jet lag is a collection of symptoms that results from the mismatch between our internal circadian cycles and our environment.

This final section will consider hypnotic and meditative states as additional examples of altered states of consciousness experienced by some individuals. The average EVD case fatality rate is around 50%. These effects can occur as a function of accumulated sleep debt or in response to more acute periods of sleep deprivation. Like NREM sleep, REM has been implicated in various aspects of learning and memory (Wagner, Gais, & Born, 2001; Siegel, 2001). In terms of brain wave activity, stage 1 sleep is associated with both alpha and theta waves. Chapter 5: Indoor Air Pollutants and Toxic Materials As the dose increases, people report feeling sedated. In the central nervous system, it plays a role in arousal and reward mechanisms. An agonist facilitates the activity of a neurotransmitter system, and antagonists impede neurotransmitter activity. These individual differences in circadian patterns of activity are known as a persons chronotype, and research demonstrates that morning larks and night owls differ with regard to sleep regulation (Taillard, Philip, Coste, Sagaspe, & Bioulac, 2003). Sleepis 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. c. absence of subjective symptoms of disease. If you lie down to take a nap and fall asleep very easily, chances are you may have sleep debt. Biological rhythmsare internal rhythms of biological activity. In fact, abuse of prescription opioid medications is becoming a major concern worldwide (Aquina, Marques-Baptista, Bridgeman, & Merlin, 2009; Casati, Sedefov, & Pfeiffer-Gerschel, 2012). (b) People practicing meditation may experience an alternate state of consciousness. For example, most people sleep during the night and are awake during the day. These symptoms include fatigue, sluggishness, irritability, and insomnia (i.e., a consistent difficulty in falling or staying asleep for at least three nights a week over a month's time) (Roth, 2007). It is also associated with paralysis of muscle systems in the body with the exception of those that make circulation and respiration possible. The first three stages of sleep are NREM sleep, while the fourth and final stage of sleep is REM sleep. The hypnogram below (Figure 4.12) shows a persons passage through the stages of sleep. (credit: modification of work by new 1lluminati/Flickr), Medical marijuana shops are becoming more and more common in the United States. It is not uncommon for people suffering from insomnia to experience increased levels of anxiety about their inability to fall asleep. Chronic insomnia is almost always associated with feeling overtired and may be associated with symptoms of depression. Sleep-wake cycles seem to be controlled by multiple brain areas acting in conjunction with one another. Reduced urine. . That includes exercise and bright light from devices. d. both b and c. 2. This will be followed by brief descriptions of the effects of some of the more well-known drugs commonly used today. While there is tremendous variation in any given individuals sleep needs, the National Sleep Foundation (n.d.) cites research to estimate that newborns require the most sleep (between 12 and 18 hours a night) and that this amount declines to just 79 hours by the time we are adults. Given the average life expectancy for U.S. citizens falls between 73 and 79 years old (Singh & Siahpush, 2006), we can expect to spend approximately 25 years of our lives sleeping. While we have discussed the negative outcomes associated with sleep deprivation, it should be pointed out that there are many benefits that are associated with adequate amounts of sleep. There may be many factors that contribute to insomnia, including age, drug use, exercise, mental status, and bedtime routines. Rotating shift workrefers to a work schedule that changes from early to late on a daily or weekly basis. Common definitions of health include: a. optimal weight and endurance. If we have biological rhythms, then is there some sort ofbiological clock? By the late 19th century, German psychiatrist SigmundFreudhad become convinced that dreams represented an opportunity to gain access to the unconscious. Generally, people use caffeine to maintain increased levels of alertness and arousal. In 2013, the U.S. Food and Drug Administration recommended tighter controls on their medical use. Freud made distinctions between the manifest content and the latent content of dreams. Devices like this are designed to provide exposure to bright light to help people maintain a regular circadian cycle. As mentioned earlier, lack of sleep can result in decreased mental alertness and cognitive function. That is why individuals suffering from sleep deprivation can also put themselves and others at risk when they put themselves behind the wheel of a car or work with dangerous machinery. Case fatality rates have varied from 25% to 90 . Thus we sleep in safe areas to reduce the chance of harm.
