It is much more difficult to awaken someone from sleep during stage 3 than during earlier stages. Methamphetamineis a type of amphetamine that can be made from ingredients that are readily available (e.g., medications containing pseudoephedrine, a compound found in many over-the-counter cold and flu remedies). Recent research (Horikawa, Tamaki, Miyawaki, & Kamitani, 2013) has uncovered new techniques by which researchers may effectively detect and classify the visual images that occur during dreaming by using fMRI for neural measurement of brain activity patterns, opening the way for additional research in this area. It may feel like alcohol helps you sleep, but it actually disrupts REM sleep and leads to frequent awakenings. Caffeine is an adenosine antagonist, so caffeine inhibits the adenosine receptors, thus decreasing sleepiness and promoting wakefulness. (credit: modification of work by Mikael Hggstrm). The body maintains homeostasis for many factors in addition to temperature. c. are influenced by peer pressure, often leading to unhealthful or unsafe behaviors. The tendency to maintain a stable, relatively constant internal environment is called homeostasis. Cognitive-behavioral therapyis a type of psychotherapy that focuses on cognitive processes and problem behaviors. The sleep and dreaming researcher Rosalind Cartwright, however, believes that dreams simply reflect life events that are important to the dreamer. We spend approximately one-third of our lives sleeping. There are a variety of drugs that treat restless leg syndrome: benzodiazepines, opiates, and anticonvulsants (Restless Legs Syndrome Foundation, n.d.). As a group, hallucinogens are incredibly varied in terms of the neurotransmitter systems they affect. In contrast,non-REM (NREM)sleep is subdivided into four stages distinguished from each other and from wakefulness by characteristic patterns of brain waves. A person with asleep debtdoes not get sufficient sleep on a chronic basis. Beyond being awake or asleep, there are many other states of consciousness people experience. Avoid alcohol, cigarettes, caffeine, and heavy meals before bed. The internal state of an object is the set of all its attributes' values. For example, she and her colleagues published a study in which women going through divorce were asked several times over a five-month period to report the degree to which their former spouses were on their minds. 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). Caffeine is found in many common medicines (such as weight loss drugs), beverages, foods, and even cosmetics (Herman & Herman, 2013). Question 2 1 / 1 pts Ling Fan finds that she has a difficult time tolerating alcohol and prefers to not even have small amounts , as she often becomes flushed , warm , and nauseous .Most likely , Ling Fan , like many other women and those of Asian descent , lacks the enzyme called alcohol _ _ _____. This chapter will discuss states of consciousness with a particular emphasis on sleep. Users can experience physical symptoms that include nausea, elevated blood pressure, and increased heart rate. Homeostasisis the tendency to maintain a balance, or optimal level, within a biological system. It was getting to the point where it was kind of scary (Henry & Rosenthal, 2013, p. 52). 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. 1. High doses can cause death due to respiratory depression. Night terrorsresult in a sense of panic in the sufferer and are often accompanied by screams and attempts to escape from the immediate environment (Mahowald & Schenck, 2000). EVERYDAY CONNECTION: Solutions to Support Healthy Sleep, continuous positive airway pressure (CPAP). The Safe to Sleep campaign educates the public about how to minimize risk factors associated with SIDS. Is it absolutely essential that we sleep? Opioid addiction reached crisis levels in the United States such that by 2019, an average of 130 people diedeach dayof an opioid overdose (NIDA, 2019). A person who has a substance use disorder often uses more of the substance than they originally intended to and continues to use that substance despite experiencing significant adverse consequences. AK-complexis a very high amplitude pattern of brain activity that may in some cases occur in response to environmental stimuli. Some forms of psychotherapy, such as cognitive-behavioral therapy, can help sufferers of insomnia. (credit sleeping: modification of work by Ryan Vaarsi). (West et al., 2009, p. 114). It is often prescribed for minor pain, and it is available over-the-counter in some other countries. Withdrawal from opioids includes pain, which patients often misinterpret as pain caused by the problem that led to the original prescription, and which motivates patients to continue using the drugs. Melatonin release is stimulated by darkness and inhibited by light. All of the following are true statements concerning the health of Americans EXCEPT: a. mortality rates from smoking have declined. week 3 midterm 1.docx - Question 1 1 / 1 pts John has been Thirst. Freud made distinctions between the manifest content and the latent content of dreams. A) a mole that looks cancerous B) nasal congestion C) change in heart rate D) issues with breathing Which of the following American health care systems is most known for requiring a referral from a primary care doctor in order to see a specialist? Therefore, it is important to make a distinction between hypnosis as an empirically based therapeutic approach versus as a form of entertainment. 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). One complete menstrual cycle takes about 28 daysa lunar monthbut many biological cycles are much shorter. Chapter 5: Indoor Air Pollutants and Toxic Materials In 2015, the National Sleep Foundation updated their sleep duration hours, to better accommodate individual differences. Confusion. 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. Those who continue to have insomnia, particularly if it affects their quality of life, should seek professional treatment. He suffered from no apparent anatomical brain anomalies or psychological disorders. In addition, these drugs can cause feelings of anxiety, hallucinations, and paranoia (Fiorentini et al., 2011). It appeared that Scott Falater had killed his wife in his sleep, or at least, that is the defense he used when he was tried for his wifes murder (Cartwright, 2004; CNN, 1999). While medical marijuana laws have been passed on a state-by-state basis, federal laws still classify this as an illicit substance, making conducting research on the potentially beneficial medicinal uses of marijuana problematic. However, alternative treatment options are being explored because consistent compliance by users of CPAP devices is a problem. Thepineal gland, an endocrine structure located inside the brain that releases melatonin, is thought to be involved in the regulation of various biological rhythms and of the immune system during sleep (Hardeland, Pandi-Perumal, & Cardinali, 2006). Methadone clinicshelp people who previously struggled with opioid addiction manage withdrawal symptoms through the use of methadone. The brains clock mechanism is located in an area of the hypothalamus known as thesuprachiasmatic nucleus (SCN). Generally, narcolepsy is treated using psychomotor stimulant drugs, such as amphetamines (Mignot, 2012). Yarmila Falaters body was found in the familys pool with 44 stab wounds. 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. Opioids have analgesic properties; that is, they decrease pain. d. both b and c. 2. 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). One particular aspect of the internal state is that a method applied to the object being in a defined internal state (= a specific set of all its attributes' value) will result in another, also defined (and reproducible) internal state. 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. Here are some tips to maintain healthy sleep: Aparasomniais one of a group of sleep disorders in which unwanted, disruptive motor activity and/or experiences during sleep play a role. This hypnogram illustrates how an individual moves through the various stages of sleep. Popular portrayals of hypnosis have led to some widely-held misconceptions. Clonazepam, an anti-anxiety medication with sedative properties, is most often used to treat RBD. Furthermore, slow-wave sleep after learning a new task can improve resultant performance on that task (Huber, Ghilardi, Massimini, & Tononi, 2004) and seems essential for effective memory formation (Stickgold, 2005). Not able to pass stool or gas. 3. Generally, alcohol is associated with decreases in reaction time and visual acuity, lowered levels of alertness, and reduction in behavioral control. You were capable of engaging in the all of the complex tasks involved with operating a motor vehicle even though you were not aware of doing so. Getting the optimal amount of sleep has also been associated with other cognitive benefits. Again, this is an intuitive and appealing explanation for why we sleep. In this section, we will discuss each of these stages of sleep and their associated patterns of brain wave activity. The typical positive symptoms of schizophrenia , such as hallucinatory experiences or fixed delusional beliefs, tend to be very upsetting and disruptivenot a positive experience at all for you or someone you care about who is experiencing them. During periods of sleepwalking, sleepers often have their eyes open, but they are not responsive to attempts to communicate with them. As we grow older, we sleep less. Some people also experience altered states of consciousness through meditation, hypnosis, or alcohol and other drugs. There may be many factors that contribute to insomnia, including age, drug use, exercise, mental status, and bedtime routines. As he went to investigate what was going on, he was met by a group of police officers who arrested him for the murder of his wife (Cartwright, 2004; CNN, 1999). She indicated that she had fallen asleep at inappropriate or dangerous times, including while eating, while socializing with friends, and while driving her car. Aside from their utility as analgesic drugs, opioid-like compounds are often found in cough suppressants, anti-nausea, and anti-diarrhea medications. Upset stomach and vomiting. While people are often unaware of their sleep apnea, they are keenly aware of some of the adverse consequences of insufficient sleep. The following describe internal states of symptoms EXCEPT? As discussed by Siegel (2008), a definition of sleep must also include mention of the interplay of the circadian and homeostatic mechanisms that regulate sleep. Loss of appetite. Add a comment. Primary signs and symptoms of Ebola often include some or several of the following: Fever. 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. Homeostasis refers to the body's need to reach and maintain a certain state of equilibrium. During this time, there is a slowdown in both the rates of respiration and heartbeat. Bloating or a feeling of fullness in the abdomen. Hypnosis in conjunction with other techniques is used for a variety of therapeutic purposes and has shown to be at least somewhat effective for pain management, treatment of depression and anxiety, smoking cessation, and weight loss (Alladin, 2012; Elkins, Johnson, & Fisher, 2012; Golden, 2012; Montgomery, Schnur, & Kravits, 2012). The suprachiasmatic nucleus (SCN) serves as the brains clock mechanism. In such instances, the individuals schedule changes so frequently that it becomes difficult for a normal circadian rhythm to be maintained. The following describe internal states of symptoms EXCEPT? Perhaps our ancestors spent extended periods of time asleep to reduce attention to themselves from potential predators. As already mentioned, the hypothalamus contains the SCNthe biological clock of the bodyin addition to other nuclei that, in conjunction with the thalamus, regulate slow-wave sleep. Post-Traumatic Stress Disorder (Symptoms) | Center for the Treatment However, all of their somnambulistic patients who also suffered from sleep-related breathing problems showed a marked decrease in sleepwalking when their breathing problems were effectively treated. 1. A hypnogram is a diagram of the stages of sleep as they occur during a period of sleep. Like NREM sleep, REM has been implicated in various aspects of learning and memory (Wagner, Gais, & Born, 2001; Siegel, 2001). (credit: modification of work by new 1lluminati/Flickr), Medical marijuana shops are becoming more and more common in the United States. Not surprisingly, insomnia treatment may take one of several different approaches. Stage 1 sleepis a transitional phase that occurs between wakefulness and sleep, the period during which we drift off to sleep. In addition, stage 1 sleep involves a marked decrease in both overall muscle tension and core body temperature. Two of them I didnt even know I was involved in until afterwards (Henry & Rosenthal, 2013, p. 52). This is known as the REM rebound, and it suggests that REM sleep is also homeostatically regulated. Consider a patient who believed that as a result of his sleep apnea he had three car accidents in six weeks. These symptoms usually are opposite of the effects of the drug. Individuals who do rotating shift work are also likely to experience disruptions in circadian cycles. 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. Sleepwalking, restless leg syndrome, and night terrors are all examples of parasomnias (Mahowald & Schenck, 2000). 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). Furthermore, these types of behaviors ultimately disrupt sleep, although affected individuals have no memories that these behaviors have occurred (Arnulf, 2012). Identifying Internal States of the Brain | Technology Networks However, the success rate of such treatments is questionable. Although individuals suffering from night terrors appear to be awake, they generally have no memories of the events that occurred, and attempts to console them are ineffective. While it is probably the most commonly used drug in the world, the potency of this particular drug pales in comparison to the other stimulant drugs described in this section. Homeostasis: How the Body Strives for Balance - Verywell Mind Infants younger than 12 months appear to be at the highest risk for SIDS, and boys have a greater risk than girls. This campaign is sponsored in part by the National Institute of Child Health and Human Development. Recommendations like these have helped to decrease the number of infant deaths from SIDS in recent years (Mitchell, 2009; Task Force on Sudden Infant Death Syndrome, 2011). In some cases, though, there may be no symptoms of inflammation at all. With repeated use of many central nervous system depressants, such as alcohol, a person becomes physically dependent upon the substance and will exhibit signs of both tolerance and withdrawal. Keep your bedroom temperature between 60 and 67 degrees. Methamphetamine addiction produces an intense craving that is difficult to treat. The pons is important for regulating rapid eye movement (REM) sleep (National Institutes of Health, n.d.). Drugs in this category include cocaine, amphetamines (including methamphetamine), cathinones (i.e., bath salts), MDMA (ecstasy), nicotine, and caffeine. For example, withdrawal from sedative drugs often produces unpleasant arousal and agitation. Given the central role that sleep plays in our lives and the number of adverse consequences that have been associated with sleep deprivation, one would think that we would have a clear understanding of why it is that we sleep. It is quite possible that sleep serves no single universally adaptive function, and different species have evolved different patterns of sleep in response to their unique evolutionary pressures. You don't have to be a psychologist to know that conditions like hunger or fatigue have an impact on thinking and decision-making; these are examples of internal states. 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. 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. Treatment. 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. Infants should not have caps placed on their heads when put down to sleep in order to prevent overheating, and people in the childs household should abstain from smoking in the home. This pattern of temperature fluctuation, which repeats every day, is one example of a circadian rhythm. The pineal and pituitary glands secrete a number of hormones during sleep. For instance, have you ever daydreamed while driving home from work or school without really thinking about the drive itself? 1. There is quite a bit of controversy within the scientific community as to the extent to which marijuana might have medicinal benefits due to a lack of large-scale, controlled research (Bostwick, 2012). 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). Stage 3is often referred to as deep sleep or slow-wave sleep because this stage is characterized by low frequency (less than 3 Hz), high amplitudedelta waves(Figure 4.10). Like many other stimulants, cocaine agonizes the dopamine neurotransmitter system by blocking the reuptake of dopamine in the neuronal synapse. If you get peritoneal dialysis, peritonitis symptoms also may include: Cloudy dialysis fluid. In general, these drugs are not thought to possess the same sort of abuse potential as other classes of drugs discussed in this section. The brain waves associated with this stage of sleep are very similar to those observed when a person is awake, as shown inFigure 4.11, and this is the period of sleep in which dreaming occurs. MDMA (3.4-methelynedioxy-methamphetamine, commonly known as ecstasy or Molly) is a mild stimulant with perception-altering effects. While awake, we feel alert and aware of the many important things going on around us. One or two nights of sleep difficulty is not unusual, but if you experience anything more than that, you should seek a doctors advice. Brainwave activity changes dramatically across the different stages of sleep. Recent adaptations (e.g., Hobson, 2002) continue to update the theory based on accumulating evidence. Two theories attempt to answer this question: One theory views hypnosis as dissociation and the other theory views it as the performance of a social role. Meditationis the act of focusing on a single target (such as the breath or a repeated sound) to increase awareness of the moment. In some cases, users experience vivid visual hallucinations. Remarkably, Falater insisted that he had no recollection of hurting his wife in any way. Thecollective unconscious, as described byJung, is a theoretical repository of information he believed to be shared by everyone. If we have biological rhythms, then is there some sort ofbiological clock? Understanding the impact of sleep on cognitive function should help you understand that cramming all night for a test may be not effective and can even prove counterproductive. 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. We might even describe consciousness as a continuum that ranges from full awareness to a deep sleep. Freud was not the only theorist to focus on the content of dreams. a. will be healthier than children because they are exposed to fewer infectious diseases.b. It is also associated with paralysis of muscle systems in the body with the exception of those that make circulation and respiration possible. In Hilgards experiments, he induced participants into a state of hypnosis, and placed their arms into ice water. Physiologically, the body can become addicted to opiate drugs in less than a week, including when taken as prescribed. They named each of the three states: "Close," when a male is closer than average to a female and approaching her slowly; "Chasing," when he is approaching quickly; and "Whatever," when he is facing away from her and moving slowly. These symptoms include fatigue, sluggishness, irritability, andinsomnia(i.e., a consistent difficulty in falling or staying asleep for at least three nights a week over a months time) (Roth, 2007). Site has information/education resources on a broad range of topics, including asthma, birth defects, radiation, sanitation, lead in blood, and more. The consequences of sleep debt include decreased levels of alertness and mental efficiency. Sleep debt and sleep deprivation have significant negative psychological and physiological consequencesFigure 4.5. 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.). If someone stays awake for 48 consecutive hours, they could start to hallucinate. In the central nervous system, it plays a role in arousal and reward mechanisms. Drugwithdrawalincludes a variety of negative symptoms experienced when drug use is discontinued. Psychological dependence on these drugs is also possible. 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). We experience different states of consciousness and different levels of awareness on a regular basis. Neurogenic shock is caused by damage to the central nervous system, usually a spinal cord injury. b. absence of signs of malfunctioning. Aside from the role that REM sleep may play in processes related to learning and memory, REM sleep may also be involved in emotional processing and regulation. In such instances, REM rebound may actually represent an adaptive response to stress in non-depressed individuals by suppressing the emotional salience of aversive events that occurred in wakefulness (Suchecki, Tiba, & Machado, 2012). As mentioned earlier, lack of sleep can result in decreased mental alertness and cognitive function. Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a rare but severe, often fatal illness in humans. This discomfort is relieved by deliberately moving the legs, which, not surprisingly, contributes to difficulty in falling or staying asleep. It is not uncommon for people suffering from insomnia to experience increased levels of anxiety about their inability to fall asleep. Elements that are known to make PTSD more likely are the following: Perceived life threat Personal injury Interpersonal violence, particularly perpetrated by a caregiver Past and present vulnerability, including genetics, childhood trauma, insufficient emotional support, concurrent causes of stress Example: Childhood abuse and rape THE INTERNAL STATE SCALE (ISS) Version 2 and the ChronoBook SCORING KEY AND SUMMARY Mark S. Bauer, MD . As one of their mechanisms of action, cocaine and amphetamines block the reuptake of dopamine from the synapse into the presynaptic cell. When he told me, I made him go see the college therapist. . These will soon, in all ordinary cases, subdue the most distressing symptoms, and effect a perfect cure in a day or two. This section will describe several sleep disorders as well as some of their treatment options. 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. For instance, if a woman dreams about being chased by a snake, Freud might have argued that this represents the womans fear of sexual intimacy, with the snake serving as a symbol of a mans penis. Unlike Freud and Jung, Cartwrights ideas about dreaming have found empirical support. In a lucid dream, a person becomes aware of the fact that they are dreaming, and as such, they can control the dreams content (LaBerge, 1990). There are individual differences in regard to our sleep-wake cycle. Therefore, the abuse potential of central nervous system depressants is relatively high. . Methadoneis a synthetic opioid that is less euphorigenic than heroin and similar drugs. Train your body to associate the bed with sleeping rather than other activities like studying, eating, or watching television shows. Insudden infant death syndrome (SIDS)an infant stops breathing during sleep and dies. Medical marijuana is legal in over half of the United States and in the District of Columbia (Figure 4.19). How does hypnosis work? Alcohol, barbiturates (e.g., secobarbital, pentobarbital), Benzodiazepines (e.g., Xanax). Whether lark, owl, or somewhere in between, there are situations in which a persons circadian clock gets out of synchrony with the external environment. In fact, it has been suggested that there is no reason to think that energetic demands could not be addressed with periods of rest and inactivity (Frank, 2006; Rial et al., 2007), and some research has actually found a negative correlation between energetic demands and the amount of time spent sleeping (Capellini, Barton, McNamara, Preston, & Nunn, 2008). Acute alcohol administration results in a variety of changes to consciousness. the ability to spend time, good time with them when youre not feeling absolutely exhausted . A sleep deprived individual generally will fall asleep more quickly than if she were not sleep deprived. Rapid eye movement (REM)sleep is characterized by darting movements of the eyes under closed eyelids. (b) Heroin is cooked on a spoon over a candle. c++ - What is internal state? - Stack Overflow Diarrhea. Cocaine can be taken in multiple ways. Marijuana, LSD, Peyote, mescaline, DMT, dissociative anesthetics including ketamine and PCP, Increased heart rate and blood pressure that may dissipate over time, Mild to intense perceptual changes with high variability in effects based on strain, method of ingestion, and individual differences, Understand what is meant by consciousness, Explain how circadian rhythms are involved in regulating the sleep-wake cycle, and how circadian cycles can be disrupted, Describe areas of the brain involved in sleep, Understand hormone secretions associated with sleep, Describe several theories aimed at explaining the function of sleep, Differentiate between REM and non-REM sleep, Describe the differences between the three stages of non-REM sleep, Understand the role that REM and non-REM sleep play in learning and memory, Describe the symptoms and treatments of insomnia, Recognize the symptoms of several parasomnias, Describe the symptoms and treatments for sleep apnea, Recognize risk factors associated with sudden infant death syndrome (SIDS) and steps to prevent it, Describe the symptoms and treatments for narcolepsy.
