Drugs are chemical substances that, when taken alter the structure or functioning of the body in some way. (a) A typical CPAP device used in the treatment of sleep apnea is (b) affixed to the head with straps, and a mask that covers the nose and mouth. A K-complex is a very high amplitude pattern of brain activity that may in some cases occur in response to environmental stimuli.   It describes induced changes in one's mental state, almost always temporary. Physiologically, the body can become addicted to opiate drugs in less than a week, including when taken as prescribed. Heroin can be snorted, smoked, or injected intravenously. Whether lark, owl, or somewhere in between, there are situations in which a person’s circadian clock gets out of synchrony with the external environment. Match. episodic memory). The theory further proposes that via pharmacological induction of psychedelic substances psilocybin, the brain is able to enter into the primary state of consciousness (the psychedelic state) from normal waking consciousness. Sacks, Oliver W. A leg to stand on (New York : Summit Books, 1984). 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). This altered state of consciousness can produce real feelings and/or memories. Blurred vision, hallucinations, timelessness, loss of control, new insights 4. These drugs promote increased levels of neural activity. Theta waves still dominate the activity of the brain, but they are interrupted by brief bursts of activity known as sleep spindles (Figure 4.9). Hi Roman. The first stage of NREM sleep is known as stage 1 sleep. Aside from their utility as analgesic drugs, opioid-like compounds are often found in cough suppressants, anti-nausea, and anti-diarrhea medications. This is exactly when an altered state of consciousness is experienced.. 2005). This integration allows pre-linguistic and basic body-level knowledge to surface in the mind, allowing for a greatly “increased coherence of the potentials of many parts of the brain” (482), according to Winkelman. This can lead to people compulsively using stimulants such as cocaine and amphetamines, in part to try to reestablish the person’s physical and psychological pre-use baseline. Depletion of certain neurotransmitters can lead to mood dysphoria, cognitive problems, and other factors. schizophrenia. Historically, somnambulism has been treated with a variety of pharmacotherapies ranging from benzodiazepines to antidepressants. Brain waves during REM sleep appear very similar to brain waves during wakefulness. Third, the alteration between normal and altered states can be spontaneous (road hypnosis), induced by lack of external stimuli (isolation) or by sensory overload hypnotherapy), or self-induced (meditation, self-hypnosis). Like hypnosis, meditation also shows promise in stress management, sleep quality (Caldwell, Harrison, Adams, Quin, & Greeson, 2010), treatment of mood and anxiety disorders (Chen et al., 2013; Freeman et al., 2010; Vøllestad, Nielsen, & Nielsen, 2012), and pain management (Reiner, Tibi, & Lipsitz, 2013). We also alter our consciousness through the use of various psychoactive drugs. Examples include impact to the brain caused by blunt force (i.e., a car accident). To account for an ASC, multiple dimensions need to be altered. In recent years, methamphetamine (meth) use has become increasingly widespread. For 19 Ss a condition of sensory overload induced several kinds of altered states of consciousness. It is also evoked by a class of anaesthetic drug, and can occur in epilepsy. theory of mind), remembering the past and thinking about the future (e.g. For example, Hobson (2009) suggests that dreaming may represent a state of protoconsciousness. The findings of the famous Good Friday Experiment by Pahnke suggest that mystical experiences can be triggered by psilocybin. Hypnosis is a state of extreme self-focus and attention in which minimal attention is given to external stimuli. Neurotransmitters can cause inhibitory or excitatory effects on the "target" cell they are affecting. Sleep Deprivation. Medical marijuana is marijuana that is prescribed by a doctor for the treatment of a health condition. The reason a traumatic experience causes altered states of consciousness is that it changes how the brain works. Like NREM sleep, REM has been implicated in various aspects of learning and memory (Wagner, Gais, & Born, 2001; Siegel, 2001). The social change of the turbulent 1960s has decisively led to a change of the scientific perspective to the point that introspection as a scientific method and ASCs as valid realms of experience became more widely accepted. Entoptic images are visual effects which originate within the visual processing system of the observer. Although she did not experience any dream-like hallucinations, she was diagnosed with narcolepsy as a result of sleep testing. Moreover, these impairments become more severe as the amount of sleep deprivation increases (Alhola & Polo-Kantola, 2007). Altered States of Consciousness - through Drugs. Various researchers have attempted the classification into a broader framework. Chronic insomnia is almost always associated with feeling overtired and may be associated with symptoms of depression. You have read that sleep is distinguished by low levels of physical activity and reduced sensory awareness. As you will learn when you study social roles, people’s behavior can be shaped by their expectations of how they should act in a given situation. Thus, opioid drugs, which mimic this endogenous painkilling mechanism, have an extremely high potential for abuse. In 2012, Kromann and Nielson reported on a case study of a 40-year-old woman who suffered significant ill effects from her use of caffeine. Cocaine inhibits the reuptake of norepinephrine, serotonin, dopamine, and other neurotransmitters in the synapse, resulting in an altered state of consciousness or a “high” (Aldridge, D., & Fachner, J. ö. Reviewing the previous conditions for accidental and pathological causes, we can come to understand that all of these accidental or pathological causes share the component of reduced self-awareness. Spell. and P.J. If we have biological rhythms, then is there some sort of biological clock? High doses can induce sleep, cause motor disturbance, memory loss, decreased respiratory function, and death. Humans have an endogenous opioid neurotransmitter system—the body makes small quantities of opioid compounds that bind to opioid receptors reducing pain and producing euphoria. There was a significant positive correlation between the degree to which women thought about their former spouses during waking hours and the number of times their former spouses appeared as characters in their dreams (Cartwright, Agargun, Kirkby, & Friedman, 2006). "a unique, dynamic pattern or configuration of psychological structures" (Tart,1969). Psychotic episodes often include delusions, paranoia, derealization, depersonalization, and hallucinations (Revonsuo et al., 2008). Hypnosis . The altered states of consciousness that can be produced by isolation, The participant is encouraged to use his or her imagination. Alcohol, barbiturates (e.g., secobarbital, pentobarbital), Benzodiazepines (e.g., Xanax). (Humphrey, N. 2001) This may cause one to experience many levels of altered consciousness. These synthetic drugs are so potent that even small doses can cause overdose and death. This is an important factor because we can develop tolerance and experience withdrawal from any number of drugs that we do not abuse. T –good definition 2. Frequently altered states of consciousness either are induced personally or by others which may or may not produce lasting effects. One complete menstrual cycle takes about 28 days—a lunar month—but many biological cycles are much shorter. Surprisingly, narcoleptic episodes are often triggered by states of heightened arousal or stress. Stimulant users seek a euphoric high, feelings of intense elation and pleasure, especially in those users who take the drug via intravenous injection or smoking. It can sometimes be reached intentionally by the use of a sensory deprivation tank or mind-control techniques, hypnosis, meditation, prayer, or disciplines e g Mantra Meditation, … Unlike the other sleep disorders described in this section, a person with narcolepsy cannot resist falling asleep at inopportune times. Chapter 10 of. ASCs are a basic human need. By the late 19th century, German psychiatrist Sigmund Freud had become convinced that dreams represented an opportunity to gain access to the unconscious. 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. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is used by clinicians to diagnose individuals suffering from various psychological disorders. As an individual continues through stage 1 sleep, there is an increase in theta wave activity. An MRI study conducted at Harvard Medical school in 2007, found that a sleep-deprived brain was not capable of being in control of its sensorimotor functions, leading to an impairment to the patient's self-awareness. 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. (pp. Altered states of consciousness by Tart, Charles T., 1937- comp. The crisis actually began in the 1990s, when pharmaceutical companies began mass-marketing pain-relieving opioid drugs like OxyContin with the promise (now known to be false) that they were non-addictive. Suppressing this stimulant results in a similar type of physiological slowdown. normal state. 2005). Psychoactive drugs change the way in which chemicals allow neurons to communicate with each other. It can be triggered by the drug ketamine, and can occur before a seizure in epilepsy. Sleep rebound refers to the fact that a sleep-deprived individual will fall asleep more quickly during subsequent opportunities for sleep. The next item of interest is oxygen deficiency, questioning how oxygen deficiency impacts the brain is an important part of comprehending why ASC occurs when there is oxygen deprivation in an environment. This variability of experience is considered as normal fluctuation, while any state that is experienced to diverge significantly from it can be called an ASC. Opioids are a class of drugs that alter consciousness. Given that withdrawal from a drug often involves an experience opposite to the effect of the drug, it should be no surprise that opioid withdrawal resembles a severe case of the flu. As we grow older, we sleep less. For example, withdrawal from sedative drugs often produces unpleasant arousal and agitation. Further, Ken Wilber proposes a multidimensional system and adds that the individual experience of an ASC is shaped by a person's unique psychological development. Several of the nurses interviewed commented that their work schedules affected their relationships with their family. The Impairment becomes visible the moment seizures begin to occur, this is when the patient enters the altered state of consciousness. 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. This chapter will discuss states of consciousness with a particular emphasis on sleep. (a) A period of rapid eye movement is marked by the short red line segment. Codeine is an opioid with relatively low potency. They can be helpful for people working night shifts or for people affected by seasonal variations in light. 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). In addition to withdrawal, many individuals who are diagnosed with substance use disorders will also develop tolerance to these substances. Why bother with altered states of consciousness? 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. An altered state of consciousness (ASC), also called altered state of mind or mind alteration, is any condition which is significantly different from a normal waking state. Participants were told they would not feel pain, but they could press a button if they did; while they reported not feeling pain, they did, in fact, press the button, suggesting a dissociation of consciousness while in the hypnotic state (Hilgard & Hilgard, 1994). Daydream _____ is an altered state of consciousness where the person is more open to suggestions. Perhaps our ancestors spent extended periods of time asleep to reduce attention to themselves from potential predators. Opioids produce analgesia and often feelings of euphoria in users. Examples of opioids include heroin, morphine, hydrocodone, and oxycodone. . You can test out of the Meditation is a repetitive practice used to help people train their attention. The brain waves associated with REM sleep, outlined in the red box in (a), look very similar to those seen (b) during wakefulness. A sleep spindle is a rapid burst of higher frequency brain waves that may be important for learning and memory (Fogel & Smith, 2011; Poe, Walsh, & Bjorness, 2010). As a result, many of us sleep less than 7–8 hours a night and accrue a sleep debt. Tolerance is linked to physiological dependence, and it occurs when a person requires more and more drug to achieve effects previously experienced at lower doses. During periods of sleepwalking, sleepers often have their eyes open, but they are not responsive to attempts to communicate with them. The different stages of sleep will be identified, and sleep disorders will be described. , Cannabis is a psychoactive drug that is known to alter the state of consciousness.  In order to define an ASC, Tart focuses on the importance of subjective experience. The participant is made comfortable and is directed to be relaxed and sleepy. In the central nervous system, it plays a role in arousal and reward mechanisms.  Followers of various shamanic traditions "enter altered states of consciousness in order to serve their community. 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. Stimulants are drugs that tend to increase overall levels of neural activity. Biological rhythms are internal rhythms of biological activity. High doses increase agitation, paranoia, can cause hallucinations. Jet lag is a collection of symptoms that results from the mismatch between our internal circadian cycles and our environment. Night terrors apparently occur during the NREM phase of sleep (Provini, Tinuper, Bisulli, & Lagaresi, 2011). 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). Stage 1 sleep is a transitional phase that occurs between wakefulness and sleep, the period during which we drift off to sleep. There is no general definition of an altered state of consciousness, as any definitional attempt would firstly have to rely on a definition of a normal state of consciousness. Other depressants include barbiturates and benzodiazepines. , Another pathological cause is psychosis, otherwise known as a psychotic episode. In fact, abuse of prescription opioid medications is becoming a major concern worldwide (Aquina, Marques-Baptista, Bridgeman, & Merlin, 2009; Casati, Sedefov, & Pfeiffer-Gerschel, 2012). the individual ratings, or factor scores, of a questionnaire.
