Our experiences change dramatically while we are in deep sleep and once again when we are dreaming. [19] They were pathologized and merely seen as symptoms of intoxication or demonic possession. Photic mind machines work with flickering lights embedded in sunglasses or a lamp that sits on a tripod above your head or facing you. Farthing's definition of an altered state of consciousness (ASC) is based on Charles Tart's terminology. 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. In fact, a meta-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). Despite recent changes in laws designed to make obtaining pseudoephedrine more difficult, methamphetamine continues to be an easily accessible and relatively inexpensive drug option (Shukla, Crump, & Chrisco, 2012). The first condition, traumatic experience, is defined as a lesion caused by an external force (Trauma. Stage 3 is often referred to as deep sleep or slow-wave sleep because this stage is characterized by low frequency (less than 3 Hz), high amplitude delta waves (Figure 4.10). (a) A period of rapid eye movement is marked by the short red line segment. 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. It is proposed that a general distinction can be made between two fundamentally different modes of cognition: Primary and secondary consciousness. This final section will consider hypnotic and meditative states as additional examples of altered states of consciousness experienced by some individuals. can be produced by drugs, trauma, fatigue, possibly hypnosis, and sensory deprivation Many of these processes, like much of psychological behavior, are rooted in our biology. Psychoactive drugs change the way in which chemicals allow neurons to communicate with each other. This is similar to the kind of paralysis experienced by healthy individuals during REM sleep (Burgess & Scammell, 2012; Hishikawa & Shimizu, 1995; Luppi et al., 2011). The work of Adolph Dittrich[26] aimed to empirically determine common underlying dimensions of consciousness altererations induced by different methods, such as drugs or non-pharmacological methods. These synthetic drugs are so potent that even small doses can cause overdose and death. 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. What are some examples of altered states of consciousness? Interdisciplinary research enterprises have set out to study the convergence of serotonergic and glutamatergic models of psychosis and dynamic neurotransmitter interactions, derived from the study of hallucinogenic drugs, in the future. Not surprisingly, insomnia treatment may take one of several different approaches. Interestingly, since the advent of electric light, the amount of sleep that people get has declined. This particular infection occurs in children and young adults. It is often prescribed for minor pain, and it is available over-the-counter in some other countries. [8] James' investigations into first-person-subjective-experience contributed to the reconsideration of introspection as a valuable research method in the academic community.[8]. To keep heroin affordable, many dealers began adding more potent synthetic opioids including fentanyl and carfentanyl to increase the effects of heroin. Some newer CPAP masks are smaller and cover only the nose. What are some examples of altered states of consciousness? [24] He also called for "state specific sciences"[10] in which researchers should do science on ASCs from within such states. You have read that sleep is distinguished by low levels of physical activity and reduced sensory awareness. The pituitary gland also secretes growth hormone, during sleep, which plays a role in physical growth and maturation as well as other metabolic processes (Bartke, Sun, & Longo, 2013). Various researchers have attempted the classification into a broader framework. People sleep better in cooler temperatures. The axons of light-sensitive neurons in the retina provide information to the SCN based on the amount of light present, allowing this internal clock to be synchronized with the outside world (Klein, Moore, & Reppert, 1991; Welsh, Takahashi, & Kay, 2010) (Figure 4.3). Blurred vision, hallucinations, timelessness, loss of control, new insights 4. Individuals who do rotating shift work are also likely to experience disruptions in circadian cycles. ... Altered State Consciousness. Acetylcholine functions as a neurotransmitter in motor neurons. This often results in sleeping problems, and it can lead to signs of depression and anxiety. The pineal 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). The early portion of stage 1 sleep produces alpha waves, which are relatively low frequency (8–13Hz), high amplitude patterns of electrical activity (waves) that become synchronized (Figure 4.8). Melatonin release is stimulated by darkness and inhibited by light. At rather low doses, alcohol use is associated with feelings of euphoria. 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). Popular portrayals of hypnosis have led to some widely-held misconceptions. [14][16], Meditation in its various forms is being rediscovered by modern psychology because of its therapeutic potential and its ability to "enable the activity of the mind to settle down". We spend approximately one-third of our lives sleeping. A sleep deprived individual generally will fall asleep more quickly than if she were not sleep deprived. Just as bears hibernate in the winter when resources are scarce, perhaps people sleep at night to reduce their energy expenditures. Secondary consciousness is associated with constrained cognition and more ordered neurodynamics. . LSD's main effects are emotional and psychological. That is, our brain acts as a reducing agent for the information that the world presents to our senses. 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. Starting from this Charles Tart focuses his definition on the subjective experience of a state of consciousness and its deviation from a normal waking state. For empirical research, such patterns correspond to a multivariate combination of independent 'consciousness factors', which can be quantified via questionnaires. Altered States of Consciousness can be produced by drugs, trauma, fatigue, possibly hypnosis, and sensory deprivation; ex. Some sleep-deprived individuals have difficulty staying awake when they stop moving (for example sitting and watching television or driving a car). 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. Hypnosis has also been used to draw out information believed to be buried deeply in someone’s memory. The next retrievable instance, by Dr Max Mailhouse from his 1904 presentation to conference,[3] however, is unequivocally identified as such, as it was in relation to epilepsy, and is still used today. 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. (Jayanthi & Ramamoorthy, 2005; Rothman, Blough, & Baumann, 2007). While opioid withdrawal can be extremely unpleasant, it is not life-threatening (Julien, 2005). "The Myth of Alpha Consciousness," Skeptical Inquirer, 10, no. The attempts of classification discussed in the following focus on slightly different aspects of ASCs. This is an important factor because we can develop tolerance and experience withdrawal from any number of drugs that we do not abuse. Alcohol alters consciousness by shifting levels of neurotransmitters. Sacks, Oliver W. Awakenings, [1st. In contrast, a person who has psychological dependence has an emotional, rather than physical, need for the drug and may use the drug to relieve psychological distress. Representing Altered States of Consciousness in Computer Arts Jonathan Weinel Glyndŵr University Plas Coch Campus, Mold Road, Wrexham, LL112AW North Wales, UK j.weinel@glyndwr.ac.uk It has been proposed that among the earliest known artworks produced by humans may have been representations of altered states of consciousness (ASCs). Train your body to associate the bed with sleeping rather than other activities like studying, eating, or watching television shows. Despite strong evidence linking serotonin and psychosis, novel research indicates that some behavioral effects of drugs such as psilocybin appear to be independent of the classical 5-HT2A receptor-agonist actions, implying that the model described here is not the only underlying framework at play. Because the biological clock is driven by light, exposure to bright light during working shifts and dark exposure when not working can help combat insomnia and symptoms of anxiety and depression (Huang, Tsai, Chen, & Hsu, 2013). Farthing adds to his definition that an ASC is short-termed or at least reversible and that it might not even be recognized as an ASC at that moment. While disruptions in circadian rhythms can have negative consequences, there are things we can do to help us realign our biological clocks with the external environment. It is administered alone or in conjunction with doses of melatonin (the hormone secreted by the pineal gland). [12], A recent working definition for empirical research is based on these previous definitions and provided by Schmidt.[7]. Obstructive sleep apnea occurs when an individual’s airway becomes blocked during sleep, and air is prevented from entering the lungs. Altered States of Consciousness The Division of Perceptual Studies is pursing research aimed at elucidating the relationship between the activities of a human mind and the multitude of physiological activities occurring in its associated brain and body functioning also known in the research literature as the ‘mind-brain problem’. 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. Methamphetamine is 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). The state of consciousness brought about by MDMA ingestion includes a rise in positive feelings and a reduction in negative feelings (Aldridge, D., & Fachner, J. ö. What are some features of altered states of consciousness? Among a variety of neurobiological evidence, John Hobson cites research on lucid dreams as an opportunity to better understand dreaming in general. Created by. 1 [1985]. Human consciousness can be altered in a number of different ways including through hypnosis, with drugs, and mental exercises. dissociation_____: “Split Consciousness” Drugs _tolerance_____: the diminishing effect with regular use of the same dose of a drug, requiring the user to take larger and larger doses … These effects can occur as a function of accumulated sleep debt or in response to more acute periods of sleep deprivation. During this time, an individual’s heart rate and respiration slow dramatically. Cannabis alters mental activity, memory, and pain perception. In such instances, the individual’s schedule changes so frequently that it becomes difficult for a normal circadian rhythm to be maintained. Beyerstein, Barry. It seems like everyone knows a friend, family member, or neighbor who has died of an overdose. But if you really want a powerful, fast, and direct way to get into a radically altered state, try taking a mind-altering drug, like LSD, peyote, or ayahuasca. Brainwave activity changes dramatically across the different stages of sleep. 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). There are a variety of drugs that treat restless leg syndrome: benzodiazepines, opiates, and anticonvulsants (Restless Legs Syndrome Foundation, n.d.). Brainwave activity changes dramatically across the different stages of sleep. Therefore, the abuse potential of central nervous system depressants is relatively high. Caffeine is another stimulant drug. The hypnogram below (Figure 4.12) shows a person’s passage through the stages of sleep. In central sleep apnea, disruption in signals sent from the brain that regulate breathing cause periods of interrupted breathing (White, 2005). 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). in the U.S.] (Garden City, N.Y., Doubleday, 1974). There are two types of sleep apnea: obstructive sleep apnea and central sleep apnea. [3] [4] It describes induced changes in one's mental state, almost always temporary. There are individual differences in regard to our sleep-wake cycle. Methamphetamine addiction produces an intense craving that is difficult to treat. Those who continue to have insomnia, particularly if it affects their quality of life, should seek professional treatment. "[note 1][10]. and P.J. A continuous positive airway pressure (CPAP) device includes a mask that fits over the sleeper’s nose and mouth, which is connected to a pump that pumps air into the person’s airways, forcing them to remain open, as shown in Figure 4.13. 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). [22] They focused on seemingly beneficial aspects of ASCs such as their potential to "promote creativity or treat addiction". It is much more difficult to awaken someone from sleep during stage 3 than during earlier stages. Studies have not been able to clearly identify when a person is reaching a higher level of risk for a psychotic episode (Schimmelmann, B., Walger, P., & Schultze-Lutter, F., 2013),[41] but the earlier people are treated for psychosis the more likely they are to avoid the devastating consequences which could lead to a psychotic disorder (Schimmelmann, B., Walger, P., & Schultze-Lutter, F., 2013). Charles Tart described an altered state of consciousness as a profound change in the "overall pattern of subjective experiences". Roberts, T.B. Historically, heroin has been a major opioid drug of abuse (Figure 4.17). Sleep Deprivation. Methadone clinics help people who previously struggled with opioid addiction manage withdrawal symptoms through the use of methadone. This final section will consider hypnotic and meditative states as additional examples of altered states of consciousness experienced by some individuals. 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). Surprisingly, sleep apnea may exacerbate cardiovascular disease (Sánchez-de-la-Torre, Campos-Rodriguez, & Barbé, 2012). It is relatively easy to wake someone from stage 1 sleep; in fact, people often report that they have not been asleep if they are awoken during stage 1 sleep. Other drugs, including the opioid buprenorphine, have also been used to alleviate symptoms of opiate withdrawal. It may feel like alcohol helps you sleep, but it actually disrupts REM sleep and leads to frequent awakenings. It is indicated that the common hypofrontality (underactivation of frontal brain parts) and cortical activation pattern induced by serotonergic and glutamatergic hallucinogens is due to a common disruption of thalamic gating of sensory and cognitive information.
