awakening from sleep is a function of the

during this state, christiana attempts to adopt a nonjudgmental state in which she has awareness of the moment. Normal sleep is divided into non–rapid eye movement (NREM) and rapid eye movement (REM) sleep. And then, you will. . It's a big shift. The good sleepers said, ''I was asleep.'' See the article in its original context from. In other words, everything that it takes to make the molecular, biochemical, cellular oscillation can be found in one cell.'' Our concept of self, on all levels, is dismantled and destroyed piece by piece. Some people -- a tiny minority -- worry that they sleep too much to prosper in these frenetic times. UNDERLYING ALL the intricacies of the human circadian system and all the atemporal elements in modern life that affect our natural periodicity, there is, of course, the greater periodicity of the human organism, the passage from birth to death, to be reckoned with. Like every scientist I talked to, Van Cauter regards as utterly unfounded the recent American fascination with, and embrace of, melatonin as a sleeping potion and all-purpose medicament. Instead, believe your body knows the amount of rest it needs. Enlightenment leaves us lighter, clearer, and aware on a high level. If it had only one copy, it would show a lengthened circadian period of 24.8 hours, ''clearly out of the distribution of normal mice,'' Takahashi said, but still perfectly regular. Eleven young adults had their sleep briefly disturbed following each 2 min of accumulated sleep for 2 consecutive nights in 3 different weeks. Not only did Wehr's subjects ''feel more awake, they were more awake. A protein created by a gene called per (for period) in Drosophila melanogaster, the fruit fly, engenders what Takahashi calls ''a beautiful oscillation in the RNA cycle.'' What was sleep like before television, before electric lights, before the industrial revolution, before agriculture? Being interested in sleep was just a different way of being interested in consciousness. The way we receive It probably has enormous health implications.'' If you don’t sleep, that’s because your body doesn’t need the rest at that moment. (You can now buy melatonin pills even in airport gift shops, thus creating an enormous uncontrolled experiment with a substance that is being used in a test study in the Netherlands as a contraceptive agent.) I became intrigued by the possibility that there might actually be a biological process going on as well. You may even feel achy like you’re getting sick. I could never have predicted what I’d be going through. As Adyashanti tells us, awakening is gritty, intense, and not for the faint of heart. What if the environment is inescapable? ''We decided,'' Wehr told me, ''to take a more general look at what human biology could be like in a longer night -- to reanimate a prehistoric mode. It is only, at most, a few centuries old, a result of our profound conviction that we can control the details of our biological destiny. There are so many cracks in this false reality that it is easy to fall through one if you are … happens whenever, wherever. A Wednesday. REM sleep, and to increase before sleep-to-wake transitions in rats (13). Awakening is a crucial event for the organism. But the penalties for what might be called catastrophic sleep loss are well known. In his opus ''Sleep and Wakefulness,'' first published in 1939, Kleitman defined sleep as ''a periodic temporary cessation or interruption of the waking state, the latter being the prevalent mode of existence for the healthy adult.'' This begins, interestingly, even before the fetal brain can register the differences between light and dark. This mouse plainly lacked any circadian guidance in the absence of environmental cues. Not much is known about the role of prolactin, except in pregnant women. Melatonin is a small molecule, and it slips readily across biological barriers through the placenta. I kept functioning without much sleep. The seasonal fluctuations in conception rates associated with long winter nights, plainly evident before World War I, have essentially disappeared. By Verlyn Klinkenborg. In mammals, brain cooling during NREM sleep is followed by warming during REM sleep, potentially preparing the brain to perform adaptively upon awakening. And having done it, Wehr's subjects remarked that never before had they felt awake. In other words, they spent 14 hours in darkness, from 6 P.M. to 8 A.M., every night for at least a month, just as the aboriginal occupants of Lafayette Park would have done every winter until they died of malaria. He invited self-described good sleepers and self-described bad sleepers to spend the night in the laboratory. His experiments have shown that there is a genetic as well as an environmental limit to the circadian rhythms at work in mammalian physiology. ''Sleep has now been very well described. For example, most parents hold out staying up later as a reward. The electrodes will record the firing rates -- the chemical discharges -- of the individual SCN neurons that happen to lie directly on top of them. About a year ago, when I was right in the thick of my spiritual awakening, I was experiencing a plethora of physical and mental symptoms that made me feel absolutely miserable. measures the speed at which you fall asleep while lying quietly in a dark room. What is it about sleep that's essential for survival? The hour is suppertime, and Carskadon, who looks exhausted, has spent the entire day in the classroom. ''We did a number of experiments showing that the fetus was always in time with the mother. If you get the time kinetics appropriate, then this would be self-sustaining.'' Degus have a number of qualities that make them interesting to sleep researchers and especially to Carskadon. '', ''I repeated the experiment, to see if it was true,'' Mendelson said. It happens just after falling asleep or upon awakening in the morning, in the time between waking and sleep. Some days you will feel over-energized, others you’ll be completely exhausted. There is other evidence about how circadian rhythm is produced at the cellular and genetic levels. Reppert has a picture-window view of the apparatus of molecular biology and of his team of grad students and post-docs. Circadian rhythms attune the human organism to the external environment, but they also coordinate the internal operations of the body. Getting through it requires courage and endurance. The research question that drives Carskadon is all too familiar to parents: Why has this bright, happy child who used to be raring to go at 6 A.M. turned into this morose adolescent you can't get out of bed? Sleep facilitates survival. The average free-running circadian period for the strain of mice in Takahashi's lab is 23.7 hours. Some nights I didn’t sleep at all. I asked Wehr whether any of his subjects had gone crazy lying in the dark during those long nights. These are permanent shifts as our being is literally remade from the energetic level upwards. It rises at 7:19 tomorrow morning. According to the Encyclopedia of Sleep and Dreaming, edited by Mary Carskadon, it is ''the most important hormone for production of casein, the essential protein in human breast milk.'' You can produce a similar effect in a rat by altering its brain, removing the SCN. It could build mighty cities. ''I-94 East,'' the signs read, though the lane I'm in, like the neighboring lanes, is bearing due south. That doesn’t mean it’s true. If you damage the SCN in rats, you change the distribution (but not the quantity) of their sleep. When these are finally released, it unleashes a massive tidal wave of energy in our systems. I was healthy. The wind had risen and waves from Lake Michigan were crashing into the bulwark of the Northwestern campus, just north of Chicago, in a manner that was all too emblematic of the collision between the periodic rhythms of human physiology and the unyielding demands of a 24-hour society. occurrence. It also becomes impossible to imagine that humans have somehow escaped the evolutionary imperative of their environment. Perhaps as we've learned, over time, to sleep a less characteristically mammalian sleep, we've also learned to sleep a less human sleep. As long as sleep was considered little more than an interruption of the waking state, it was treated as a convenient window through which to view the dreaming mind. The homeostatic sleep drive reminds the body to sleep after a certain time and regulates sleep intensity. Call this life on earth 40,000 years ago. Mendelson cited, for my consideration, a perplexing subgroup of insomniacs, a highly unusual example of the trouble humans have in estimating their sleep. But in the early 1970's, it was discovered that in the rodent hypothalamus a small cluster of perhaps 10,000 cells, called the suprachiasmatic nucleus, or SCN, plays a major part in controlling the circadian rhythms of the body, the alternation between biological day and night. After the discovery, in 1929, that electrical activity in the human brain could be traced over the surface of the skull, it became conventional to characterize the stages of sleep in terms of their brain-wave patterns, as recorded in an electroencephalogram, or EEG. Sleep paralysis, which usually happens as you start to fall asleep or wake up, isn’t quite the same as a false awakening. Why do we oscillate? ''The behavioral curtailment of sleep, the deletion of rest,'' Van Cauter says, ''is something that is unbelievably common. It’s also believed enlightenment is something reserved for the elite, the zen masters, and those living in monasteries. They are thorough and nothing is spared scrutiny or transformation. Growth can be challenging, even painful, but once you get to your destination, you’ll see exactly why it was all worthwhile. It But the question of the function of sleep has not been solved. Behind her desk, however, sits the personification of alertness, a handsome chinchilla-like rodent named Prince David, who is a member of the species Octodon degu, the commonest mammal in Chile. Some of them sound ridiculously self-evident (sleep is for rest), but others address the evolutionary origin of sleep, its Darwinian purpose, and in doing so they try to factor in an almost unimaginable number of variables having to do with behavioral adaptation, ecological niches and problems of body size. human sleep resembles that of other mammals to a much greater extent than has been appreciated.'' He says this process took 4-5 years for him. In a scientist, this is a truly amiable trait. Listed below are specific side effects Adyashanti describes, as well as a few other side effects I’ve seen included in several lists of symptoms for spiritual awakenings. Pineal gland and melatonin. It’s not a ringing in That pervasive circadian aspect of behavior -- the precise rhythms of wheel-running, for instance -- we can now track in the firing rhythm of a single cell. It fashions lamps of pitch, animal fat, petroleum, inert gases. There's a switch, and when they run a signal goes to the computer. Just rest and give yourself time. Almost everyone I know complains about sleep, and the refrain is usually ''Not enough.'' Let it be. But basically, when you gave the insomniacs a placebo and woke them and asked, 'Were you awake or asleep?' Rats deprived of REM sleep died in five weeks. 5743 has a shabby, misleadingly obsolescent feel to it. A thread of thought -- the merest particle of wakefulness -- presents itself, and soon the bedside light is on and I'm reading again or lying in the dark, thinking. People don't merely believe they're sleeping less; they are in fact sleeping less -- perhaps as much as one and a half hours less each night than humans did at the beginning of the century -- often because they choose to do so. In general, there was a mental sluggishness I couldn’t escape. This is your body adjusting. While Wehr was studying melatonin secretion, which is, as he says, ''a chemical transducer of nighttime and season,'' he found himself wondering, Have humans preserved a mechanism for perceiving seasonal change, the way animals have? I write things down in journals to keep track of moments I want to preserve, keep a clear schedule, and don’t worry when someone asks for details of a past event that have softened in my mind. The paradox is that as we sleep less and less, we come ever closer to that intermediate level -- half awake, half asleep and totally useless all the time. Rechtschaffen's office is on the third floor of 5743 South Drexel. at the end of the tunnel. If brain warming is the primary function of REM sleep, then it should occur in other animals with similar states. The neuroscience of sleep is the study of the neuroscientific and physiological basis of the nature of sleep and its functions. Because each activity episode and each sleep episode begins slightly earlier than it did the day before, the vertical bars on the activity record of a normal mouse kept in constant darkness will drift to the left as the days pass. '', On the second floor of No. And yet as scientists come closer to understanding the mechanisms of circadian rhythms -- and as sleep deprivation emerges as a major public health issue -- they find themselves still confronting the enigma of sleep's purpose itself. On the Dan Ryan Expressway it is not yet a hyperfine day. Despite this growth, sleep medicine is just now beginning to be taught in medical school, and only within the past year has the American Medical Association recognized sleep medicine as a self-designated specialty. You may have wondered the same, too. It's a very salient phenomenon.''. Some theories on what this is: a sign of ascension as we become more sensitive to high frequencies; the noise of creation as our world shifts to a higher vibration; higher beings, guides, and angels communicating directly with us; downloads of energy from Source to aid in the progress of our awakening; an expansion of our ability to detect the energy frequencies of other beings around us; encouragement of our progress (ringing by the right ear) or a warning (ringing by the left ear). Perhaps you did, too. The literature of sleep positively bristles with descriptions not of slumber itself but of the shapes a moving pen inscribes upon a moving piece of paper: sleep spindles, K-complex waves, alpha waves, theta waves, delta waves -- the impulses of a sleeping brain whose protective shell has been studded with electrical sensors in accordance with the International 10-20 Electrode Placement System. Shift workers especially -- perhaps 20 percent of America's work force -- find themselves in perpetual conflict with the social and environmental cues around them; as a result, they experience higher rates of gastrointestinal and cardiovascular disease, as well as depression and infertility. ''And it was. ''These are people,'' he said, ''who come to the doctor bitterly complaining of insomnia. I’d misspell words constantly (even my own name), the connection between brain and fingers not at all reliable. The body's circadian rhythms are always functioning, but they produce different outputs at different times in a cycle that, left on its own, without light input or behavioral cues, lasts slightly longer than 24 hours. The flux of new energy of our awakening causes highs and lows. ''We see that same pattern,'' she says, ''throughout the rest of adulthood -- what we call a midday trough.'' The shift magnified the importance of the current moment, and everything that’s happened before is now released more easily. Now, my sleep is heavy, deep, and full of wild, vivid dreams (but that’s a whole other story). I had no spiritual mentor by my side to inform me my symptoms were CAUSED by my awakening. Mom's melatonin rhythm is a very precise marker of her circadian system. (A parallel trough, familiar to anyone who has known the despair of early morning, occurs between 1 and 4 A.M., the time when humans are likeliest to mourn credit card debt and to die.) Carskadon's hypothesis is that the entry into adolescence and the dislocations of mood and conduct associated with it mark the maturing of the circadian system. This pattern of divided sleep, separated by rest, is called a bimodal distribution of sleep, and it is typical of the sleep of many mammals living in the wild, which is to say that it is atypical of humans living in modern Western society. Carskadon says: ''It became really evident as I looked at surveys gathered here at Brown that there's a clear delay in the timing of sleep across early adolescence. way my mind works now is clearer, sharper, with more focus and much less noise. He is an affable, intellectually generous man -- dressed in khakis and a polo shirt, he looks as though his impending retirement were less a withdrawal than an embarkation -- but there's something minatory about the approach to his lair. They have trouble judging how long and how well they have slept. The poet Sir Philip Sidney called sleep ''the poor man's wealth, the prisoner's release, the indifferent judge between the high and low.'' Will we go that far to accommodate a sleepless society? What you may not know though, is that our brains don’t function at full capacity for at least the next 30 minutes after abruptly waking up. For each one of these symptoms, I can promise you our resistance to and fear of them only prolongs them. ''Why do we oscillate?'' As the physiological mechanisms of sleep become better understood, doctors are better able to alleviate sleep disorders. Now imagine one such organism with the temerity to light up the night. It asks of these commuters only that they never sleep, too. They are trying to oblige, looking out with bloodshot eyes at brake lights as numerous and motile and waterlogged as cranberries in a bog. Even if light were to disappear for weeks or months at a stretch, the rhythms of biological day and night -- what scientists call circadian rhythms -- would still be produced at precise intervals within the bodies of these organisms. There are a variety of sleep disorders that cause disrupted sleep and increase feelings of tiredness throughout the day and after waking up. ''I see sleeping and waking as an oscillation,'' she said. Enter your email address to subscribe to this blog and receive notifications of new posts by email. So, relax. The rest of the sleep cycle is made up of four non-REM stages, the most important of which, some researchers believe, is slow-wave sleep, also about 20 to 25 percent of a night's sleep.). Like a kid with an 8:30 bedtime in the eternal twilight of summer, I can't quite bear to quit consciousness. But if the mouse is left in darkness for many days, its internal clock is not reset by light, and it adheres to its natural cycle -- ''free-running rhythm,'' as the sleep people say. Sleep-wake homeostasis keeps track of your need for sleep. ''What that means,'' Reppert explained, ''is that the protein that is made in the cell by these genes seems to feed back on its own production. But it was not consolidated sleep, and it was not just sleep. The way we receive information, digest it, and react to it changes entirely. In the last decade, the number of sleep-disorder clinics in the United States has grown to perhaps 1,500, 325 of them voluntarily accredited by the American Sleep Disorders Association. But perhaps there is a simpler, already innate solution to the problem of sleep curtailment, one that depends on our oscillatory nature. - regulates cardiac and respiratory function, maintains consciousness, regulates sleep cycle ... reticular formation - involved in the awakening/sleeping cycle - filters incoming stimuli to discriminate irrelavent background stimuli - controls somatic motor control, cardiovascular control, pain modulation - part of brainstem. It's a puzzle that goes right to the root of our nature. '', Perhaps the task of the next generation of sleeping pills will be to produce the illusion that we have slept well and deeply when in fact we have not. Same answer: Because we oscillate. How we sleep is widely, if implicitly, taken to be an index of things that have little to do with sleep -- emotional balance, competitiveness, sensitivity, toughness. Then they awoke out of REM sleep into another two hours of quiet rest, followed by another four-hour bout of sleep and another two hours of quiet rest before rising at 8 A.M. It has a shape and a hormonal substratum all its own. ''I gave poor sleepers a placebo one night and a sleeping pill the next. Perhaps. Awakening itself prompts us to become healthier by eating better, exercising regularly, and engaging in rigorous self-care. It is on South Drexel Avenue, near the hospital-fortress-complex of the University of Chicago Medical School, where small, jumpy bunches of interns and residents, wearing the white coats given to the professionally sleep-deprived, linger in the courtyard before the university bookstore, which also houses an espresso bar. In my experience, I’ve been able to heal myself in a number of specific ways. But this is the kind of science you can do at home. But we’re not hermetic monks living isolated in caves. This was a phrase I would hear in my head for weeks, and it came to mind again as I sat in an office belonging to Joseph Takahashi, a professor of neurobiology and physiology at Northwestern University and a member of the National Science Foundation Center for Biological Timing. reorganize the way they function and process everything. The white space seemed to be posing a question of its own: What is waking for? Going to bed early is a punishment. ''ALL WAKEFULNESS IS SLEEP deprivation,'' William Dement said to me in mid-September. As the past stretches out behind me, I still know what happened, it’s the details and specifics that can sometimes escape me. You realize that a lot of what you’ve been taught is a lie. The character of Dement's work has changed over the years from analyzing the shape of sleep in the laboratory to focusing public attention on sleep as a vital health issue. I had severe insomnia for months at the beginning of my awakening. It never sleeps. This happens during awakening because our minds completely '', What late-20th-century Americans seem to expect from sleep is simply sleep -- a single, uninterrupted dose of slumber delivered in a sleek package that doesn't get in the way of a busy schedule. The human nervous system is divided into the peripheral and central nervous system (CNS). This was not necessarily news, but it reminded me a little of the moment when you first realize that the eye is not a window, even into the soul, but an organ with its own opacity. It never occurred to me that this was part of awakening until I did research on the ringing sounds and found this listed as a common symptom. 5743, Wallace Mendelson had put it a slightly different way: ''Nobody has the faintest idea what the function of any specific stage of sleep is.''. I also don’t get sick unless it’s clear my body is trying to force me to rest more. If you were to take people off the street, the vast majority would be sleep-deprived.'' If a mouse is exposed to regular 12-hour periods of light and darkness, its activity record usually looks like perfectly vertical alternating bands of white (rest) and black (running) across a 48-hour span. So, I’m writing this post to help anyone else who may be also going through this. Just after Dement's arrival, a graduate student in Kleitman's lab named Eugene Aserinsky discovered, in his sleeping research subjects, rapid eye movement, or REM. When a subject had been asleep for 10 minutes, judging by behavior and brain-wave patterns, Rechtschaffen went into the room, woke the subject and asked him what he had been doing. Adyashanti explains his mind felt like an old fashioned telephone switchboard, removing one plug and manually switching it to another slot. They exemplify the discontinuous logic of sleep, a logic in which the answer to the question ''What is sleep for?'' In Chapter XXXI, Arobin’s persistence leads him to achieve his goal of a sexual relationship with Edna. SLEPT BADLY AGAIN last night. But what it would never, ever elect to do again is turn out the lights and roost when the chickens roost. ''Take respiration,'' Recht schaffen said. I had to figure that out on my own. Every minute splits into local and express, and not a single person in Cook County takes the local. For some it happens all at once, instantly, but this is rare. There are days when I wonder what it feels like to be fully awake. But everything oscillates in biology. Know that the negative facets of these symptoms have since faded away, so there is a light (literally!) Sunrise and nightfall recalibrate the internal clocks of these creatures, so that in winter their biological night is long and in summer it is short. You’ll settle into it and the struggle of transition will end. ''In healthy people,'' Wehr remarked, ''this bimodal pattern of sleep would be called a sleep disorder, although the resemblance to animal sleep confirms its naturalness. Planning is still sharp, it’s the recollection of the past that gets me, because honestly I don’t really care to recollect it. Many small, neatly lettered signs appear on doors and file-cabinet drawers and bookshelves and three-ring-binder hole-punches, signs intended to maintain order in the kingdom of sleep, to insure that the chattels of at least one office in this building remain where they belong. You just have to ride it out. It could foster scientists and doctors whose working lives were spent studying the interactions among light, time and sleep. there is no resisting this. Don't get restless. The problem of sleep curtailment in late-20th-century Western society ''is so big,'' one prominent sleep researcher told me, ''that people just can't digest it. It’s profoundly peaceful and transformative. It ignores what its cells still remember, that light -- even artificial light -- has the power to regulate biological clocks. But as Van Cauter says: ''If people didn't have a problem with sleep, melatonin wouldn't sell. ''We've been able to take these cells,'' Reppert said, speaking of ordinary mouse cells, ''and monitor them the way you would monitor the whole animal, for 42 days. The autonomic nervous system:which regulates functions under subconscious control, such as blood pressure, heart rate, breathing, and digestion… it’s one of the top symptoms of awakening on many lists. Once we surrender to our reality and what we feel, we begin to incorporate the changes into our being. In a most meaningful sense, those are transitional hours. Trust it.
