physiological function dream theory

Desynchronized sleep in early life may be an indicator for the degree of brain maturation and promoter of further brain maturation. Maquet P, Pters J, Aerts J, Delfiore G, Degueldre C, Luxen A, Franck G. Nature. 34. and transmitted securely. Socrates, Plato, Aristotle and Xenophanes, nearly 2,400 years ago, were opposed to the prevailing view of the phantastikon, that is, mystic apparitions, and to the premonitory character of dreams as their main characteristics. Later, school and work dominate the mental field and the main features in dreams also change accordingly, supporting this hypothesis. Kluger J. J Neurophysiol 1977;40:284-95. The meaning of dreams. The Psychology of Dreaming. From a very weak inhibition in early infancy, it goes up rapidly up to 15 years of age, evolving asymptotically from this period on. If the animal is kept alive by forced feeding and is kept warm, in six days frontal desynchronization and theta waves in the other cortical areas reappear and then not only wakefulness is fully recovered but also desynchronized sleep, including oniric activity. In addition, blood flow velocity in the middle cerebral artery decreases during synchronized sleep whereas in desynchronized sleep it is similar to that occurring in waking (133). This theory is supported by the fact that the body has decreased metabolism by up to 10% during sleep. Regional cerebral glucose metabolic rate in human sleep assessed by positron emission tomography. Behav Brain Res 1995;69:13-22. The discovery of REM sleep kickstarted a flurry of scientific research into the mechanisms of the sleeping brain. Arch Ital Biol 1965;103:369-96. Assoc Psychophysiol Stud Sleep. Such electrophysiological studies demonstrate that the abovementioned sites in the central nervous system are involved in the oniric movements but they do not prove that such structures generate them. The .gov means its official. Hobson JA, Pace-Schott EF, Stickgold R. Dreaming and the brain: toward a cognitive neuroscience of conscious states. The dream between neuroscience and psychoanalysis. WebDream theories developed by Freud suggest that dreams are psychological, revealing hidden urges, for example. Arch Psychiat Nervenkrankh 1938;109:1-17. Does early night REM dream content reliably reflect presleep state of mind? 84. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. Experimental methodologies permitted investigation of the responsiveness of dreams to external stimulation and the effects of deprivation of REM sleep. Considering that desynchronization is predominant all over the cortex in humans and in the frontal cortex of both cats and rats, we consider it to be a phylogenetically more recent functional acquisition. Behav Brain Sci 2000;23:1008-9. Kleitman N. Sleep and Wakefulness. 131. This organ receives information from the entire body, including the baroreceptors, as shown by Moruzzi (80). The site is secure. Since evoking visual reminiscences during wakefulness and the building up of dreams with visual information are dependent on the visual cortex, both facts can be correlated. Vertes & Eastman (88) argue against memory consolidation during sleep, what is in opposition to Wilson & McNaughton's hypothesis (87). 116. Eye movements in born-blinds are probably due to a quite different reason. eCollection 2017. As pointed Plenum Press, 1990. Such patterns mimic oniric eye movements, which may occur in functional coincidence or not with the visual scenes that are dreamed of. Narcolepsy. REM sleep and dreaming: towards a theory of protoconsciousness. Baust W. Die Phnomenologie des Schlafes. Ribeiro S, Goyal V, Mello CV, Pavlides C. Brain gene expression during REM sleep depends on prior waking experience. After transection of the brain stem at the pontomesencephalic transition, rostrally to locus coeruleus, desynchronized sleep still occurs below the transection (10,90-93). Salivary, gastric, enteric, pancreatic and billiary secretion and contraction of the smooth muscle of the gastrointestinal viscera are specific vegetative components of feeding behavior, as well as secretion of luteotropic hormone, increase in cavernous blood pressure and vaginal blood flow and several other endocrine adjustments are part and characteristic of sexual behavior. sharing sensitive information, make sure youre on a federal This allows us to see the irrational as a normal event, while emotional processing and symbolic identities can be explored. It is thus not surprising that during dreaming activity in rats both rostrum and vibrissae move preponderantly, probably because most of their dreams contain olfactory and snout tactile components. However, we still do not know why most motor units are inactivated while a few ones are mobilized, causing real but incoherent and non-efficient movements. The latter are absolutely necessary for any neural activity to occur, inasmuch as the oxygen required by the nervous system amounts to 20% of the total oxygen consumption (near ten times as much as the average of the body as a whole). The vegetative components, that are phasic increases of heart rate, blood pressure, respiration, pupillary diameter, and most probably metabolic adjustments as well, are expressed more consistently during a dream, as they are during attentive wakefulness. Later, the Roman writer Lucretius, the first popularizer of science, in his book De Rerum Natura (1978) credited these Greek philosophers for the discovery of the characteristics of sleep and dreams (2). An important contemporary of these authors, Charles Darwin, in his landmarking book Emotions in Man and Animals, published in 1872 and reedited several times in the twentieth century (6), states that "at least birds and mammals do dream", a concept that still remains unchallenged, despite which most researchers that carry out studies on sleep still hold that dreaming is specifically human. The preferential eye movements direction may be related to the dream content and, perhaps, as such also to hemispheric dominance but it should always be taken into consideration that any movement originated by a dream is always faulty, otherwise we would perform normal behaviors during a dream, what does not happen due to the inhibition of motoneurons. 1. In fact, we ignore almost completely why we dream. Nature 1989;304:111-4. Dement WC. 21. Hernndez-Pen R, Ibarra GC, Morgane PJ, Timo-Iaria C. Limbic cholinergic pathways involved in sleep and emotional behavior. 45. Exptl Neurol 1963;8:93-111. Many studies performed during the eighteenth century confirmed such statement (4,7). However, considering the high prevalence of dreams during this phase it should be more appropriately named oniric phase of sleep. The first oscillation lasts around two hours, when sleep attains its deepest level; the ensuing cycles last less and their depth tends to decrease until arousal finally occurs, a sequence that recent research has fully confirmed. Bol Inst Est Md Biol Mxico 1962;20:155-64. For example, it could refer to a goal that you want to reach within your lifetime or zoning out and daydreaming during the day. 54. Herodotus, in his Histories, the first textbook on History ever written, tells that the Persian King Xerxes dreamed quite often about the war he was about to fight against Athens. 74. Electrophysiologically, it has been shown that the same type of hippocampal cells that are activated during training in a radial maze are also endogenously reactivated during sleep, which accounts for memory consolidation and for a close correlation between dreams and events preceding sleep (87). Human regional cerebral blood flow during rapid eye movement sleep. Moruzzi G. The sleep-wakefulness cycle. Jouvet M, Michel F, Courjon J. Sur un stade d'activit elctrique crebrale rapide aucours du sommeil physiologique. It has, however, been utilized with a great success in sleep studies. Epub 2009 Oct 1. Chase MH, Morales FR. Wallace CS, Withers GS, George VM, Clayton OF, Greenough WT. Some more recent theories of dreaming emphasize an adaptive function related to emotion and a role in learning and memory consolidation. 117. Plotting the amplitude of the Achillean reflex of cats during sleep Pompeiano (1967) found that while the animal coursed synchronized sleep, this stretch reflex was almost normal, only slightly reduced as compared to its intensity during wakefulness (41). In 1944 Obhlmeyer, Brilmayer & Uhlstrung (10) observed that in humans penile erection occurs during sleep at intervals of 85 minutes, which is the average duration of a sleep cycle. 2021 Aug 30;24(2):543. doi: 10.4081/ripppo.2021.543. Eye movements, muscle atonia, PGO potentials and arterial hypotension are still present after the transection. Arch Ital Biol 1962;100:216-22. Ergebn. In nocturnal macrosmatic animals, olfaction is the predominant sensory channel and their vibrissae are usually very long, to detect the presence of objects at relatively large distances. (1997), in their PET studies, found a significant deactivation, in desynchronized sleep, of a large portion of the dorsolateral prefrontal cortex, what was found also by Madsen et al. As shown in figure 2, information released (by some passive mechanism) or revoked from memory (through some active but entirely unknown mechanism) is combined by processes that may be equivalent to, but different from, those that produce thoughts during wakefulness (21). During wakefulness such periods in rats are concomitant with short but complete immobilization, which is well known to occur when a high degree of attention is being directed to some external object. Analysis of the electro-oscillograms yields extremely relevant information that can be correlated with movements and changes in heart rate, blood pressure and respiration. Penile erection, that also occurs in monkeys, is present during desynchronized (paradoxical or REMsleep) but it is not necessarily linked to erotic dreams. This is an additional fact to point to the activation of other mechanisms capable of producing wakefulness and desynchronized sleep, including dreaming. The postynaptic inhibitory control of lumbar motoneurons during the atonia of active sleep: effect of strychnine on motoneuron properties. We spend a lot of time sleeping. The very essence of dreams is, certainly, memorized information. Vanni-Mercier G, Pelisson D, Goffart L, Sakai K, Jouvet M. Eye saccade dynamics during paradoxical sleep in the cat. WebThis theory also implies that dreams are not independently functional but rather a coproduct of the sleeping brain, reflecting the dreamers physiological and psychological In rats, heart rate is clearly accelerated during the periods of oniric activity, expressed as rostrum+vibrissae, eye, head, ear and limb movements. In cats, during movements related to dreams such hyperpolarization is reinforced by presynaptic inhibition of afferents to motoneurons. Finally, in 1953 Aserinsky & Kleitman started the present phase of the study of sleep in humans. Activity of the red nucleus during deep, desynchronized sleep in the unrestrained cat. 115. WebDream theories attempt to inform us of our deeper psychological states and shed light on the function of our dreams. Reactivation of hippocampal ensemble memories during sleep. Mirmiran M. The function of fetal neonatal rapid eye movement sleep. Federal government websites often end in .gov or .mil. However, in the animals subjected to a rich-environment zif-268 increased significantly from synchronized to desynchronized sleep but decreased from wakefulness to synchronized sleep. 72. There are other definitions of the word dream, too. Braz J Med Biol Res 1995;28:385-96. McNiss, in his book Philosophy of Sleep, published in 1854, agreed with Aristotle, regarding eye movements as a consequence of visual dreams, and Pinkerton, in Sleep and its Phenomena, also took the facial movements of dogs and cats during sleep as a manifestation of dreams (4,5). Brain Res 1979;176:233-54. 29. 44. Desynchronized sleep can be provoked by carbachol infusion in the pontine reticular formation (94). Xu Q, Xie H, Zheng D, Wu X, Zhang Y, Li T, Yan T. J Pers Med. The posterior areas affected in this syndrome are the visual areas V3, V3a and V4 (97). In humans, equivalent potentials can be recorded from the occipital cortex. Doricchi F, Violani C. Dream recall in brain-damaged patients: a contribution to the neuropsychology of dreaming through a review of the literature. Ann Rev Psychol 1990;41:557-884. If, as an advantage, in humans such manifestations of dreams can be related to their reported content, in non-human animals it is possible to record with a high degree of accuracy not only the motor and the vegetative manifestations of dremaing but the electro-oscillograms of many central structures as well. Behav Brain Sci 2000;23:877-901. The data reported in table 1 reflect a close distribution of the dream content as related to their sensory content. The command character of theta waves is probably the reason why such potentials occur almost simultaneously in different brain structures. Analysis of psychological theories concerning functions of dreams. The earliest theory to emerge, Freuds psychoanalytic theory, takes an observational approach to identifying the function that dreams serve. Freud theorized that dreams are the result of unfulfilled wishes or desires in the subjects life. 129. However, we all know that many dreams are not emotional at all. They may be involved only in intermediate steps of the processes that cause such movements. 3. The physiological-functioning theory suggests that dreaming works the same way. This author "thus proposes a psychoanalytical model of dreaming, in which dreams constitute a way of representing the individual's inner world with internal objects related with one another and with the self" (135). Consequently, Foulkes concludes that they do not dream but this conclusion is probably incorrect, inasmuch as at this age children have a highly limited narrating capacity and their poor reports about dreams are certainly linked to such a limitation, not their absence. Selective deactivation of the dorsolateral prefrontal cortex has been found in desynchronized sleep. Douglas NJ. By visually examining the amplitude of theta waves in these examples it seems they vary at random but when the instant variation of voltage is plotted as a function of time, a regular variation appears during the phasic movements (figure 10). Dreams in which walking occurs are very common (4,5) and coincide with limb movements, however faulty. Important dream theories are Freud's interpretation of dreams, Brain Res Bull 1992;28:479-84. Braun et al. In humans, both reflex activities are also deeply inhibited during desynchronized sleep. (57). The form and content of dreams is not random but organized and selective: during dreaming, the brain constructs a complex model of the world in which certain types of elements, when compared to waking life, are 95. Researchers working on dream usually do not believe that dreaming may occur in non-human animals, probably due to religious and philosophical reasons but also to a great mistake, i.e., that dreaming is a high level mental activity, such as doing mathematics, but it is not. Heart rate decreases down to nearly 150 bpm 1 or 2 seconds following the cessation of eye movements. The leading theory of dreaming in the early decades of this research was the psychoanalytic, which views dreams as highly meaningful reflections of unconscious mental functioning. 14. Moruzzi G. Active processes in the brain stem during sleep. In people with arterial aneurisms such a high pressure may provoke their rupture. 24. Brain activity during this time keeps us In fact, all the phases of wakefulness and sleep, including desynchronized sleep, occur in the cerebellar cortex. J Neurosci 1991;11:2804-11. 65. Table 1 shows the results of some of such studies, including our data concerning nearly 2,000 dreaming episodes recorded from rats. (1999) (126,127,129,130). The subjects of dreams are broad-ranging and complex, incorporating self-image, fears, insecurities, strengths, grandiose ideas, sexual orientation, desire, jealousy and love". Roffwarg et al. No wonder that dream recall is impaired in brain-damaged patients (97). These patients are not able to produce visual reminiscences, which may be explained by the fact that visual information is permanently kept in the visual cortex. Sleep 1982;5:169-87. 93. In humans a dream may be reported and its content can thus be analyzed. Such hypothesis is grounded on the following steps. Behav Brain Sci 2000;23:867-76. In: Baust, W. 9. Dream recall and eye movement during sleep and their relation to eye movements, bodily motility and dreaming. eCollection 2020. Theta waves, discovered by Jung and Kornmller in 1938 (72), were extensively studied by Green & Arduini (73), who proved they are related to arousal. 13. Another fancy hypothesis is the one that proposes that we dream to forget, in order to delete "unwanted" information by reverse learning or unlearning (118). Brooks DC, Bizzi E. Brain stem electrical activity during deep sleep. Spectrum, New york 1976:411-449. Mancia M. One possible function of sleep: to produce dreams. Before Metabolism during desynchronized sleep tends, in fact, to be equal to or even larger than that of waking (131,132). The lag between tachycardia and eye movements may be related to all the neural processes that are involved in the phases preceding adn succeeding the oniric behavior, including the very identification of the dream content. Spreng LF, Johnson LC, Lubin A. Autonomic correlates of eye movement bursts during state REM sleep. 5. In 1963 we found that cholinergic stimulation of a descending pathway (within Nauta's limbic-mesencephalic system) causes sleep (33). The waking level of aminergic modulation falls to 50% during synchronized sleep and to nearly zero in desynchronized sleep (121,122). It may be more appropriate to explain the latter authors' results by reasoning that dreams are originated in memorized information and are, accordingly, closely related to events occurring before sleep. Brain Mechanism and Perceptual Awareness. 39. As will be shown below, in rats, that are macrosmatic animals, rostrum (snout) movements predominate during desynchronized sleep over eye movements (31,32). J Physiol (London) 1993;461:549-63. Recordings of the electrical activity of the brain, which we will refer to as electro-oscillograms, reveal specific patterns that express the phases of sleep in several central regions of the brain, including the phase during which most oniric activity takes place, the desynchronized or paradoxical sleep. Shiromani PJ, Lai yy, Siegel JM. We propose that the function of dream sleep (more properly rapid-eye movement or REM sleep) is to remove certain undesirable modes of interaction in Frequency clearly increases and becomes regular, as compared with the trend before oniric activity. Also, correlation is high when theta waves in the thalamic reticular nucleus are matched to those occurring in the nucleus reticularis pontis oralis. Despite such facts, some physiologists do not agree that heart rate and blood pressure decrease during desynchronized sleep. J Neurophysiol 1966;29:871-87. 100. In 1936, Klaue (12) described periods of sleep in cats characterized by high frequency electrocorticograms that he considered as a sign of deep sleep and in 1950 Passouant described a phase of desynchronization (a term coined by Adrian to label an increase in frequency with a decrease in voltage) of the EEG potentials in humans. In fact, when the voltage of each theta wave in one site is compared with the voltage in another site it is possible to assess the degree of coincidence or phase shift between the two sites. Arch Ital Biol 1969;107:175-216. Science 1994;265:676-9. WebWhen a person entered rapid eye movement (REM) sleep, it activates circuits within the brain stem. Perspective of Motor Behavior and its Neural Basis. Behav Brain Sci 2000;23:793-842. Rostrum movements in desynchronized sleep as a prevalent manifestation of dreaming activity in Wistar rats. Fortunately, thanks to this peculiar incomplete motoneuron inhibition we are able to record movements occurring in both humans and non-human animals and thus infer the presence of dreams. Therefore, desynchronized sleep should be ascribed a homeothermic function (116). 113. 47. In: Pompeiano, O. Brain Res 1970;19:263-75. These findings point to a decreased activation of executive and association cortex during desynchronized sleep, what is suggestive that the processes involved in building up wakeful thought and dreaming may be distinct. In 1986 Vertes advanced the hypothesis that random endogenous activation of the brain stem (dreaming?) In cats, Thomas & Benoit (18) have found oniric activity during synchronized sleep, similar to what we described in rats as pre-paradoxical sleep (19,20) as intermediate phase. Nature, 2002, submitted. Wiley-Interscience, New york 1990:535-583. Bookshelf J Cerebr Blood Flow Metab 1991;11:502-7. Gottesmann C. Theta rhythm: the brain stem involvement. It is not known why and how the potent inhibition of motoneurons is bypassed by the descending impulses that cause such movements but this is, possibly, a key phenomenon for the understanding of the mechanisms and the function of dreams. Neurosc Biobehav Rev 1992;16:372-97. Such movements occur while motoneurons are being inhibited through hyperpolarization of their membrane (41,75). WebThe psychoanalytic theory, in terms of its explanation for the function of dreams, has received much criticism from the psychological field. This is for sure the most enigmatic issue about dreaming. Vogel GW, Foulkes D, Trosman H. Ego functions and dreaming during sleep onset. 122. C R Soc Biol (Paris) 1938;128:533-9. (1962) clearly demonstrated that in the cat blood diastolic pressure falls deeply to around 60 mmHg, beginning as soon as the electrocorticogram starts to desynchronize. Despite the fact that many studies have found that mental activity during wakefulness differs from that during dreaming, the mechanisms involved in both may differ as to the degree of control over the release and combination of memorized information in wakefulness and in desynchronized sleep. De Sanctis, whose main research on sleep was the incorporation of sensory stimulation into dreams, states in his book that "by measuring the pulse and observing the movements in humans and other animals during sleep it is possible to detect the occurrence of dreaming and sometimes even to guess the dream content". Advances in Sleep Research, vol. Dreams during REM sleep tend to be longer, more vivid, more story-like, and more bizarre than those during NREM sleep. It is most likely an elementary brain activity in homeotherms and thus, if dreaming has a function, it probably plays a similar role in the human brain and in nonhuman brains as well.

Hippocrates and Alkmaeon, who discovered that the mind is in the brain, not in the heart, knew that dreams were originated in the brain. Neuroscience 1997;81:893-926. Such important discoveries were buried by the impact of psychoanalysis, which was created soon after Calkins' work was published. Another change of the electro-oscillograms we disclosed in rats by carefully analyzing their time-course while a dream is on (as well as during attentive wakefulness) is the presence of short periods of desynchronization that interrupt or superimpose on theta waves. The ancient Chinese scientific inquiry tried to understand dreaming but usually also considered them mistically. Although related to the information fluxogram displayed in figure 2 of the present review, Hernandez-Pon's process involves the function of participating in "adaptive waking behavior", which does not seem to have a real meaning (136). Jouvet M. Neurophysiology of the states of sleep. 30. Stimulus response theory of dream: The stimulus response theory which existed prior to Freud is based upon the associationistic stimulus response view.
