It is interesting to consider that while muscles all over the body are paralyzed during sleep, respiration is little affected, except that some muscles in the upper respiratory airways are inhibited during sleep (44). The https:// ensures that you are connecting to the 16. 131. It is usually taken for granted that PGO potentials are essential manifestations for the electrophysiological identification of dreaming activity but such view is not well founded. Revonsuo A. Unable to load your collection due to an error, Unable to load your delegates due to an error. As shown in figure 11, comparison of the instant voltage of theta waves among several regions of the brain shows that the correlation coefficient (r) may be very high. 63. Several authors also quantified the kinds of dreams as related to their sensory content. In humans a dream may be reported and its content can thus be analyzed. 87. The correlation between dream content and the oniric movements was first studied by Aristotle, who identified lip, eye and limb movements and correctly related them to what was being dreamed of. Guazzi M, Baccelli G, Zanchetti A. Carotid body chemoreceptors: physiological role in buffering fall in blood pressure during sleep. 31. The subjects of dreams are broad-ranging and complex, incorporating self-image, fears, insecurities, strengths, grandiose ideas, sexual orientation, desire, jealousy and love". Neuroscience 1997;78:13-38. Brooks DC, Bizzi E. Brain stem electrical activity during deep sleep. Whereas Freud was convinced that dream forgetting was an active function of repression, Hobson, Pace-Schott & Stickgold (2000) attribute the failure to recall a dream to a state-dependent amnesia caused by aminergic demodulation of the sleeping brain (120). Dement WC. (1987) suggested the occurrence of two kinds of eye movements during dreams, one associated to the very dream content, another of reflex nature, that may be involved in those occurring in children and in blind people but such a hypothesis is unlikely to be valid (35). McCarley RW, Nelson JP, Hobson JA. Moruzzi G. The sleep-wakefulness cycle. No wonder that dream recall is impaired in brain-damaged patients (97). MeSH Physiol Behav 1974;12:293-5. Ergebn. Ergebn. 32. There are other definitions of the word dream, too. J Neurophysiol 1946;9:165-71. Hodes R, Dement WC. 34. Psychoanalysis also considers dreams as the expression of repressed wishes; this is undoubtly true as to only a few dreams, whereas several studies reveal, instead, that most dreams are closely related to the events of the previous day, as Aristotle had already demonstrated. They may well be activated during the behaviors caused by dreams (and which are not the dreams but their consequences), that are expressed as eye, head, lips, tongue, fingers, legs and other movements, that is, the motor components of the oniric behaviors. Reticulospinal and reticulobulbar tracts are involved in conveying to the motoneurons the impulses that cause oniric movements. Generally, in humans oniric activity is expressed as eye movements, what is obviously linked to vision as the main human sensory channel. Control of ventilation during sleep. Doneshka & Kehaiyov (1978) reported dreams with striking vestibular sensations. Expt Neurol 1976;53:328-38. 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). Movements of the eyes when the lids are closed. Baldissera F, Cesa-Bianchi MG, Mancia M. Phasic events indicating presynaptic inhibition of primary afferents to the spinal cord during desynchronized sleep. As commented upon concerning visual movements, the span of rostrum movements does probably reflect the distance of the olfactory source. Vertes RP. Sleep 1982;5:169-87. Rothschuch KR. 133. Time course of foslike immunoreactivity associated with cholinergically induced REM sleep. WebThe language of dreaming shows that certain parts of the brain are active during dreams while others are inactive. 128. From a very weak inhibition in early infancy, it goes up rapidly up to 15 years of age, evolving asymptotically from this period on. Lucrce. Sleep 1999;22:409-18. The other is that dreams are caused by forebrain activation by dopamine. Physiol Behav 1972;8:363-71. Aristotle (1), who had carefully observed several animal species while asleep, noticed that movements of several of their body parts were quite similar to those performed by humans during dreaming. and transmitted securely. Sleep 1973;2:36-42. Vertes & Eastman (2000), for instance, believe that the stressful conditions in experiments intended to demonstrate a role of desynchronized sleep and dreaming in consolidation of memory spoil the results (88). This is for sure the most enigmatic issue about dreaming. Bol Inst Est Md Biol Mxico 1962;20:155-64. 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). J Neurosci 1991;11:2804-11. 65. Heart rate decreases down to nearly 150 bpm 1 or 2 seconds following the cessation of eye movements. Brain Mechanism and Perceptual Awareness. Rechtschaffen A, Buchignani C. The visual appearance of dreams. WebAs the foregoing discussion of rival theories of dream function suggests, there are many findings that contradict the idea that dreams have any kind of physiological or Jouvet M. Programmation gntique itrative et sommeil paradoxal. Frequency clearly increases and becomes regular, as compared with the trend before oniric activity. 2009 Nov;10(11):803-13. doi: 10.1038/nrn2716. 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 In: M. C. Hepp-Reymond & G. Marini (eds.) Therefore, desynchronized sleep should be ascribed a homeothermic function (116). Electroencephal Clin Neurophysiol 1955:673-690. NeuroReport 1997;8:3-7. Functional neuroanatomy of human rapid-eye-movement sleep and dreaming. 14. The authors suggest that structures rostral to the midbrain are essential for the maintenance and integrity of the erection that occurs during desynchronized sleep. 49. ", "As to the oviparous creatures, it is obvious that they sleep but it is impossible to state that they dream. Contemporary neuroscientific theories often view dreams as epiphenomena, and many of the proposals for their biological function are contradicted by the phenomenology of dreams themselves. In this review, the neural circuits underlying dreaming and the physiological functions associated with it are summarized. It is not known if such a mechanism does exist in humans; if it exists, what is highly possible, we can reason that it is the activity of the chemoreceptor system that senses pO2 that keeps us alive during desynchronized sleep. Vogel GW, Foulkes D, Trosman H. Ego functions and dreaming during sleep onset. 2020 Nov 12;11:565694. doi: 10.3389/fneur.2020.565694. J Abnorm Psychol 1982;91:433-6. Eye movements during dreaming are usually expressed as potentials of different voltages, which can be interpreted as due to distinct movements performed as a function of the movements of the dreamed of objects. 42. Petersohn D, Schoch S, Brinkmann DR, Thiel G. The human synapsin II gene promoter. Instead, they thought that dreams were not provoked by spirits, ghosts or gods, which took over the mind to express themselves through dreaming. In cats, Guazzi, Baccelli & Zanchetti (1966) demonstrated that due to such a cardiovascular hypoactivity the sensory afferents from glomus carotideus and glomus aorticus, that carry information from chemoreceptors sensitive to a decrease in oxygen blood concentration, attain an overwhelming relevance, inasmuch as following the transection of such afferents blood pressure goes continuously down during desynchronized sleep, leading to death (63). 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. Harvey Lect 1963;58:233-97. Despite such discrepancies, however, during synchronized sleep PRT studies reveal a decrease in global cerebral energy metabolism relative to both waking and desynchronized sleep. 36. Electroencerph Clin Neurophysiol 1964;17:617-29. Gassel MM, Marchiafava PL, Pompeiano O. Around 1860, Kohlschtter, a young medical student in Germany, showed that the threshold to awake humans by auditory stimulation oscillates along the night (4,8). Sleep and dreaming: induction and mediation of REM sleep by cholinergic mechanisms. WebThe 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. 11. Stimulus response theory of dream: The stimulus response theory which existed prior to Freud is based upon the associationistic stimulus response view. This theory stresses the relationship between brain changes during sleep and changes in perceptual efficiency. Some disturbing stimuli force activity into one portion of the cerebral cortex. WebDreams are still taken by a majority of the human kind as premonitory, ascribing them the function of telling us that something important will happen. Gadea-Ciria M. Plasticity of ponto-geniculo-occipital waves during paradoxical sleep after frontal lobe lesions in the cat. Nature 1989;304:111-4. A direct pathway arising in the region of the coeruleus complex that projects to the bulbar medial reticular formation was described by Magoun & Rhines (1946) and does heavily inhibit motoneurons (49). The substrate, physiological mechanism, and function of dreaming have been explained by many scientists from the neurological, psychiatric, psychological, and philosophical perspective. Baust W. Die Phnomenologie des Schlafes. 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. Progr Neurobiol 1984;22:241-88. (eds.) Lovblad KO, Thomas R, Jakod PM, Scammel T, Bassetti C, Griswold M, et al. Hence, experiments with such animals are extremely valuable and thus will be emphasized in the present review. 43. Oswald I. The hypothesis has been recently put forward by Revonsuo (2000) that the function of dreaming is to simulate threatening events, and to rehearse threat perception and threat avoidance (111). The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Physiology and Psychology. Such high values of r may mean that theta waves arrive in such areas almost synchronously, coming from some other sites in the central nervous system. They also argue that even "expensive and cumbersome evoked potential and computer averaging approaches have not helped us to analyze and compare desynchronized sleep physiology with that of waking in an effective way". 27. J Neurophysiol 1938;1:413-30. Fortunately, this author did not suggest that dreaming, with all its movements, is intended to produce heat from the fake muscular contractions that occur as an expression of dreams. Therefore, any neural event, be it running or just thinking, or dreaming, requires a large amount of oxygen, which is carried to the nervous system by the blood through powerful hemodynamic adjustments, such as increase in blood pressure, heart rate and central blood flow (21,25,26). Thanks to the extraordinary possibilities of functional connections that take place in the brain when the "basic circuitries of our personality are programmed", dreams do contribute to shape new solutions for new problems. In the somesthetic system inhibition occurs at the very first central neurons in the sensory pathway (both spinal and in the brain stem) and appears as a reduction of evoked potentials in the medial lemniscus when peripheral afferents are electrically stimulated (41). WebPsychoanalytic theory of dream: Advanced by Freud, the psychoanalytic theory of dream stands as the most valid and fundamental among all the theories of dream. A regular oscillation modulates the amplitude of the potentials. WebThis theory also implies that dreams are not independently functional but rather a coproduct of the sleeping brain, reflecting the dreamers physiological and psychological Afferent transmission in the somesthetic pathways is inhibited during desynchronized sleep (45-47) and may be the main reason of the powerful inhibition of stretch reflexes in desynchronized sleep. Electroencephalogr Clin Neurophysiol 1997;102:125-31. Since memorized information is the basic material to build up dreams, it is understandable that many (but not all) dreams are threatening and emotionally highly charged (111). 22. Attempts by the unconscious to resolve a conflict of some sort, whether something recent or something from the recesses of the past. The neurophysiological mechanisms of the postural and motor events during desynchronized sleep. 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. Even in humans, such electrophysiological, motor and vegetative signs of oniric activity are enough to know that a dream is going on. Nat Rev Neurosci. A comparison of presleep and REM sleep thematic content. Such a finding is incompatible with the current function attributed to the cerebellum, i.e., only correction of movements. Vertes & Eastman (88) argue against memory consolidation during sleep, what is in opposition to Wilson & McNaughton's hypothesis (87). Roussy F, Camirand C, Foulkes D, De Koninck J, Loftis M, Kerr NH. 69. Accessibility Those that are specific to certain behaviors. Villablanca J. Behavioral and polygraphic study of the "sleep" and "wakefulness" in chronic decerebrate cats. 132. doi: 10.1093/nc/nix009. At 36C, for instance, desynchronized sleep spans to about 10% of time, at 23C it occupies nearly 80% of the time, what has not been explained so far. Experimental study. Further developments in neurobiological research, including lesion and brain imaging studies, have established a clearer view of the functional neuroanatomy of REM sleep and dreaming. Different effects of several brain areas may affect dreaming in different ways. Nikolaev E, Kaminska B, Tischmeyer W, Matthies E, Kaczmarek L. Induction of expression of genes encoding transcription factors in the rat brain elicited by behavioral training. The American psychologist Mary Whiton Calkins published in 1893 an important, although entirely unkwnown, article under the title Statistics of Dreams, wherein she introduced the technique of arousing people when they moved parts of the body during sleep and asking them to report their dreams (4,7). Advances in Sleep Research, vol. The motor components are usually weak and poorly expressed movements during a dream, mainly if it occurs during desynchronized sleep; when a dream takes place during synchronized sleep phase I, near wakefulness, not only movements are more faithful to the dream content but also the latter is much more logic. The Neuropsychology of Sleep and Dreaming. Rapid increase of an immediate early gene messenger RNA in hippocampal neurons by synaptic NMDA receptor activation. When the rat moves the head, for example (which may indicate a vestibular dream), heart rate goes up and may be as high as 330 bpm, similar to that occurring during attentive behavior. 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. 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). Much effort was devoted to searching for parallels between physiological aspects of REM sleep and characteristics of associated dreams, with modest results. & Bertini, M. It is interesting that the representation of animals in dreams of infants is quite conspicuous. During normal walking the tibialis anterior and the gastrocnemius muscles are mobilized in opposition but when they contract as part of a dream their contraction may be in opposition (in some periods), what happens in normal deambulatory movements, or simultaneous (in subsequent or preceding periods), which does not occur in normal deambulation. A dream is a conscious experience that occurs during sleep. In rats subjected to early desynchronized sleep deprivation, ejaculation was deeply reduced in adulthood (114,115), what is a profound impairment of a very important instinctive behavior. Brain Res 1985;327:362-6. This organ receives information from the entire body, including the baroreceptors, as shown by Moruzzi (80). Fratelli Bocca Editori, Torino 1899. The most prominent, the activation-synthesis hypothesis, derived its view of dreaming directly from the neurophysiology of REM sleep, in particular the role of the brain stem, and in its original form regarded dreams as not essentially meaningful. According to Mancia (1995), the brain "produces dreams" as "a symbolic process of elaborating, interpreting and reorganizing in narrative sequences all the material accumulated in the memory during waking hours". The PGO potentials are correlates of dreams. 79. 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. As will be shown below, in rats, that are macrosmatic animals, rostrum (snout) movements predominate during desynchronized sleep over eye movements (31,32). C R Soc Biol (Paris) 1938;128:533-9. 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. 6. As pointed 72. Aserinsky E, Kleitman N. Regularly occurring periods of eye motility and concomitant phenomena during sleep. Xerxes, in fact, had discovered an important aspect of dreams but his oracle discarded such an explanation, in favor of the mystic one. 94. However, considering the high prevalence of dreams during this phase it should be more appropriately named oniric phase of sleep. Science 1987;238:797-9. Brain Res 1979;176:233-54. Wehr TA. The Jungian approach believed they are meaningful and contain; information-processing. 111. Raven Press, New york 1981:405-429. Grimm R, Tischmeyer W. Complex patterns of immediate gene induction in rat brain following brightness discrimination training and pseudotraining. When only one side of the reticular formation is also destroyed, the same pattern of recovery does occur; if the other side of the reticular formation is also destroyed after two or three weeks, recovery of wakefulness and desynchronized sleep is even faster than when both sides are lesioned at the same time.

J Biol Chem 1995;270:24361-9. In blind people, whose auditory and somesthetic sensitivity is enhanced, auditory dreams predominate, as expected from their high auditory sensibility. Later, theta waves were also found in rats during both attentive wakefulness and desynchronized sleep (19,30,31,74-76). In: Pompeiano, O. During the past two decades several authors also did quantify the kinds of dreams. As any information consciously identified, a dream triggers a specific behavior, that we call an oniric behavior. Oka T, Iwakiri H, Mori S. Pontine-induced generalized suppression of postural muscle tone in a reflexively standing acute decerebrate cat. Exp Brain Res 1989;74:11-23. Unfortunately, despite the opinion of great scientists of the past, most researchers that deal with sleep and dreaming, probably moved by philosophical, religious prejudice and a faulty reasoning, do not accept the idea that non-human animals do dream. Schmidek WR, Hoshino K, Schmidek M, Timo-Iaria C. Influence of environmental temperature on the sleep-wakefulness cycle in the rat. Web5 Theories on dreaming . News Physiol Sci 1998;13:91-7. WebAbstract. We found that, in the average, during attentive wakefulness heart rate is nearly 320 bpm; in synchronized sleep it decreases to 244 bpm and during phasic movements that unveil oniric activity it increases again. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. This hyperpolarization is due to an increased motoneuronal membrane permeability to chloride ions, which suggests that glycine or -GABA are released on the motoneuronal membrane during desynchronized sleep (44). Does early night REM dream content reliably reflect presleep state of mind? Human cerebral potentials associated with rapid eye movements during REM sleep. The caudalmost portion of this system (then labeled descending hypnogenic cholinergic) comprises the ventral and dorsal Gudden's nuclei, whose stimulation with carbachol triggered sleep in nearly 20 seconds. 75. In Greece dreams were called oneiros, a word that originated the adjective oniric but that meant not exactly what was dreamed about neither the dreaming process, which was not rated as something important, but the phantasmata, i.e. Hernndez-Pen R, Ibarra GC, Morgane PJ, Timo-Iaria C. Limbic cholinergic pathways involved in sleep and emotional behavior. 15. Braun et al. Berlucchi G. Mechanismen von Schlafen und Wachen. Some more recent theories of dreaming emphasize an adaptive function related to emotion and a role in learning and memory consolidation. Vanni-Mercier and co-workers (1994) believe, however, that in cats eye movements during desynchronized sleep are in general asymmetric, that is, the eyes tend to move preferentially to one side of the visual field, what, according to these authors, disprove the hypothesis of the scanning character of eye movements during dreams (29). 29. Neurosci Res 1993;17:127-140. C R S Soc Biol (Paris) 1964;158:99-103. To discuss this issue we will concentrate only on a few hypotheses. Science 1953;118:273-4.

Psychoanalysis considers dreams as an important window to the unconscious world, what makes dream interpretation a crucial factor in psychonalytic diagnosis and treatment. The gamma-alpha loop has been shown to play no role in producing the movements that characterize dreaming. It has, however, been utilized with a great success in sleep studies. Neurosci Conscious.

Dement and P. Passouant (eds.) J Cerebr Blood Flow Metab 1991;11:502-7. 60. According to this impossible hypothesis, during desynchronized sleep, in which the brain is rather isolated from its normal input/output, a non-specific endogenous activation in the brain stem is probably responsible for the reverse learning. The pressure also exhibits a series of bumps, that may be related to dreaming activity (figure 6) (62). 118. Mancia M. One possible function of sleep: to produce dreams. Winson J. Such movements may take the sleeper to fall off the bed. REM sleep and dreaming: towards a theory of protoconsciousness. Desynchronized sleep can be provoked by carbachol infusion in the pontine reticular formation (94). Jouvet M, Michel F, Courjon J. Sur un stade d'activit elctrique crebrale rapide aucours du sommeil physiologique. 38. A related point of view was put forward by Krueger & Obal (1993), who proposed that, on the basis of use-dependent synaptic stabilization, the neuronal assembly not activated during wakefulness will be activated during sleep, to prevent it from atrophy (117). According to Hobson, Pace-Schotter & Stickgold (2000), since image studies show activation of "limbic" and "paralimbic" structures of the forebrain during desynchronized sleep, as compared to wakefulness (120,126-128), emotion may be a primary shaper of dream plots, rather than playing a secondary role plot instigation. The authors concluded that the correlation they found was probably involved in memory consolidation but such coincidence may indicate that during dreaming memorized information is being revoked to integrate a given dreaming pattern. Thus, any study of dreaming also lends itself to psychological scrutiny and clinical application. Miyauchi et al. Foulkes (1982) considered that dreams are so easily forgotten because the brain in desynchronized sleep is in a "reflective state". Noda H, Adey WR. Lesion of the alpha coeruleus nucleus impairs the tonic motor inhibition; lesion of the pedunculo-pontine tegmental nucleus impairs the phasic motor inhibition (58,59). Brainstem Control of Wakefulness and Sleep. Pompeiano O. (eds. Predicting Intention to Participate in Community Physical Activities for Adults with Physical Disabilities. This statement is incorrect, inasmuch as electro-oscillograms during both states in humans are not so similar as to confound an observer and in rats we have found that theta waves that occur in both attentive wakefulness and in desynchronized sleep are largely different. Moruzzi G. Active processes in the brain stem during sleep. Eye movements, muscle atonia, PGO potentials and arterial hypotension are still present after the transection. 89. 74.
