With developments in understanding of the neurophysiology of REM sleep, new In some mammals only one hemisphere at a time may be in desynchronized sleep. Cien Cult 1995;47:221-34. Hodes R, Dement WC. In fact, all the phases of wakefulness and sleep, including desynchronized sleep, occur in the cerebellar cortex. Doneshka P, Kehaiyov A. Brain activity during this time keeps us No wonder that dream recall is impaired in brain-damaged patients (97). Petersohn D, Schoch S, Brinkmann DR, Thiel G. The human synapsin II gene promoter. Many hypotheses have been advanced but so far they do not explain why and what for we do dream. 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". Neurosci Conscious. In rats, heart rate is clearly accelerated during the periods of oniric activity, expressed as rostrum+vibrissae, eye, head, ear and limb movements. 59. He properly related such dreams to his concern with that important war. They include facilitation of memory storage, Kuboyama T, Hori A, Sato T, Mikami T, yamaki T, Ueda S. Changes in cerebral blood flow velocity in healthy young men during overnight sleep and while awake.Electroencephalogr Clin Neurophysiol 1997;102:125-31. eCollection 2019. 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). 2019 Oct 22;10:1127. doi: 10.3389/fneur.2019.01127. Karger, Basel, 1997:65-76. Selective deactivation of the dorsolateral prefrontal cortex has been found in desynchronized sleep. Oka T, Iwakiri H, Mori S. Pontine-induced generalized suppression of postural muscle tone in a reflexively standing acute decerebrate cat. Science 1987;238:797-9. 66. While Freud makes many intuitive 134. Interestingly enough, if body temperature in cats subjected to pontomesencephalic transection is lowered, the amount of desynchronized sleep increases. Arch Ital Biol 1965;103:369-96. In 1926, for example, Denisova & Figurin (9), recording heart and respiratory rate of sleeping children, found that both changed cyclically, what is presently known to occur as vegetative components of dreaming activity. 47. 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. San Diego, 1973. Such hypothesis is grounded on the following steps. J Neurophysiol 1964;27:152-71. C R S Soc Biol (Paris) 1964;158:99-103. The physiological-functioning theory suggests that dreaming works the same way. In addition, zif-268 is up-regulated in several novelty or learning behavioral paradigms, including two-way active avoidance (104), brightness discrimination (105), and enriched environment exposure (106). Aristotle. 97. Despite such facts, some physiologists do not agree that heart rate and blood pressure decrease during desynchronized sleep. Forebrain activation in REM sleep: an FDG, PET study. Elsevier Publishing Company Amsterdam, 1962. Arch Gen Psychiat 1966;14:238-48. Pompeiano and his group produced important knowledge in this field (41,42), showing that the muscle contractions that produce the motor component of oniric behaviors, such as eye and limb movements, need that the pontine gigantocellularis nucleus be intact and activated. Electrophysiological manifestations of wakefulness and desynchronized sleep in the rat. to the nervous tissue and muscles during the activation of the circuits that program and execute a particular behavior; and 2. 127. 49. Evarts EV. Shiromani PJ, Winston S, McCarley RW. Chaudhuri A. Neural activity mapping with inducible transcription factors. Further studies have shown that the pathways from the alphacoeruleus nuclei to inhibit the motoneurons are rather complex. 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). Time course of foslike immunoreactivity associated with cholinergically induced REM sleep. Sleep 1999;22:409-18. cognitive development. Accessibility In: M. C. Hepp-Reymond & G. Marini (eds.) Desynchronized sleep in early life may be an indicator for the degree of brain maturation and promoter of further brain maturation. Sigmund Freuds theory of dreams suggests that dreams represent unconscious desires, thoughts, wish fulfillment, and motivations. Vertes RB, Eastman KE. 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). The waking level of aminergic modulation falls to 50% during synchronized sleep and to nearly zero in desynchronized sleep (121,122). Neurosc Biobehav Rev 1992;16:372-97. Thus, any study of dreaming also lends itself to psychological scrutiny and clinical application. 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. WebDream theories developed by Freud suggest that dreams are psychological, revealing hidden urges, for example. Roussy F, Camirand C, Foulkes D, De Koninck J, Loftis M, Kerr NH. The result of such conscious identification is a dream. Kubin L, Davies RO, Pack AI. Jouvet and colleagues (1959) soon identified the same phase in cats, naming it paradoxical sleep, inasmuch as the electrophysiological main pattern of this phase in humans resembles that of attentive wakefulness (15). 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. It has been proposed (120,123,124) that presleep mentation is infrequently incorporated in top dreams and that "naturalistic" day time events rarely enter dream content, but several authors correlated dream content to the previous day events, starting with Aristotle 2,400 years ago and with Calkins in 1893. 39. 56. C R S Soc Biol 1978;172:9-21. Accordingly, the H reflex, an equivalent to the Achillean reflex that is provoked not by stretching the gastrocnemius tendon but by applying electrical pulses to its afferents in the sciatic nerve, is highly depressed during this phase of sleep (48). doi: 10.1093/nc/nix009. & Ajmone-Marsan, C. 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. In non-human animals the report regarding dreams is obviously impossible but, fortunately, a dream can be detected in both humans and other species by analyzing its motor, vegetative and electrophysiological manifestations, as will be described below. 25.

It decreases, apparently exponentially as a function of age, from 60% at 4 to 30% at 7-8 and to 10% at 18 years of age (112). For the first time, direct and systematic investigation could be made of such topics as the occurrence, qualities, recollection, and childhood development of dreaming. In: Pompeiano, O. Nat Rev Neurosci. 92. Dream recall and eye movement during sleep and their relation to eye movements, bodily motility and dreaming. The reason why when we dream we are walking we do not get out of the bed and really walk, or when we dream we are talking to someone we do not really talk, is that neural circuits located in the neighborhood of locus coeruleus, in the pontine tegmentum, inhibit the motoneurons and do not allow the real movements to occur. Studi Psicologici e Clinici di un Alienista. Erlbaum, 1992. Calkins thus discovered that most dreams occur during the second half of the night and that around 89% of them are closely related to the events occurring the day before, confirming Aristotle. The command character of theta waves is probably the reason why such potentials occur almost simultaneously in different brain structures. Takakusaki K, Ohta y, Mori S.

Eye saccade dynamics during paradoxical sleep in the cat. By comparing the program with the peripheral information, that tells it how the behavior is evolving, the cerebellum produces corrections, so that the execution can match the program. As such, this explanation may be interpreted as a way of doing something that we should never be allowed to do without paying for it. Arch Ital Biol 1963;101:648-68. 26.

Autonomic correlates of eye movement bursts during state REM sleep. 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. Guazzi M, Baccelli G, Zanchetti A. Carotid body chemoreceptors: physiological role in buffering fall in blood pressure during sleep. Physiol Behav 1974;12:293-5. 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. In humans a dream may be reported and its content can thus be analyzed. Maquet P, Peters JM, Aerts J, Delfiore G, Degueldre C, Luxen A, et al. Timo-Iaria C, Valle AC. 60. No wonder that most dreams in humans have a visual component, explaining the reason why eye movements occur in any kind of dream, alone or as part of non-visual dreams. Changes in neuronal activity in association cortex of the cat in relation to sleep and wakefulness. Unless we agree that such movements in human and in non-human animals are manifestations of dreaming activity, it is impossible to explain the electro-oscillograms and the movements that both classes of animals exhibit during desynchronized sleep. Brain warning function for REM-sleep. By recording potentials from large ensembles of rat hippocampal neurons related to the body position in space (place cells) during behavioral tasks, Wilson & McNaughton (87) found that neurons that fired together when the animals occupied particular locations in the environment (hence the name place cells) also exhibited an increased tendency to fire together during subsequent sleep, in comparison to sleep episodes preceding the behavioral tasks. Accordingly, they are known as PGO (pontine, occipital cortex and lateral geniculate nucleus) potentials. 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. 117. The oscillation of the sleep depth as cycles, as is well known presently, is quite clear in this figure. Roberts LA, Higgins MJ, O'Shaughnessy CT, Stone TW, Morris BJ. Brain Res Mol Brain Res 1996;42:123-7. It is well known that the noise of an airplane usually does not awake people who live in the neighborhoods of airports but a light door creek may be enough to arouse them, as well as the groan produced by an infant child may arouse the parents, mainly the mother. Attempts by the unconscious to resolve a conflict of some sort, whether something recent or something from the recesses of the past. From the spinal cord Marini (1997) recorded slow (delta) regularly oscillating waves during desynchronized sleep (81), which may be related to activation of spinal neurons during dreaming. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. Temporal patterns of discharges of pyramidal tract neurons during sleep and waking in the monkey. The value of r is as high as 0.9618 when theta waves in the hippocampal CA1 field of one side are matched with those in the nucleus reticularis pontis oralis, what points to a close temporal relationship between theta waves in hippocampus and in the nucleus reticularis pontis oralis. The .gov means its official. Pompeiano O. 31. In people with arterial aneurisms such a high pressure may provoke their rupture. 96. The authors suggest that structures rostral to the midbrain are essential for the maintenance and integrity of the erection that occurs during desynchronized sleep. Sleep and dreaming: induction and mediation of REM sleep by cholinergic mechanisms. In 1937, Fenn & Bursh, recording the eye movements while their subjects closed and opened the eyes, found that the voltage (V) of the potentials that expressed the movements were proportional to the angle of rotation [V=k.2.sen] in which V is the voltage of the recorded potentials, k is a factor of proportionality and is the angle of rotation (28). Arch Ital Biol 1969;107:175-216. 136. Timo-Iaria C, Negro N, Schmidek WR, Rocha TL, Hoshino K. Phases and states of sleep in the rat. Animal experimentation, by making it possible to implant electrodes in any part of the nervous system and to lesion and stimulate (electrically or chemically) also any nucleus or pathway, has been of the utmost relevance for the understanding of the mechanisms causing not only sleep but also the manifestations of dreaming. 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. 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). Unable to load your collection due to an error, Unable to load your delegates due to an error. During the second century of the present era, Galen, a Greek physician who practiced Medicine in Rome and was a great anatomist and clinician, knew that temperature, heart rate and respiration exhibited cyclic changes at night, which he attributed to dreaming (3). Such patterns mimic oniric eye movements, which may occur in functional coincidence or not with the visual scenes that are dreamed of. Lovblad KO, Thomas R, Jakod PM, Scammel T, Bassetti C, Griswold M, et al. Where do dreams come from? 74. 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. Brain Develop 1994;16:81-91. 3. sharing sensitive information, make sure youre on a federal Possible role for the transcription factor zif268/egr-1, polyoma enhancer activator 3, and AP2. Steriade M, McCarley RW. De Sanctis, in 1899, in his book I Sogni, Studi Clinici ed Psicologici di un Alienista (Dreams, Clinical and Psychological Studies of a Psychiatrist), cites no less than 323 articles and books dealing with dreams, which proves that the objective study of dreams did not start during the middle of the 20th century, as is usually taken for granted (4). When any part of the brain programs a behavior it sends the program to the cerebellum. Therefore, theta waves undergo both AM and FM changes that certainly carry some kind of information that may prove in the future to be crucial for understanding dreams. This theory is supported by the fact that the body has decreased metabolism by up to 10% during sleep. McCarley RW, Nelson JP, Hobson JA. Lucrce. Revonsuo A. Brain Mechanism and Perceptual Awareness. WebHe says the function of dreams is that by reproducing difficult or unsolved life situations or experiences, the dream aids towards a solving or resolution of the problems. At the end of the 19th century several authors published on oniric activity. The subjects of dreams are broad-ranging and complex, incorporating self-image, fears, insecurities, strengths, grandiose ideas, sexual orientation, desire, jealousy and love". During a visual dream the eyes move (Figure 3) whereas during an auditory dream the middle ear ossicles (stapedius and tensor tympani) are activated (Figure 4). 85. There are many hypotheses to account for the existence of dreams but it is still a matter of debate why and what for we dream. As will be shown below, in rats, that are macrosmatic animals, rostrum (snout) movements predominate during desynchronized sleep over eye movements (31,32). 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. Buchsbaum MS, Gillin JC, Wu J, Hazlett E, Sicotte N, Dupont RM, Bunney WE. Moruzzi G. Sleep and instinctive behavior. To discuss this issue we will concentrate only on a few hypotheses. MeSH Psychosomat Med 1975;37:147-59. Control of ventilation during sleep. 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. 131. J Neurophysiol 1954;17:532-57. Psychoanalysis considers dreams as an important window to the unconscious world, what makes dream interpretation a crucial factor in psychonalytic diagnosis and treatment. 2017 May 31;2017(1):nix009. Ribeiro S, Goyal V, Mello CV, Pavlides C. Brain gene expression during REM sleep depends on prior waking experience. 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). 64. Those that are specific to certain behaviors. Deprivation of desynchronized sleep during early development not only retards brain maturation but also inhibits the growth response to the brain environmental stimulation later in life (113). 7. 111. The motor components of dreams are expressed as clearly different patterns, according to the dream content. 16. Dreams are still taken by a majority of the human kind as premonitory, ascribing them the function of telling us that something important will happen. 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. Recall of dreams is much greater and the report is much more detailed when one is awakened during desynchronized sleep and the stage I of synchronized sleep, right after alpha waves disappear and are replaced by a lower frequency and lower voltage electro-oscillographic pattern (22,23). Behav Brain Sci 2000;23:877-901. Jouvet M. Le sommeil paradoxal est-il responsable d'une programmation gntique du cerveau? Grimm R, Tischmeyer W. Complex patterns of immediate gene induction in rat brain following brightness discrimination training and pseudotraining. However, during desynchronized sleep it was drastically reduced, being entirely inhibited for most of the time. Science 1953;118:273-4. Wiley-Interscience, New york 1990:535-583. Nature 1989;304:111-4. eCollection 2020. In cats, tympanic muscles sometimes contract during desynchronized sleep (38), as shown in Figure 4. Intermediate state of sleep in the cat. Assoc Psychophysiol Stud Sleep. 40. Not only theta waves do occur in the cerebellar cortex during desynchronized sleep but also spindles and delta waves are found in this organ in synchronized sleep, just as in neocortical areas. In cats, cortical electro-oscillograms are also desynchronized but in the hippocampus theta waves (that will be later described) predominate. Frequency clearly increases and becomes regular, as compared with the trend before oniric activity. Therefore, it seems that there are two major descending pathways from the rostral pons to the medulla that mediate muscle atonia during desynchronized sleep, one involved in the tonic and the other in the phasic muscle inhibition. In cats desynchronized sleep appears also as tonic cortical desynchronization (figure 3) but in the hippocampus, septal area and amygdala theta waves predominate, as in rats and rabbits. A dream is a succession of images, ideas, emotions, and sensations that occur for the most part involuntarily during certain stages of sleep. Van de Castle RL. Despite such discrepancies, however, during synchronized sleep PRT studies reveal a decrease in global cerebral energy metabolism relative to both waking and desynchronized sleep. 2011 Dec;20(4):998-1008. doi: 10.1016/j.concog.2010.10.005. 87. In this review, the neural circuits underlying dreaming and the physiological functions associated with it are summarized. 84.

On the other hand, cells that were silent during the behavioral task did not show the increase in frequency. Muscle atonia during desynchronized sleep is, as stated above, generated in the alpha-coeruleus nucleus and involves both direct and indirect pathways that inhibit the motoneurons. Sakai K, Sastre JP, Salvert D, Touret M, Toyama M, Jouvet M. Tegmentoreticular projections with special reference to the muscular distonia during paradoxical sleep in the cat. However, they ignored that the dreams were produced by the brain. Proposed by Harvard psychiatrists J. Allan Hobson and Robert McCarley in 1977, the theory posits that dreams are your brains attempts to make sense of random patterns of firing neurons while you slumber. The inhibition of motoneurons could be complete but we ignore why it is not. 2021 Aug 30;24(2):543. doi: 10.4081/ripppo.2021.543. Several theories claim that dreaming is a random by-product of REM sleep physiology and that it does not serve any natural function. NeuroReport 1997;8:3-7. Rapid increase of an immediate early gene messenger RNA in hippocampal neurons by synaptic NMDA receptor activation. John Wiley and Sons, New york 1982. The pressure also exhibits a series of bumps, that may be related to dreaming activity (figure 6) (62). Jouvet M. Programmation gntique itrative et sommeil paradoxal. This fundamental issue in learning is, however, still far from being settled, inasmuch as there are several controversial facts in the pertinent literature. Considering that most dreams in rats (31,32) are related to olfaction, not to vision, potentials that resemble PGOs in the amygdala of this animal species should also be taken as signs of dreaming rather than PGOs. 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 No PGO potentials have been found in rats (70). Physiol Behav 1970;5:402-7. 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. Head jerky movements may reflect vestibular dreams. Exptl Neurol 1963;8:93-111. ), Brainstem Mechanisms of Behavior. 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 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. J Physiol (Paris) 1984;79:365-74.
