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). When they sleep, fishes keep quiet, with no apparent movements, and then they can be easily fished with a hand.". 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. With developments in understanding of the neurophysiology of REM sleep, new theories of dreaming were proposed. 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). 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. In: The Neuropsychology of Sleep and Dreaming, Antrobus, J. S. & Bertini, M. Rados R, Cartwright RD. 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). J Neurophysiol 1954;17:532-57. 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. Brain Res 1990;517:224-8. Rerum Natura, I et II. 2021 Aug 30;24(2):543. doi: 10.4081/ripppo.2021.543. Eine Methodik der Ableitung localisierter Potentialschwankungen aus subcortikalen Hirngebieten. National Library of Medicine J Neurophysiol 1977;40:284-95. This is an additional fact to point to the activation of other mechanisms capable of producing wakefulness and desynchronized sleep, including dreaming. One is that dreams are generated by the activation of neural activity in the brainstem and its signal transmission to the cortex. Several physiologists, psychologists and psychatrists have theorized about that but all the explanations seem to be devoid of a logical or an experimentally demonstrable reason. Villablanca J. Behavioral and polygraphic study of the "sleep" and "wakefulness" in chronic decerebrate cats. 71. Moruzzi G. Active processes in the brain stem during sleep. In fact, all the phases of wakefulness and sleep, including desynchronized sleep, occur in the cerebellar cortex. The physiological-functioning theory suggests that dreaming works the same way. 85. Instead, they thought that dreams were not provoked by spirits, ghosts or gods, which took over the mind to express themselves through dreaming. Crick F, Mitchison G. The function of dream sleep. Behav Brain Sci 2000;23:1008-9. 40. Moruzzi G. The sleep-wakefulness cycle. Kluger J. As any information consciously identified, a dream triggers a specific behavior, that we call an oniric behavior. Winson J. 18. Electrical potentials recorded from the medial vestibular nuclei precede eye movements by 20 to 30 milliseconds, which points to these nuclei as the last synaptic stations in the pathway that produces eye movements during desynchronized sleep. 45. Inasmuch as all this relevant knowledge is entirely ignored, we hope the present review may help in rescuing it (4). 2019 Oct 22;10:1127. doi: 10.3389/fneur.2019.01127. Neurosc Biobehav Rev 1992;16:372-97. For instance, zif-268 has been shown to induce the expression of a synapse-specific protein, synapsin II (101), and has been linked to the induction of hippocampal long-term potentiation (102,103) and other plasticity phenomena. 80. With developments in understanding of the neurophysiology of REM sleep, new theories of dreaming were proposed. Mirmiran M, Van Someren E. The importance of REM sleep for brain maturation. Problems with Physiological function Theory This does Longitudinal studies. Physiology and Psychology. Arch Ital Biol 1965;103:369-96. (36,37) have recorded contraction of the tympanic muscles (stapedius and tensor tympani) during human sleep. Timo-Iaria C, yamashita R, Hoshino K, Sousa-Melo A. 44. 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. Curr Opin Neurobiol 1992;2:759-63. Much experimental work is needed before a convincing function can be ascribed to the fascinating physiological phenomenon that is dreaming. This organ receives information from the entire body, including the baroreceptors, as shown by Moruzzi (80). Physiological-functioning theor y was supported in a 2009 paper written by J. Allan Recently a more acceptable evidence in favor of the consolidation hypothesis arises from the study of a gene involved in neuronal activation This gene protein, zif-268 (98), binds to a specific DNA molecule present in the promoters of a variety of genes expressed in the nervous system (99) and its up-regulation is thought to initiate a program of gene regulation leading to neuronal plasticity (100). However, considering the high prevalence of dreams during this phase it should be more appropriately named oniric phase of sleep. In some animals, however, a reduction of heart rate and respiration may occur, what also happens during an attentive wakefulness if they are threatened. 67. Aristotle. Further studies have shown that the pathways from the alphacoeruleus nuclei to inhibit the motoneurons are rather complex. 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. In ancient Greece, Socrates, Plato and Aristotle discussed about the meaning of dreams, concluding that the prevailing mistic and mythic concepts about them were incorrect. Science 1994;265:676-9. Such a configuration is subsequently compared to memorized patterns and then, and only then, it can be identified by means of the conscious process. Experimental study. Heart rate decreases down to nearly 150 bpm 1 or 2 seconds following the cessation of eye movements. J Abnorm Psychol 1982;91:433-6. Neurosci Biobehav Rev 1992;16:25-30. J Physiol (London) 1993;461:549-63. 60. This may be related to the presence of pet animals in most families in the Western countries and consequently this "subject" probably becomes the main thought of children. Perachio AA. Vision is our predominant sensory channel, so much so that if we hear a sound we immediately convey the eyes to the source of the sound, trying to identify its origin, even if vision is absent. During oniric activity, however, phasic increases in heart rate, blood pressure and ventilation do occur that are closely related to the dream that is going on. 130. The authors suggest that such a disturbance of reproduction occurs because desynchronized sleep (and consequently dreaming) was prevented to occur normally in infancy but the functional meaning of this interesting phenomenon. 93. Dreams during REM sleep tend to be longer, more vivid, more story-like, and more bizarre than those during NREM sleep. Braz J Med Biol Res 1995;28:385-96. 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. 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). New findings on the neurological organization of dreaming: implications for psychoanalysis. Wehr TA. However, they ignored that the dreams were produced by the brain. For the first time, direct and systematic investigation could be made of such topics as the occurrence, qualities, recollection, and childhood development of dreaming. Nature 1996;383:163-6. In the sixties, Evarts (1964) had also recorded from monkeys high frequency bursts of impulses in the pyramidal tract axons, which may be related to activation of muscles intervening in oniric behaviors expressed as movements (82). Energy conservation theory posits that the main function of sleep is to reduce a person's energy demand during part of the day and night when it is least efficient to hunt for food. 34. 129. Brain Develop (Tokyo) 1992;14:109-20. Penile erection, that also occurs in monkeys, is present during desynchronized (paradoxical or REMsleep) but it is not necessarily linked to erotic dreams. 107. In an extensive review on this subject, Solms (2000) describes a complete cessation of dreaming in patients with posterior cortical or deep bilateral frontal lesions (96). 6. Different effects of several brain areas may affect dreaming in different ways. Unauthorized use of these marks is strictly prohibited. Functional neuroanatomy of human rapid-eye-movement sleep and dreaming. (eds. Does early night REM dream content reliably reflect presleep state of mind? ), Brainstem Mechanisms of Behavior. Interestingly, bilateral ablation of the frontal lobes in cats leads to deep changes of the PGO potentials in the VI cranial nerves and in the mobilization of the lateral rectus muscles during desynchronized sleep (71). Baust W. Die Phnomenologie des Schlafes. Nat Rev Neurosci. 73. Roldan E, Weiss TT. Noda H, Adey WR. Sigmund Freuds theory of dreams suggests that dreams represent unconscious desires, thoughts, wish fulfillment, and motivations. 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. Lovblad KO, Thomas R, Jakod PM, Scammel T, Bassetti C, Griswold M, et al. 3. 51. Miyauchi S, Takino R, Fukuda H, Torii S. Electrophysiological evidence for dreaming. WebDream theories attempt to inform us of our deeper psychological states and shed light on the function of our dreams. Spectrum, New york 1976:411-449. 116. Sleeping and Waking. A powerful defensive behavior, the withdrawal "reflex" (or retraction behavior, as we prefer to call it), is also completely inhibited during this phase of sleep. 43. Geschichte der Physiologie. 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. Jouvet M. Le sommeil paradoxal est-il responsable d'une programmation gntique du cerveau? Head jerky movements may reflect vestibular dreams. Nature, 2002, submitted. 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". 38. 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. It seems that not only humans but also dogs, cows, sheep and goats and the entire family of four-legged viviparous animals do dream. Douglas NJ. From a very weak inhibition in early infancy, it goes up rapidly up to 15 years of age, evolving asymptotically from this period on. Differentiating Oneiric Stupor in Agrypnia Excitata From Dreaming Disorders. Raven Press, New york 1981:405-429. 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. Psychosomat Med 1975;37:147-59. Fenn WO, Hursh JB. 74. Brain Res Mol Brain Res 1996;42:123-7. Ribeiro S, Goyal V, Mello CV, Pavlides C. Brain gene expression during REM sleep depends on prior waking experience. What is the The substrate, physiological mechanism, and function of dreaming have been explained by many scientists from the neurological, psychiatric, psychological, and philosophical perspective. Valle AC, Pellarin L, Timo-Iaria C. Oniric patterns in the rat. 8600 Rockville Pike 86. Krueger JM, Obl F. A neuronal group theory of sleep function. 4. Physiol., Springer-Verlag, Berlin 1972:166-307. 101. 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. 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. No wonder that dream recall is impaired in brain-damaged patients (97). 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. HHS Vulnerability Disclosure, Help Fos-like immunoreactivity was also found in association with cholinergically induced REM sleep (107,108). Bourgin P, Escourrou P, Gaultier C, Adrien J. Electrophysiological manifestations of wakefulness and desynchronized sleep in the rat. 89. NeuroReport 1997;8:3-7. 124. 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. 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. If this hypothesis is correct, it is no surprise that the phases of wakefulness and sleep are expressed in the cerebellar cortex by means of electrophysiological potentials. Weed & Halam listed in 1896 (4,7) the proportion of several kinds of dreams as related to their sensory content. Lucrce. In both instances sleep evolved according to the phases of synchronized and then of desynchronized sleep, during which eye movements always occurred. De Sanctis S. I Sogni e il Sonno. Doctoral thesis, Federal University of So Paulo, 1995. Shiromani PJ, Lai yy, Siegel JM. The cycle of sleep in the rat (preliminary report). Jung R, Kornmller AE. 19. 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. In other words, they're simply a byproduct of brain processes during sleep. 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. In cats, cortical electro-oscillograms are also desynchronized but in the hippocampus theta waves (that will be later described) predominate. J Neurophysiol 1946;9:165-71. At the end of the 19th century several authors published on oniric activity. Some presently available explanations seem science fiction, rather than true science. Arch Gen Psychiat 1966;14:238-48. As a prevailing concept even today, dreams were considered premonitory, messages from the dead and mystical warnings. In decerebrate cats eye movements do occur and are integrated below the midbrain (67,95). The same holds true for animals that live in water, such as fishes, molusks, crustacea and other similar animals; it is impossible to invoke as a proof that they do sleep the shutting of their eyes, inasmuch as they do not have eyelids but it is obvious that they periodically do rest, immobile, what perhaps does explain why at night their predators attack them heavily and devour them. San Diego, 1973. Brain Res 1979;176:233-54. the apparitions. Santos LM, Valle AC, Sameshima K, Silva MTP, Timo-Iaria C. A linear relationship between theta waves frequency and the speed of learning in rats. Although it has not been shown that the alpha-coeruleus nuclei are lesioned in these patients, it is tempting to consider that their lesion underlies such sleep disturbance. 77. Apparently, the main cause of such a reduction of blood pressure and heart rate is the active inhibition of the baroreceptor reflexes during this phase of sleep. University of Chicago Press, Chicago 1963. Many hypotheses have been advanced but so far they do not explain why and what for we do dream. Absence of ponto-geniculo-occipital (PGO) spikes in rats. The previous station of these nuclei is the interpeduncular nucleus, whose stimulation with carbachol caused sleep within nearly 30 seconds. Maquet et al. Those that are specific to certain behaviors. The case against memory consolidation in REM sleep. 83. 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. World Fed Sleep Res Soc Newsletter 1997;5:20-1. In: Klemm, W. R. & Vertes, R. P. Two major theories have been proposed regarding the neural circuits involved in dreaming. Thermoregulation is impaired in desynchronized sleep (64) but it is unlikely that body temperature changes due to dreaming activity, inasmuch as variations of temperature are slow while dreaming is a fast pace phenomenon. Hobson, Pace-Schott & Stickgold (2000) do not take into consideration that a single object or a brief key fact or image occurring in the day preceding a given dream may be enough to trigger an entire dreamed "story" related to it (120). Roffwarg HP, Herman J, Lamstein S. The middle ear muscles: predictability of their phasic action in REM sleep from dream recall. Hippocrates and Alkmaeon, who discovered that the mind is in the brain, not in the heart, knew that dreams were originated in the brain. Doneshka & Kehaiyov (1978) reported dreams with striking vestibular sensations. Please enable it to take advantage of the complete set of features! Brain Res 1982;233:287-98. Arch Ital Biol 1962;100:216-22. Jouvet M. Neurophysiology of the states of sleep. Disclaimer. The result of such conscious identification is a dream. Chaudhuri A. Neural activity mapping with inducible transcription factors. Oka T, Iwakiri H, Mori S. Pontine-induced generalized suppression of postural muscle tone in a reflexively standing acute decerebrate cat. J Cerebr Blood Flow Metab 1991;11:502-7. Changes in neuronal activity in association cortex of the cat in relation to sleep and wakefulness. Careers. Their data do not depart from modern studies of the same kind. 1996 Sep 12;383(6596):163-6. doi: 10.1038/383163a0. The main purpose of experimental decerebration is to study the mechanisms of the fundamental posture, that is, the standing posture. He gives The waking level of aminergic modulation falls to 50% during synchronized sleep and to nearly zero in desynchronized sleep (121,122). Moruzzi G. Sleep and instinctive behavior. 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. The heart rate and breathing quickens, and blood pressure rises. 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. 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. Arch Psychiat Nervenkrankh 1938;109:1-17. There are two kinds of vegetative components: 1. Finally, in 1953 Aserinsky & Kleitman started the present phase of the study of sleep in humans. 14. When a dream has a verbal content the tongue, lips and other facial muscles do contract and if the dream is deambulatory several lower limb muscles do contract, expressing the behavior triggered by the imagined walking. Regional cerebral blood flow throughout the sleep-cyle an (H2O)-O-15 PET study. In the past, most civilizations boasted having wise people who could tell the meaning of dreams if conveniently paid for that, a fancy profession that still has its counterparts in modern nations. Mol Brain Sci 1995;32:211-20. Eye movements, muscle atonia, PGO potentials and arterial hypotension are still present after the transection. 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. Bookshelf Front Neurol. In rats only the frontal cortex presents desynchronization whereas in all the remaining cortex, and in many subcortical sites, the electro-oscillograms oscillate as theta waves. However, we all know that many dreams are not emotional at all. These findings do not necessarily mean that such areas are involved in generating dreaming. 90. Gottesman C, Gandolfo G, Zernicki B. Arch Ital Biol 1965;103:25-44. 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). 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. Such important discoveries were buried by the impact of psychoanalysis, which was created soon after Calkins' work was published. It has, however, been utilized with a great success in sleep studies. 42. WebPhysiological function Theory regular brain stimulation from REM sleep may help develop and preserve neural pathways. While Freud makes many intuitive ), Ermdung, Schlaf un Traum, Fischer Taschenbuch Verlag, Sttutgart 1971:123-172. Interestingly enough, if body temperature in cats subjected to pontomesencephalic transection is lowered, the amount of desynchronized sleep increases. eCollection 2020. Such activation of zif-268, which is likely to be correlated with the effect of learning on desynchronized sleep, was larger in the frontal and hippocampal cortices, where memorization is well known to occur. 1. On the other hand, cells that were silent during the behavioral task did not show the increase in frequency. 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. 55. "Insects are also creatures that do sleep, so much so that they can be seen resting with no movements whatsoever. 57. By measuring the voltage of the potential generated by the rotation it is possible to know if the object is near or far. Sakai K, Sastre JP, Kanamori N, Jouvet M. State-specific neurons in the ponto-medullary reticular formation with special reference to the postural atonia during paradoxical sleep in the cat. Expt Neurol 1976;53:328-38. We suppose, instead, inasmuch as dreams are forgotten if we are not aroused while dreaming or within ten to fifteen minutes immediately after the dream has ceased, that it may well be that dreams are forgotten because the reticular activating system is highly deactivated during desynchronized sleep and thus the memory of the dreams cannot be consolidated (110). 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.
