Moruzzi G. Active processes in the brain stem during sleep. In cats, cortical electro-oscillograms are also desynchronized but in the hippocampus theta waves (that will be later described) predominate. This is specially true as to bees, that at night do interrupt their hum, "even if they are exposed to the light of a lantern". The https:// ensures that you are connecting to the 81. Studi Psicologici e Clinici di un Alienista. Electrical stimulation of the nucleus reticularis pontis oralis evokes bilateral muscle atonia in decerebrate cats (52). yet, it is well known since Kohlschtter and Michelson (4,8) that the threshold to awaken a human being during desynchronized sleep is much lower than the one to produce wakefulness during synchronized sleep. Now, the recent advent of deep neural networks (DNNs) has finally provided the novel conceptual framework within which to understand Hansotia P, Broste S, Ruggles K, Wall R, Friske M. Eye movement patterns in REM sleep. 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. 18. 2022 Nov 3;12(11):1832. doi: 10.3390/jpm12111832. Electroencerph Clin Neurophysiol 1964;17:617-29. 129. Brain Res Mol Brain Res 1996;42:123-7. Karger, Basel, 1997:65-76. 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. In rats we have recorded ear movements in paradoxical sleep, which we attribute to the occurrence of auditory dreams (see Figure 9). 15. 96. Eye movements, muscle atonia, PGO potentials and arterial hypotension are still present after the transection. 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. REM sleep and dreaming: towards a theory of protoconsciousness. Essential manifestations of dreaming are the conscious experience, the electrophysiological, the motor and the vegetative expression of oniric behaviors in humans as well as in other animals. Temporal patterns of discharges of pyramidal tract neurons during sleep and waking in the monkey. Krueger JM, Obl F. A neuronal group theory of sleep function. Stern W, Forbes WN, Morgane PJ. The subjects of dreams are broad-ranging and complex, incorporating self-image, fears, insecurities, strengths, grandiose ideas, sexual orientation, desire, jealousy and love". However, reflex penile erection is facilitated after spinal transection whereas mesencephalic transections significantly increase the latency to its reflex induction, without affecting the percentage of tests eliciting an erectile event. Am J Physiol 1937;118:8-14. If the animal is trying to identify the source of an odor that is located at a large distance, snout movements are expected to span wide angles at low frequencies, whereas when the source is near such movements are expected to span narrow angles, at high frequencies, just as during wakefulness. Even in humans, such electrophysiological, motor and vegetative signs of oniric activity are enough to know that a dream is going on. In fact, we ignore almost completely why we dream. Braz J Med Biol Res 1990;23:617-20. Mirmiran M, Van den Dungen H, Uylings HBM. J Neurophysiol 1946;9:165-71. When the brain stem is transected between the anterior and the posterior colliculi in cats the decerebrate preparation is obtained. In rats bilateral lesion of the midbrain reticular formation is followed by a long lasting state of synchronized sleep, with predominance of phase III (Timo-Iaria, Assumpo & Bernardi, unpublished observations). 6. With Darwin (1965), we are fully convinced that "at least birds and mammals do dream" (6). 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. Valle AC, Pellarin L, Timo-Iaria C. Oniric patterns in the rat. Sleep and dreaming: induction and mediation of REM sleep by cholinergic mechanisms. Heart rate decreases down to nearly 150 bpm 1 or 2 seconds following the cessation of eye movements. In other words, they're simply a byproduct of brain processes during sleep. 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). The command character of theta waves is probably the reason why such potentials occur almost simultaneously in different brain structures. 90. Winson J. In humans, Hansotia and colleagues (34) found in humans, in accordance with our own observations in rats and cats, that oniric eye movements may be directed to one side or the other, not exclusively to one side, as stated by Vanni-Mercier and co-workers (29). Mori S, Matysuyama K, Kohyama J, Kobayashi y, Takakusaki K. Neuronal constituents of postural and locomotor control systems and their interactions in cats. 88. Spectrum, New york 1976:411-449. Neurons from the nucleus reticularis pontis oralis send fibers to nucleus reticularis gigantocellularis in the medulla, a part of which passes through the dorsal tegmental field of the pons, and electrical stimulation of both nuclei also produces inhibition of muscle tone (53,54). Figure 9 illustrates an episode of olfactory and vibrissal movements. McCarley RW, Nelson JP, Hobson JA. Our hypothesis is that the cerebellum is involved in overall corrections of the components of all kinds of behavior, including sleep. The ancient Chinese scientific inquiry tried to understand dreaming but usually also considered them mistically. Physiological-functioning theor y was supported in a 2009 paper written by J. Allan Axons from neurons of the nucleus reticularis gigantocellularis descend along the ventral and ventrolateral funiculi and connect with inhibitory interneurons in the spinal cord (55,56). In: C. Guilleminaut, W. C. Dement and P. Passouant (eds.) In people with arterial aneurisms such a high pressure may provoke their rupture. Baldissera F, Cesa-Bianchi MG, Mancia M. Phasic events indicating presynaptic inhibition of primary afferents to the spinal cord during desynchronized sleep. Baust's data regarding the cat are also evident (38). During wakefulness theta waves consistently exhibit a lesser voltage and are less regular than during desynchronized sleep, what makes it easy to tell wakefulness from desynchronized sleep from the shear inspection of the electro-oscillograms (21,30,31,125). Lucrce. It seems that not only humans but also dogs, cows, sheep and goats and the entire family of four-legged viviparous animals do dream. For the first time, direct and systematic investigation could be made of such topics as the occurrence, qualities, recollection, and childhood development of dreaming. ), Ermdung, Schlaf un Traum, Fischer Taschenbuch Verlag, Sttutgart 1971:123-172. 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. Some more recent theories of dreaming emphasize an adaptive function related to emotion and a role in learning and memory consolidation. 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). Careers. The PGO potentials are correlates of dreams. As mentioned above, Plato, preceding by twenty four centuries one of the dogmas of psychoanalysis, believed that "forbidden" dreams, such as incestuous or criminal dreams, were only a way of doing incestual sex or killing someone without punishment. 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. The dream between neuroscience and psychoanalysis. 1. Physiol Behav 1970;5:402-7. Table 1 shows the results of some of such studies, including our data concerning nearly 2,000 dreaming episodes recorded from rats. In humans it has been shown that not only EEG desynchronization but also increase in vegetative functions, such as heart rate and ventilation (27), accompany mental activity. sharing sensitive information, make sure youre on a federal Crick F, Mitchison G. The function of dream sleep. Xerxes, in fact, had discovered an important aspect of dreams but his oracle discarded such an explanation, in favor of the mystic one. 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. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. 24. 128. 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. This organ receives information from the entire body, including the baroreceptors, as shown by Moruzzi (80). 116. Jouvet M, Michel F, Courjon J. Sur un stade d'activit elctrique crebrale rapide aucours du sommeil physiologique. The Psychology of Dreaming. Expt Neurol 1976;53:328-38. Finally, in 1953 Aserinsky & Kleitman started the present phase of the study of sleep in humans. Rerum Natura, I et II. In rats we found similar potentials in the amygdala as related to olfactory dreams, expressed as rostrum movements (32). 32. 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. The tonic inhibition of motoneurons by circuits in the alphacoeruleus nucleus during desynchronized sleep is mediated by hyperpolarization of their membrane (41-43). Similarly, in rats any kind of sensory stimulation does immediately mobilize sniffing and vibrissal scanning movements. Dement WC. Ribeiro S, Goyal V, Mello CV, Pavlides C. Brain gene expression during REM sleep depends on prior waking experience. Psychoanalysis considers dreams as an important window to the unconscious world, what makes dream interpretation a crucial factor in psychonalytic diagnosis and treatment. & Bertini, M. These interneurons inhibit motoneurons by means of glycinergic synapses (glycine is a powerful inhibitory neurotransmitter), as shown by Soja et al. 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. Brain Res 1967;5:221-35. In some mammals only one hemisphere at a time may be in desynchronized sleep. J Physiol (London) 1993;461:549-63. 22. Braun AR, Balkin TJ, Wesenten NJ, Carson RE, Varga M, Baldwin P, et al. In fact, all the phases of wakefulness and sleep, including desynchronized sleep, occur in the cerebellar cortex. In: Pompeiano, O. Candia et al. 115. Arch Ital Biol 1965;103:25-44. Hobson JA. Buchsbaum MS, Gillin JC, Wu J, Hazlett E, Sicotte N, Dupont RM, Bunney WE. Thus, any study of dreaming also lends itself to psychological scrutiny and clinical application. Simes CA, Valle AC, Timo-Iaria C. Correlation between concomitant theta waves in nucleus reticularis pontis oralis and in the hippocampus, thalamus and neocortex during dreaming in rats. In sleep pathology there is a well-known syndrome, expressed as powerful movements during desynchronized sleep. Inasmuch as dreaming seems to occur in most birds and mammals, it is unlikely that it has no function in the animal organism. When any part of the brain programs a behavior it sends the program to the cerebellum. Motoneuron inhibition is mild in the early post-birth days and increases according to a saturation curve (60). A dream is a succession of images, ideas, emotions, and sensations that occur for the most part involuntarily during certain stages of sleep. Advances in Sleep Research, vol. In fact, it does frequently occur when movements are expressed as high frequency potentials. Sigmund Freuds theory of dreams suggests that dreams represent unconscious desires, thoughts, wish fulfillment, and motivations. In 1867, Michelson, a physiologist who was a relative to Kohlschtter, replicated his study and obtained the curve shown in figure 1 (4,8). 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. 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). Braz J Med Biol Res 1996;29:1645-50. Arch Ital Biol 1962;100:216-22. These authors argue that despite the marked suppression of desynchronized sleep provoked by tricyclic antidepressants neither selective serotonine reuptake inhibitors and mono-amino-oxydase nor learning and memory are disrupted. 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. 3. The waking level of aminergic modulation falls to 50% during synchronized sleep and to nearly zero in desynchronized sleep (121,122). 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. De Sanctis S. I Sogni e il Sonno. 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. Predicting Intention to Participate in Community Physical Activities for Adults with Physical Disabilities. 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). Experimental methodologies permitted investigation of the responsiveness of dreams to external stimulation and the effects of deprivation of REM sleep. 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). Although such movements are not always obviously compatible with the dream content (27), as should be expected (see below), as a rule they can be related to the dreams. 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. 1996 Sep 12;383(6596):163-6. doi: 10.1038/383163a0. Arch Gen Psychiat 1966;14:238-48. 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). 49. Moruzzi G. Action inhibitrice du palocervelet sur les reflexes circulatoires et respiratoires d'origine sino-carotidinne. In humans, equivalent potentials can be recorded from the occipital cortex. During the past two decades several authors also did quantify the kinds of dreams. With the development of scientific technology, many theories of dreaming have been established. Mori D, Shik ML, yagodnitsyn AS. Raven Press, New york 1981:405-429. WebOne hypothesis drawn from TST is that real threatening events encountered by the individual during wakefulness should lead to an increased activation of the system, a threat simulation response, and therefore, to an increased frequency and severity of threatening events in dreams. Behav Brain Res 1995;69:13-22. Frequency clearly increases and becomes regular, as compared with the trend before oniric activity. Plato, despite his logical view of dreams, antecipated by 24 centuries one of the dogmas of psychoanalysis, stating that the dreams with a sexual background, mainly those with an incestuous content, and those in which the dreamer attacked or even killed someone, did, in fact, represent occult wishes that only could be fulfilled without punishment as an oniric experience. The meaning of dreams. Roldan E, Weiss TT. Cole AJ, Saffen DW, Baraban JM, Worley PF. The reason for such vegetative adjustments is obviously that the nervous tissue is metabolically very demanding, so much so that 20% of the inspired oxygen goes to the nervous system. 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). Petersohn D, Schoch S, Brinkmann DR, Thiel G. The human synapsin II gene promoter. Green JD, Arduini A. Hippocampal activity in arousal. Several authors also quantified the kinds of dreams as related to their sensory content. Proc Assoc Res Nerv Ment Dis. In humans, both reflex activities are also deeply inhibited during desynchronized sleep. Much experimental work is needed before a convincing function can be ascribed to the fascinating physiological phenomenon that is dreaming. We spend a lot of time sleeping. Braz J Med Biol Res 1992;5:745-50. Before Hence, experiments with such animals are extremely valuable and thus will be emphasized in the present review. "Insects are also creatures that do sleep, so much so that they can be seen resting with no movements whatsoever. Jouvet M. Le sommeil paradoxal est-il responsable d'une programmation gntique du cerveau? 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. Pontine cholinergic neurons show fos-like immunoreactivity associated with cholinergically induced REM sleep. 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. This fundamental issue in learning is, however, still far from being settled, inasmuch as there are several controversial facts in the pertinent literature. Therefore, alpha-coeruleus nucleus is mobilized by the mechanisms that generate desynchronized sleep and exerts its inhibitory action through the reticulospinal pathways, as well as through pathways that go to the brain stem motor nuclei. Klein M, Michel F, Jouvet M. tude polygraphique du sommeil chez les oiseaux. 44. 61. 47. 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. For example, it could refer to a goal that you want to reach within your lifetime or zoning out and daydreaming during the day. 107. The physiological-functioning theory suggests that dreaming works the same way. Generally, in humans oniric activity is expressed as eye movements, what is obviously linked to vision as the main human sensory channel. J Neurophysiol 1977;40:284-95. 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). Vertes RB, Eastman KE. 136. Movements of the eyes when the lids are closed. Evarts EV. Doneshka P, Kehaiyov A. Jouvet M. The role of monoamines and acetylcholine-containing neurons in the regulation of the sleep-waking cycle. Erlbaum 1992. During REM sleep, several physiological changes also take place. FOIA Physiol Behav 1974;12:293-5. 7. Their data do not depart from modern studies of the same kind. 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. Theta waves, discovered by Jung and Kornmller in 1938 (72), were extensively studied by Green & Arduini (73), who proved they are related to arousal. 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. 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. Those that are common to all behaviors (increase in heart rate, blood pressure, blood flow to the nervous system and muscles, ventilation, pupil diameter and palmar and plantar electrical conductance) and are intended to increase the supply of blood, oxygen, glucose etc. Fenn WO, Hursh JB. 36. (1999) (126,127,129,130). Kluger J. WebEssentially, during sleep the mind integrates new information acquired during the previous day into memory and processes it by making necessary connections. 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.
