physiological function dream theory
In other words, they're simply a byproduct of brain processes during sleep. 37. Behav Brain Res 1995;69:13-22. 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. Such movements may take the sleeper to fall off the bed. The other is that dreams are caused 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. 76. Baldissera F, Cesa-Bianchi MG, Mancia M. Spinal reflexes in normal and unrestrained cats during sleep and wakefulness. Moruzzi G. Active processes in the brain stem during sleep. Dement WC. Baldissera F, Cesa-Bianchi MG, Mancia M. Phasic events indicating presynaptic inhibition of primary afferents to the spinal cord during desynchronized sleep. Although it may happen in any sleep phase, it prevails during the desynchronized phase. Brain Develop 1994;16:81-91. 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. 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). In humans the electro-oscillograms during desynchronized sleep are expressed as overall cortical desynchronization, whence the adequacy of the name created by Moruzzi, desynchronized sleep. 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. Visual dreams provoke eye movements. 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. Another change of the electro-oscillograms we disclosed in rats by carefully analyzing their time-course while a dream is on (as well as during attentive wakefulness) is the presence of short periods of desynchronization that interrupt or superimpose on theta waves. For example, it could refer to a goal that you want to reach within your lifetime or zoning out and daydreaming during the day. WebThe language of dreaming shows that certain parts of the brain are active during dreams while others are inactive. Motoneuron inhibition is mild in the early post-birth days and increases according to a saturation curve (60). 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. Behav Brain Sci 2000;23:867-76. Problems with Physiological function Theory This does 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. 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. The other is that dreams are caused by forebrain activation by dopamine. J Biol Chem 1995;270:24361-9. 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. 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. 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. Neurosci Res 1993;17:127-140. He gives There are two kinds of vegetative components: 1. 104. Hodes R, Dement WC. 135. 1996 Sep 12;383(6596):163-6. doi: 10.1038/383163a0. In humans, equivalent potentials can be recorded from the occipital 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. Nature 1989;304:111-4. 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 Gen Psychiat 1966;14:238-48. Science 1966;153:206-8. 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). Around 80 per cent of such motor activity was found to occur during desynchronized sleep, what points to its participation in dreaming activity. Schmidek WR, Hoshino K, Schmidek M, Timo-Iaria C. Influence of environmental temperature on the sleep-wakefulness cycle in the rat. 79. 32. Roffwarg et al. It should be recalled here that, comparing the dream content in humans with events of the previous day, Calkins found in 1876 that nearly 89% of the reported dreams were closely related to such events. 114. Neurosci Conscious. 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. FOIA Heiss W-D, Pawlik G, Herholz K, Wagner R, Weinhard K. Regional cerebral glucose metabolism in man during wakefulness, sleep, and dreaming. This author "thus proposes a psychoanalytical model of dreaming, in which dreams constitute a way of representing the individual's inner world with internal objects related with one another and with the self" (135). 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. 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). Brain Res 1990;517:224-8. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). 107. Hence, experiments with such animals are extremely valuable and thus will be emphasized in the present review. Mirmiran M, Van Someren E. The importance of REM sleep for brain maturation. Desynchronization is the rule, during this phase, in all cortical electro-oscillograms in humans and other primates. government site. Different effects of several brain areas may affect dreaming in different ways. Braz J Med Biol Res 1990;23:617-20. 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). Shiromani PJ, Lai yy, Siegel JM. De Sanctis S. I Sogni e il Sonno. 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. 93. The atonia of myoclonia of active (REM) sleep. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. 27. Intermediate state of sleep in the cat. 16. This organ receives information from the entire body, including the baroreceptors, as shown by Moruzzi (80). Eine Methodik der Ableitung localisierter Potentialschwankungen aus subcortikalen Hirngebieten. Jung R, Kornmller AE. Narcolepsy. It seems that not only humans but also dogs, cows, sheep and goats and the entire family of four-legged viviparous animals do dream. 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. 106. (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). 64. Mol Brain Sci 1995;32:211-20. Gassel MM, Marchiafava PL, Pompeiano O. 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. Mirmiran M. The function of fetal neonatal rapid eye movement sleep. Another hypothesis to account for desynchronized sleep function is that this phase of sleep is programmed to occur when central temperature is low and that it has a thermoregulatory function. 53. 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). Brain activity during this time keeps us functioning and ready to process information when we wake up the next morning! 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. Eye movements in born-blinds are probably due to a quite different reason. For the first time, direct and systematic investigation could be made of such topics as the occurrence, qualities, recollection, and childhood development of dreaming. 120. The vegetative components, that are phasic increases of heart rate, blood pressure, respiration, pupillary diameter, and most probably metabolic adjustments as well, are expressed more consistently during a dream, as they are during attentive wakefulness.

Descending projections from the dorsolateral pontine tegmentum to the paramedian reticular nucleus of the caudal medulla in the cat. 62. On the other hand, cells that were silent during the behavioral task did not show the increase in frequency. J Neurophysiol 1966;29:871-87. 38. C R S Soc Biol 1978;172:9-21. J Sleep Res 1993;2:188-92. 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. Important dream theories are Freud's interpretation of dreams, (eds.) 119. 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). 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). Exploring the neural correlates of dream phenomenology and altered states of consciousness during sleep. In humans a dream may be reported and its content can thus be analyzed. 115. 1. Brainstem mechanisms of slow-wave sleep and REM sleep. Behav Brain Res 1995;69:203-6. 25. 118. During the medieval era in Spain, by then the very cultural center of Europe (probably of the entire world), and mainly in the 13th century, some Muslim Arabs and Jewish rabis, centered in Cordoba rediscovered the Greek literature, that had been concealed by early Christianism, and translated all that important work into Latin, Arabic and Hebraic. Elsevier Publishing Company Amsterdam, 1962. Carcione A, Santonastaso M, Sferruzza F, Riccardi I. Res Psychother. In this review, the neural circuits underlying dreaming and the physiological functions associated with it are summarized. 45. WebIn a nutshell, the theory states that the biological function of dreaming is to stimulate threatening events in order to rehearse the perception of threats and how to go about In rats, heart rate is clearly accelerated during the periods of oniric activity, expressed as rostrum+vibrissae, eye, head, ear and limb movements. 83. 13. Differentiating Oneiric Stupor in Agrypnia Excitata From Dreaming Disorders. Regional cerebral glucose metabolic rate in human sleep assessed by positron emission tomography. 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. 68. Behav Brain Sci 2000;23:877-901. General Learning Press, 1970. 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. 91. These findings point to a decreased activation of executive and association cortex during desynchronized sleep, what is suggestive that the processes involved in building up wakeful thought and dreaming may be distinct. Doneshka & Kehaiyov (1978) reported dreams with striking vestibular sensations. Neuroscience 1997;78:13-38. By visually examining the amplitude of theta waves in these examples it seems they vary at random but when the instant variation of voltage is plotted as a function of time, a regular variation appears during the phasic movements (figure 10). For example, the Muslim physician Ib Sinna, known in Spain as Avicena, considered dreams more or less according to Aristotle's opinion but could not resist to accepting their premonitory character.

In cats, Baust (1971) recorded tachycardia starting 1 or 2 seconds before eye movements appear (38). Learn Mem 1999;6:500-8. The discovery of REM sleep kickstarted a flurry of scientific research into the mechanisms of the sleeping brain. 46. Central activation of autonomic effectors during mental stimulation of motor activity in man. 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.

Figure 6 shows an increase in heart rate from 150 bpm to 180 bpm (the latter is the normal heart rate during resting wakefulness in this species), coinciding with the peak of eye movements. 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. 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). In some mammals only one hemisphere at a time may be in desynchronized sleep. 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. 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).

In addition, blood flow velocity in the middle cerebral artery decreases during synchronized sleep whereas in desynchronized sleep it is similar to that occurring in waking (133). Valle AC, Pellarin L, Timo-Iaria C. Oniric patterns in the rat. As a prevailing concept even today, dreams were considered premonitory, messages from the dead and mystical warnings. 65.

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. This seems to be a highly improbably conception, among other reasons because, as dreaming is concerned, threatening events are as dangerous to the organism as bad news we hear and as crossing a street or watching a movie-film full of violence are as well. Mori D, Shik ML, yagodnitsyn AS. In blind people, whose auditory and somesthetic sensitivity is enhanced, auditory dreams predominate, as expected from their high auditory sensibility. 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. 94. Gottesman C, Gandolfo G, Zernicki B. We spend a lot of time sleeping. J Cerebr Blood Flow Metab 1991;11:502-7. 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. Moruzzi G. Action inhibitrice du palocervelet sur les reflexes circulatoires et respiratoires d'origine sino-carotidinne. 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. 123. Harvey Lect 1963;58:233-97. 132. 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. 29. 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. Kohyama J, Shimomira M, Iwakawa y. Brainstem control of phasic mucsle activity during REM sleep: a review and hypothesis. At the end of the 19th century several authors published on oniric activity. 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. ), Ermdung, Schlaf und Traum, Fischer Taschenbuch Verlag, Sttutgart 1971:173-242. 130. While humans dream around 100 minutes every night, cats exhibit signs of dreaming during nearly 200 minutes per day. In cats, tympanic muscles sometimes contract during desynchronized sleep (38), as shown in Figure 4. Kluger J. Neurosc Res 1993;17:181-202. Their data do not depart from modern studies of the same kind. Sleep patterns during rearing under different environmental conditions in juveline rats. The heart rate and breathing quickens, and blood pressure rises. Careers. 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. Where do dreams come from? 99. Brain Res 1979;176:233-54. Chaudhuri A. Neural activity mapping with inducible transcription factors. It is interesting that the representation of animals in dreams of infants is quite conspicuous. Science 1953;118:273-4. For instance, during desynchronized sleep theta waves, in rats, are highly coherent in nucleus reticularis pontis oralis and in the fronto-parietal cortex, as well as with the hippocampus (78). Interestingly enough, if body temperature in cats subjected to pontomesencephalic transection is lowered, the amount of desynchronized sleep increases. 2021 Aug 30;24(2):543. doi: 10.4081/ripppo.2021.543. Miyauchi et al. Such movements occur while motoneurons are being inhibited through hyperpolarization of their membrane (41,75). Psychoanalysis considers dreams as an important window to the unconscious world, what makes dream interpretation a crucial factor in psychonalytic diagnosis and treatment. 2020 Nov 12;11:565694. doi: 10.3389/fneur.2020.565694. Hippocrates and Alkmaeon, who discovered that the mind is in the brain, not in the heart, knew that dreams were originated in the brain. Exptl Neurol 1963;8:93-111. In normal humans they found that around 20% of the dreams contain a vestibular component (vertigo, sensation of head drop) but in people with a vestibular illness the proportion of such dreams increased to over 70%, as expected from the close relationship between dreams and the events occurring in the previous day (39). 112. Jouvet M. The role of monoamines and acetylcholine-containing neurons in the regulation of the sleep-waking cycle. 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. Our experience with eye movements in rats (30-32) and cats (33) shows, however, that eye movements are sometimes asymmetric but in other occasions they tend to be of the scanning kind. Ponto-geniculo-occipital (PGO) burst neurons: correlative evidence for neuronal generators of PGO waves. Brain Mechanism and Perceptual Awareness. The .gov means its official. 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. We spend a lot of time sleeping. official website and that any information you provide is encrypted Such a finding is incompatible with the current function attributed to the cerebellum, i.e., only correction of movements. The https:// ensures that you are connecting to the During dreaming, however, it is well known that both heart rate and blood pressure undergo short duration increases (as related to the decreased values), which are most likely linked to the oniric behavior. 136. 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).
