The number of PGO potentials undergoes a high increase after the frontal ablation, which is suggestive of a tonic inhibition of these potentials by the frontal cortex. No PGO potentials have been found in rats (70). Ribeiro S, Goyal V, Mello CV, Pavlides C. Brain gene expression during REM sleep depends on prior waking experience. Oswald I. 67. 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). Nucleus reticularis pontis oralis is thought to contain the generator of theta rhythm (78,79) and is known to send direct efferents to the hippocampus and the cerebellar cortex, where we found theta waves that correlate closely with those in the hippocampus (Valle, Kubo, Iwamoto & Timo-Iaria, in preparation for publication). Penile erection, that also occurs in monkeys, is present during desynchronized (paradoxical or REMsleep) but it is not necessarily linked to erotic dreams. 38. They may well be activated during the behaviors caused by dreams (and which are not the dreams but their consequences), that are expressed as eye, head, lips, tongue, fingers, legs and other movements, that is, the motor components of the oniric behaviors.

Frequency clearly increases and becomes regular, as compared with the trend before oniric activity. 16. Does early night REM dream content reliably reflect presleep state of mind? Another fancy hypothesis is the one that proposes that we dream to forget, in order to delete "unwanted" information by reverse learning or unlearning (118). Braz J Med Biol Res 1990;23:617-20. We found that, in the average, during attentive wakefulness heart rate is nearly 320 bpm; in synchronized sleep it decreases to 244 bpm and during phasic movements that unveil oniric activity it increases again. (ed. J Neurophysiol 1966;29:871-87. Interestingly enough, if body temperature in cats subjected to pontomesencephalic transection is lowered, the amount of desynchronized sleep increases. However, in the animals subjected to a rich-environment zif-268 increased significantly from synchronized to desynchronized sleep but decreased from wakefulness to synchronized sleep. In rats we found similar potentials in the amygdala as related to olfactory dreams, expressed as rostrum movements (32). 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. He properly related such dreams to his concern with that important war. Carcione A, Santonastaso M, Sferruzza F, Riccardi I. Res Psychother. Curr Opin Neurobiol 1992;2:759-63.

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. A theory that has many followers is the one that connects dreams, in particular, desynchronized sleep in general, with memory consolidation. Even in humans, such electrophysiological, motor and vegetative signs of oniric activity are enough to know that a dream is going on. 88. Takakusaki K, Ohta y, Mori S.

Some scientists take the position that dreaming probably has no function. Where do dreams come from? The reinterpretation of dreams: an evolutionary hypothesis of the function of dreaming. The lag between tachycardia and eye movements may be related to all the neural processes that are involved in the phases preceding adn succeeding the oniric behavior, including the very identification of the dream content. 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. Physiol., Springer-Verlag, Berlin 1972:166-307. WebPhysiological function Theory regular brain stimulation from REM sleep may help develop and preserve neural pathways. 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). Maquet et al. Nature, 2002, submitted. In cats, cortical electro-oscillograms are also desynchronized but in the hippocampus theta waves (that will be later described) predominate. 19.

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. Learn Mem 1999;6:500-8. These findings do not necessarily mean that such areas are involved in generating dreaming. Mol Brain Sci 1995;32:211-20. 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. If we dream we are walking, the electromyographic recordings from muscles involved in such behavior show quite clearly that they are not able to produce normal movements. Heart rate decreases down to nearly 150 bpm 1 or 2 seconds following the cessation of eye movements. Contemporary neuroscientific theories often view dreams as epiphenomena, and many of the proposals for their biological function are contradicted by the phenomenology of dreams themselves. 99. Van de Castle RL. 29. However, during desynchronized sleep it was drastically reduced, being entirely inhibited for most of the time. Functional neuroanatomy of human rapid-eye-movement sleep and dreaming. Respiratory frequency decreases during the entire sleep cycle but is phasically activated during dreaming because it is a vegetative function that has to be increased in any behavior, including the oniric ones. 3. 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). Guazzi M, Baccelli G, Zanchetti A. Carotid body chemoreceptors: physiological role in buffering fall in blood pressure during sleep. 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. Modifications of recurrent discharge of the alpha motoneurons during sleep. This site needs JavaScript to work properly. During the first half of the twentieth century, despite the heavy influence of psychoanalysis, dreaming was again but sporadically studied scientifically. Control of ventilation during sleep. Physiol Behav 1974;12:293-5. 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 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. 12. 130. 132. An analysis of the supraspinal influences acting on motoneurons during sleep in the unrestrained cat. A related point of view was put forward by Krueger & Obal (1993), who proposed that, on the basis of use-dependent synaptic stabilization, the neuronal assembly not activated during wakefulness will be activated during sleep, to prevent it from atrophy (117). 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. Bol Inst Est Md Biol Mxico 1962;20:155-64. Brain Develop 1994;16:81-91. As any neural information, it has to be analyzed, so that the nervous impulses, which carry it be decoded and integrated as a specific neural configuration, that contains all the information released (or revoked) from the mnemonic archives. 121. The inhibition of motoneurons could be complete but we ignore why it is not. 6. Xerxes, in fact, had discovered an important aspect of dreams but his oracle discarded such an explanation, in favor of the mystic one. Noda H, Adey WR. J Neurophysiol 1964;27:152-71. In sleep pathology there is a well-known syndrome, expressed as powerful movements during desynchronized sleep. Pompeiano O. Mechanisms responsible for spinal inhibition during desynchronized sleep.

The narrower is the angle of rotation, the lower is the recorded potential, which happens when attention is being directed to a very small part of the object or when the object is very near. It is well known that during desynchronized sleep the pupil undergoes an increase in diameter (midriasis), which is not produced by direct sympathetic activation but rather to parasympathetic inactivation, that overcomes the tonic pupillary constrictor activity of the parasympathetic system during synchronized sleep. When any part of the brain programs a behavior it sends the program to the cerebellum. (eds.) Aserinsky E, Kleitman N. Regularly occurring periods of eye motility and concomitant phenomena during sleep. Movements of the eyes when the lids are closed. Gardner Jr R, Grossman WI, Roffwarg HP, Weiner H.

Time course of foslike immunoreactivity associated with cholinergically induced REM sleep. In more recent years several approaches confirmed these findings (89). 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 73. 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. 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. 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. eCollection 2020. 35. Shiromani PJ, Winston S, McCarley RW. 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. 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). 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). Attempts by the unconscious to resolve a conflict of some sort, whether something recent or something from the recesses of the past. 106. (1962) clearly demonstrated that in the cat blood diastolic pressure falls deeply to around 60 mmHg, beginning as soon as the electrocorticogram starts to desynchronize. By measuring the voltage of the potential generated by the rotation it is possible to know if the object is near or far. Later research argues that dreams are physiological, beginning with random electrical impulses deep within the brain stem. This organ receives information from the entire body, including the baroreceptors, as shown by Moruzzi (80). 5. Behav Brain Sci 2000;23:1008-9. Solms M. Dreaming and REM sleep are controlled by different brain mechanisms. The heart rate and breathing quickens, and blood pressure rises. Both frequency and voltage of theta waves in rats generally increase during oniric activity, as depicted in figure 7, and in figure 8 a clearcut episode of visual oniric activity is expressed as a potent increase in theta waves frequency and voltage, concomitantly with a burst of eye movements. Brain Res 1985;327:362-6. Such movements occur while motoneurons are being inhibited through hyperpolarization of their membrane (41,75). Mol Brain Res 1996;38:77-84. 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. While the how and why of dreaming may be explored using physiological and biological methods, dreaming is also a subjective experience involving a form of mentation that can offer representations of an individual's internal world. Pompeiano O. In: C. Guilleminaut, W. C. Dement and P. Passouant (eds.) Douglas NJ. Motoneuron inhibition is mild in the early post-birth days and increases according to a saturation curve (60). In: The Neuropsychology of Sleep and Dreaming, Antrobus, J. S. & Bertini, M. Braun et al. WebExplanation of Physiological function theory This may be true, but it does not explain why we experience meaningful dreams Critical considerations of Physiological function 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". 14. Editor-translator: Gallop, D., Aris & Phillips Ltd., Warminster, England 1991. (36,37) have recorded contraction of the tympanic muscles (stapedius and tensor tympani) during human sleep.

Inasmuch as all this relevant knowledge is entirely ignored, we hope the present review may help in rescuing it (4). Behav Brain Res 1995;69:13-22. Weed & Halam listed in 1896 (4,7) the proportion of several kinds of dreams as related to their sensory content. 131. In fact, all the phases of wakefulness and sleep, including desynchronized sleep, occur in the cerebellar cortex. 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. 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. In both instances sleep evolved according to the phases of synchronized and then of desynchronized sleep, during which eye movements always occurred. John Wiley and Sons, New york 1982. Gassel MM, Marchiafava PL, Pompeiano O. Darwin C. The Expression of Emotions in Man and Animals. Mori D, Shik ML, yagodnitsyn AS. C R Soc Biol (Paris) 1959;153:1024-8. 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. The subjects of dreams are broad-ranging and complex, incorporating self-image, fears, insecurities, strengths, grandiose ideas, sexual orientation, desire, jealousy and love". 49. 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. (1999) (126,127,129,130). Despite such facts, some physiologists do not agree that heart rate and blood pressure decrease during desynchronized sleep. In this review, the neural circuits underlying dreaming and the physiological functions associated with it are summarized. Baldissera F, Cesa-Bianchi MG, Mancia M. Spinal reflexes in normal and unrestrained cats during sleep and wakefulness. 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). Buchsbaum MS, Gillin JC, Wu J, Hazlett E, Sicotte N, Dupont RM, Bunney WE. 113. (57). Despite several demonstrations that this hypothesis is correct, a few argue against such a view. 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. 111. In blind people, whose auditory and somesthetic sensitivity is enhanced, auditory dreams predominate, as expected from their high auditory sensibility. According to this author, in children at the age of two, when the hippocampus, which is still in the process of development at birth, becomes functional, REM sleep takes on its interpretive memory function (134). The postynaptic inhibitory control of lumbar motoneurons during the atonia of active sleep: effect of strychnine on motoneuron properties. 102. ", "As to the oviparous creatures, it is obvious that they sleep but it is impossible to state that they dream. Christy B, Nathans D. DNA binding site of the growth factor-inducible protein Zif268. We hypothetize that theta waves are commanding signals that recruit in due sequence the circuits that generate wakefulness and desynchronized sleep and their components; their frequency and voltage generally increase in parallel with heart rate and intensity of movements (Valle & Timo-Iaria, unpublished results). 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. A regular oscillation modulates the amplitude of the potentials. Moruzzi G. Action inhibitrice du palocervelet sur les reflexes circulatoires et respiratoires d'origine sino-carotidinne. Xu Q, Xie H, Zheng D, Wu X, Zhang Y, Li T, Yan T. J Pers Med. Decety J, Jeannerod M, Durozard DR, Baveal J. 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). Arch Ital Biol 1962;100:216-22. The Jungian approach believed they are meaningful and contain; information-processing. 43. An important contemporary of these authors, Charles Darwin, in his landmarking book Emotions in Man and Animals, published in 1872 and reedited several times in the twentieth century (6), states that "at least birds and mammals do dream", a concept that still remains unchallenged, despite which most researchers that carry out studies on sleep still hold that dreaming is specifically human. The gamma-alpha loop has been shown to play no role in producing the movements that characterize dreaming. 119. Jouvet M. Neurophysiology of the states of sleep. Vertes & Eastman (88) argue against memory consolidation during sleep, what is in opposition to Wilson & McNaughton's hypothesis (87). Physiol Behav 1972;8:363-71. 36. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. Around 80 per cent of such motor activity was found to occur during desynchronized sleep, what points to its participation in dreaming activity. Valle AC. Neuroscience 1997;81:893-926. The previous station of these nuclei is the interpeduncular nucleus, whose stimulation with carbachol caused sleep within nearly 30 seconds. Cole AJ, Saffen DW, Baraban JM, Worley PF. Berlucchi G. Mechanismen von Schlafen und Wachen. When a dream is a nightmare, both motor and vegetative events may be very intense. The substrate, physiological mechanism, and function of dreaming have been explained by many scientists from the neurological, psychiatric, psychological, and philosophical perspective. 48. The neurophysiological mechanisms of the postural and motor events during desynchronized sleep. 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). Kahn D, Pace-Schott EF, Hobson JA. 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. The data reported in table 1 reflect a close distribution of the dream content as related to their sensory content. Jouvet M, Michel F, Courjon J. Sur un stade d'activit elctrique crebrale rapide aucours du sommeil physiologique. Usually such increases in blood pressure are not enough to lead it to attain normal levels but during a nightmare blood pressure may go up to 200 mmHg. 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. On the functional role of consciousness. Moruzzi G. Active processes in the brain stem during sleep. Gottesmann C. Theta rhythm: the brain stem involvement. Shiromani PJ, Lai yy, Siegel JM. Jouvet (12,119), one of the most important researchers on sleep, suggests that dreaming is "a guardian and programmer of the hereditary part of our personality" and as such it plays a role in our general behavior. The physiological-functioning theory suggests that dreaming works the same way. 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. Role of pontine tegmentum for locomotor control in mesencephalic cat. Cien Cult 1995;47:221-34. The other is that dreams are caused by forebrain activation by dopamine. Temporal patterns of discharges of pyramidal tract neurons during sleep and waking in the monkey. In fact, it does frequently occur when movements are expressed as high frequency potentials. Important dream theories are Freud's interpretation of dreams, Now, the recent advent of deep neural networks (DNNs) has finally provided the novel conceptual framework within which to understand Rechtschaffen A, Buchignani C. The visual appearance of dreams. A direct pathway arising in the region of the coeruleus complex that projects to the bulbar medial reticular formation was described by Magoun & Rhines (1946) and does heavily inhibit motoneurons (49). As pointed 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). There are two kinds of vegetative components: 1. Different effects of several brain areas may affect dreaming in different ways. 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. The site is secure. Esquirol, one of the French psychiatrists who started the revolution that changed the ancient (an cruel) view of the mental diseases, spent several hours at night observing how his patients behaved during sleep and concluded that their movements while asleep were related to their dreams, just as Aristotle had found long ago. Brain Res 1970;19:263-75. 26. 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. 77. 71. Wiley-Interscience, New york 1990:535-583. Phenomenal dream content, however, is not as disorganized as such views imply. 45. C R S Soc Biol (Paris) 1964;158:99-103. Nature 1996;383:163-6.

MeSH 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). Changes in hippocampal gene expression associated with the induction of long-term potentiation. 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).
