These interneurons inhibit motoneurons by means of glycinergic synapses (glycine is a powerful inhibitory neurotransmitter), as shown by Soja et al. 50. Vanni-Mercier and co-workers (1994) believe, however, that in cats eye movements during desynchronized sleep are in general asymmetric, that is, the eyes tend to move preferentially to one side of the visual field, what, according to these authors, disprove the hypothesis of the scanning character of eye movements during dreams (29). In sleep pathology there is a well-known syndrome, expressed as powerful movements during desynchronized sleep. Brain Res 1985;327:362-6. Rerum Natura, I et II. Depression of electrically induced reflexes (H- reflexes) in man during low voltage EEG sleep. 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. With Darwin (1965), we are fully convinced that "at least birds and mammals do dream" (6). 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. The substrate, physiological mechanism, and function of dreaming have been explained by many scientists from the neurological, psychiatric, psychological, and philosophical perspective. 25. 43. Roffwarg HP, Herman J, Lamstein S. The middle ear muscles: predictability of their phasic action in REM sleep from dream recall. Pompeiano O. Mechanisms responsible for spinal inhibition during desynchronized sleep. One is that dreams are generated by the activation of neural activity in the brainstem and its signal transmission to the cortex. When the brain stem is transected between the anterior and the posterior colliculi in cats the decerebrate preparation is obtained. De Sanctis S. I Sogni e il Sonno. While humans dream around 100 minutes every night, cats exhibit signs of dreaming during nearly 200 minutes per day. Braz J Med Biol Res 1996;29:1645-50. 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.

Dreams during REM sleep tend to be longer, more vivid, more story-like, and more bizarre than those during NREM sleep. 13 Loomis AL, Harvey DN, Hobart GA. Distribution of disturbance patterns in the human electroencephalogram, with special reference to sleep. Rapid increase of an immediate early gene messenger RNA in hippocampal neurons by synaptic NMDA receptor activation. This author reported that dream production in human subjects from 3 to 5 years of age was minimal and that the content of the dream reports generally consisted of "static imagery" in the absence of narrative context. Disclaimer. Roffwarg et al. In addition, zif-268 is up-regulated in several novelty or learning behavioral paradigms, including two-way active avoidance (104), brightness discrimination (105), and enriched environment exposure (106). Gassel MM, Marchiafava PL, Pompeiano O. The other is that dreams are caused Table 1 shows the results of some of such studies, including our data concerning nearly 2,000 dreaming episodes recorded from rats. 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. 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. Christy B, Nathans D. DNA binding site of the growth factor-inducible protein Zif268. Proc Assoc Res Nerv Ment Dis. Fos-like immunoreactivity was also found in association with cholinergically induced REM sleep (107,108). 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. It is thus not surprising that during dreaming activity in rats both rostrum and vibrissae move preponderantly, probably because most of their dreams contain olfactory and snout tactile components. 44. No wonder that dream recall is impaired in brain-damaged patients (97). Brain Mechanism and Perceptual Awareness. eCollection 2020. 118. 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. 41. Brainstem control of the events of REM sleep. Brain 1997;120:1173-97. 14. 31. 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. In this review, the neural circuits underlying dreaming and the physiological functions associated with it are summarized. Behav Brain Res 1997;84:109-16. Psychophysiology 1968;4:311-23. Sleep research: pictures from the early years. 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. Oka T, Iwakiri H, Mori S. Pontine-induced generalized suppression of postural muscle tone in a reflexively standing acute decerebrate cat. In fact, it does frequently occur when movements are expressed as high frequency potentials. New findings on the neurological organization of dreaming: implications for psychoanalysis. This neural activity is then interpreted by the brain as an internal activity. Moruzzi's coined the name desynchronized sleep, which we prefer, because in humans desynchronization is the main electrophysiological marker of this phase. In: Baust, W. An analysis of the supraspinal influences acting on motoneurons during sleep in the unrestrained cat. Cole AJ, Saffen DW, Baraban JM, Worley PF. There are two kinds of vegetative components: 1. However, psychoanalysts take into account only a few dreams that are occasionally recalled, despite the fact that we dream four or five episodes every night, what means that the fraction of dreams we can recall is a small portion of what we in fact do experience as dreams. 80. 77. Physiol Behav 1970;5:402-7. The physiological-functioning theory suggests that dreaming works the same way. Maquet P, Peters JM, Aerts J, Delfiore G, Degueldre C, Luxen A, et al. 100.

Cesar Timo-Iaria (in memorian); Angela Cristina do Valle. Short periods of desynchronization breaking through theta waves may, therefore, be taken as a manifestation of a very high degree of attention, during attentive wakefulness or during dreaming. Some authors have not been able to find changes in heart rate and respiration during desynchronized sleep (61) but there are striking demonstrations that blood pressure is reduced (figure 6), attaining values as low as 60 mmHg of systolic pressure; heart rate is also reduced and ventilation decreases (38,62). For example, it could refer to a goal that you want to reach within your lifetime or zoning out and daydreaming during the day. MeSH Brainstem mechanisms of slow-wave sleep and REM sleep. Petersohn D, Schoch S, Brinkmann DR, Thiel G. The human synapsin II gene promoter. During the first half of the twentieth century, despite the heavy influence of psychoanalysis, dreaming was again but sporadically studied scientifically. Life Science 1989;45:1349-56. (eds. It is interesting that the representation of animals in dreams of infants is quite conspicuous. 90. 27. Brainstem Control of Wakefulness and Sleep. (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.

The neurophysiological mechanisms of the postural and motor events during desynchronized sleep. In decerebrate cats eye movements do occur and are integrated below the midbrain (67,95). 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. Theories on the function of REM sleep and dreaming, with which it has a contingent relationship, remain diverse. Physiol., Springer Verlag, Berlin, Heidelberg, New york 1972:1-165. In cats, Baust (1971) recorded tachycardia starting 1 or 2 seconds before eye movements appear (38). Brain Res 2002, submitted. McCarley RW, Nelson JP, Hobson JA. Hippocrates and Alkmaeon, who discovered that the mind is in the brain, not in the heart, knew that dreams were originated in the brain. Several authors also quantified the kinds of dreams as related to their sensory content. These findings do not necessarily mean that such areas are involved in generating dreaming. Penile erection, that also occurs in monkeys, is present during desynchronized (paradoxical or REMsleep) but it is not necessarily linked to erotic dreams. 3. 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. Expt Neurol 1976;53:328-38. 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. 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). Considering that most dreams in rats (31,32) are related to olfaction, not to vision, potentials that resemble PGOs in the amygdala of this animal species should also be taken as signs of dreaming rather than PGOs. Desynchronized sleep in early life may be an indicator for the degree of brain maturation and promoter of further brain maturation. However, human oniric behaviors are also expressed as lips, tongue and facial movements, as well as fingers, toes and whole limbs jerks, as described above. It is likely that even strong stimuli may be ineffective in producing an arousal during sleep if they are trivial, whereas light stimulation containing relevant information may be highly efficient. Candia O, Favale E, Guissani A, Rossi G. Blood pressure during natural sleep and during sleep induced by electrical stimulation of the brain stem reticular formation. Nofzinger EA, Mintun MA, Wiseman MB, Kupfer DJ, Moore Ry. With the development of scientific technology, many theories of dreaming have been established. Arch Ital Biol 1965;103:25-44. 69. J Neurophysiol 1977;40:284-95. PMC 121. Motoneuron inhibition is mild in the early post-birth days and increases according to a saturation curve (60). 28. 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 10. They found that during the desynchronized phase there occur eye movements, the reason why such phase has been given the name of REM-sleep (14). WebExplanation of Physiological function theory This may be true, but it does not explain why we experience meaningful dreams Critical considerations of Physiological function Brain Res 1990;517:224-8.

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). Nature 1989;340:474-6. Clin Chest Med 1985;6:563-75. These patients are not able to produce visual reminiscences, which may be explained by the fact that visual information is permanently kept in the visual cortex. Oswald I. Such a recovery means that other mechanisms are put into action that are able to generate not only wakefulness but desynchronized sleep as well. 13. Rechtschaffen A, Buchignani C. The visual appearance of dreams. Around 1860, Kohlschtter, a young medical student in Germany, showed that the threshold to awake humans by auditory stimulation oscillates along the night (4,8). eCollection 2021 Aug 12. By comparing the program with the peripheral information, that tells it how the behavior is evolving, the cerebellum produces corrections, so that the execution can match the program. Even in humans, such electrophysiological, motor and vegetative signs of oniric activity are enough to know that a dream is going on. Although it may happen in any sleep phase, it prevails during the desynchronized phase. Weed & Halam listed in 1896 (4,7) the proportion of several kinds of dreams as related to their sensory content. 21. J Neurosci 1991;11:2804-11. 104. 20. 96. Braz J Med Biol Res 1995;28:385-96. Mol Brain Res 1996;38:77-84. 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. Vertes & Eastman (2000), for instance, believe that the stressful conditions in experiments intended to demonstrate a role of desynchronized sleep and dreaming in consolidation of memory spoil the results (88). 131. Vanni-Mercier G, Pelisson D, Goffart L, Sakai K, Jouvet M. Eye saccade dynamics during paradoxical sleep in the cat. 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). J Neurophysiol 1964;27:152-71. 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.

The case against memory consolidation in REM sleep. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). A dream is a succession of images, ideas, emotions, and sensations that occur for the most part involuntarily during certain stages of sleep. Doctoral thesis, Federal University of So Paulo, 1995. 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). Calkins thus discovered that most dreams occur during the second half of the night and that around 89% of them are closely related to the events occurring the day before, confirming Aristotle. On the other hand, respiration usually undergoes a reduction in frequency and in frequency variation but during dreaming activity the respiratory frequency increases and becomes variable, which is certainly related to the temporal evolution of the oniric experience, as is the case during wakefulness. In cats, during movements related to dreams such hyperpolarization is reinforced by presynaptic inhibition of afferents to motoneurons. Such patterns mimic oniric eye movements, which may occur in functional coincidence or not with the visual scenes that are dreamed of. 88. 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. 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). 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. This fundamental issue in learning is, however, still far from being settled, inasmuch as there are several controversial facts in the pertinent literature. Differentiating Oneiric Stupor in Agrypnia Excitata From Dreaming Disorders. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. Researchers working on dream usually do not believe that dreaming may occur in non-human animals, probably due to religious and philosophical reasons but also to a great mistake, i.e., that dreaming is a high level mental activity, such as doing mathematics, but it is not. 136. Jouvet M, Michel F, Courjon J. Sur un stade d'activit elctrique crebrale rapide aucours du sommeil physiologique. Arch Gen Psychiat 1966;14:238-48. 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. 120. Ergebn. However, they ignored that the dreams were produced by the brain. doi: 10.1093/nc/nix009. 75. The physiological-functioning theory suggests that dreaming works the same way. Pontine cholinergic neurons show fos-like immunoreactivity associated with cholinergically induced REM sleep. 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). The https:// ensures that you are connecting to the Milbrandt J. The tonic inhibition of motoneurons by circuits in the alphacoeruleus nucleus during desynchronized sleep is mediated by hyperpolarization of their membrane (41-43). (ed. J Ment Nerv Dis 1966;141:623-50. Later, theta waves were also found in rats during both attentive wakefulness and desynchronized sleep (19,30,31,74-76). University of Chicago Press, Chicago & London edition 1985. 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). 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). Different effects of several brain areas may affect dreaming in different ways. Such movements may take the sleeper to fall off the bed. 15. This is for sure the most enigmatic issue about dreaming.

Unauthorized use of these marks is strictly prohibited. Experimental study. Sleep Res 1973;4:65. Exp Brain Res 1989;74:11-23. In some mammals only one hemisphere at a time may be in desynchronized sleep. Recall of dreams is much greater and the report is much more detailed when one is awakened during desynchronized sleep and the stage I of synchronized sleep, right after alpha waves disappear and are replaced by a lower frequency and lower voltage electro-oscillographic pattern (22,23). Considering dreams as hallucinations, Hernndez-Pen (1966) theorized that they are possible because the system responsible for wakefulness is inactivated during sleep, releasing memory tracings which are brought to consciousness. The site is secure. Eye movements in humans predominate because vision is our main sensory channel and our visual memory is overwhelmingly predominant, resulting in preponderance of visual dreams. 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). Brain activity during this time keeps us functioning and ready to process information when we wake up the next morning! Some scientists take the position that dreaming probably has no function. The main purpose of experimental decerebration is to study the mechanisms of the fundamental posture, that is, the standing posture. Soja PJ, Lopez-Rodriguez F, Morales FR, Chase MH. 8600 Rockville Pike He properly related such dreams to his concern with that important war. 5. Sleep 1982;5:169-87. Am J Physiol 1937;118:8-14.

Despite such facts, some physiologists do not agree that heart rate and blood pressure decrease during desynchronized sleep. 63. Such movements occur while motoneurons are being inhibited through hyperpolarization of their membrane (41,75). Neurosc Biobehav Rev 1992;16:372-97. Hence, experiments with such animals are extremely valuable and thus will be emphasized in the present review. It has, however, been utilized with a great success in sleep studies. 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. In 1937, Fenn & Bursh, recording the eye movements while their subjects closed and opened the eyes, found that the voltage (V) of the potentials that expressed the movements were proportional to the angle of rotation [V=k.2.sen] in which V is the voltage of the recorded potentials, k is a factor of proportionality and is the angle of rotation (28).

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. Fortunately, thanks to this peculiar incomplete motoneuron inhibition we are able to record movements occurring in both humans and non-human animals and thus infer the presence of dreams. 47. Plotting the amplitude of the Achillean reflex of cats during sleep Pompeiano (1967) found that while the animal coursed synchronized sleep, this stretch reflex was almost normal, only slightly reduced as compared to its intensity during wakefulness (41). 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. Vogel GW, Foulkes D, Trosman H.

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). (1991) and Lovblad et al. Lovblad KO, Thomas R, Jakod PM, Scammel T, Bassetti C, Griswold M, et al. It would appear that the intense activation of desynchronized sleep must overcome this demodulation and persist into subsequent waking, in order for very vivid dreams to be remembered. The previous station of these nuclei is the interpeduncular nucleus, whose stimulation with carbachol caused sleep within nearly 30 seconds. 86. Kleitman N. Sleep and Wakefulness. 110. Epub 2009 Oct 1. In humans a dream may be reported and its content can thus be analyzed.
