physiological function dream theory

Problems with Physiological function Theory This does 4. 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. The dream between neuroscience and psychoanalysis. 81. 79. Exptl Neurol 1963;8:93-111. Pompeiano O. Role of pontine tegmentum for locomotor control in mesencephalic cat. Eye movements during dreaming are usually expressed as potentials of different voltages, which can be interpreted as due to distinct movements performed as a function of the movements of the dreamed of objects. To discuss this issue we will concentrate only on a few hypotheses. This causes the amygdala and hippocampus to become active, which help to influence the brain systems that control sensations, memories, and emotions. 9. Takakusaki K, Ohta y, Mori S. Single medullary reticulospinal neurons exert postsynaptic inhibitory effects via inhibitory interneurons upon alpha-motoneurons innervating cat hindlimb muscles. 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). John Wiley and Sons, New york 1982. Shiromani PJ, Malik M, Winston S, McCarley RW. 123. The result of such conscious identification is a dream. Physiol Behav 1974;12:293-5. Roffwarg HP, Adrien J, Herman J, Pessah M, Spiro R, Bowe-Anders C. The middle ear muscle activity in the neurophysiology and psychophysiology of the REM state. 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. The other is that dreams are caused Candia et al. Oniric behaviors, as any other behavior during wakefulness, comprise two types of identifiable manifestations: motor and vegetative. PMC Dreams and Nightmares in Patients With Obstructive Sleep Apnea: A Review. 94. 8600 Rockville Pike Timo-Iaria C, Valle AC. 48. physiological function. Behav Brain Res 1997;84:109-16. 12. 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). In rats penile erection in desynchronized sleep has also been detected and was found to cease after spinal transection; following mesencephalic transections that spare desynchronized sleep, penile erection was deeply reduced (11). The site is secure. Peyrethon J, Dusan-Peyrethon D. tude polygraphique du cycle veille-sommeil chez trois genres de rptiles. Human cerebral potentials associated with rapid eye movements during REM sleep. Brain Res 1967;5:221-35. The posterior areas affected in this syndrome are the visual areas V3, V3a and V4 (97). Europ J Neurosci 1994;6:1298-1306. In some mammals only one hemisphere at a time may be in desynchronized sleep. New findings on the neurological organization of dreaming: implications for psychoanalysis. Berlucchi G. Mechanismen von Schlafen und Wachen. A nerve growth factor-induced gene encodes a possible trancriptional regulatory factor. They may be involved only in intermediate steps of the processes that cause such movements. It is interesting that the representation of animals in dreams of infants is quite conspicuous. In rats we found similar potentials in the amygdala as related to olfactory dreams, expressed as rostrum movements (32). Bourgin P, Escourrou P, Gaultier C, Adrien J. Although it may happen in any sleep phase, it prevails during the desynchronized phase. Science 1994;265:676-9. Crick F, Mitchison G. The function of dream sleep. 68. Some more recent theories of dreaming emphasize an adaptive function related to emotion and a role in learning and memory consolidation. Bethesda, MD 20894, Web Policies Metabolism during desynchronized sleep tends, in fact, to be equal to or even larger than that of waking (131,132). Foulkes (1982) considered that dreams are so easily forgotten because the brain in desynchronized sleep is in a "reflective state". Some presently available explanations seem science fiction, rather than true science. Timo-Iaria C. Early research on dreaming. The value of r is as high as 0.9618 when theta waves in the hippocampal CA1 field of one side are matched with those in the nucleus reticularis pontis oralis, what points to a close temporal relationship between theta waves in hippocampus and in the nucleus reticularis pontis oralis. It 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. 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. In more recent years several approaches confirmed these findings (89). Psychosomat Med 1975;37:147-59. Gottesman C, Gandolfo G, Zernicki B. 20. Cole AJ, Saffen DW, Baraban JM, Worley PF. 67. Reticulospinal and reticulobulbar tracts are involved in conveying to the motoneurons the impulses that cause oniric movements. 22. Unauthorized use of these marks is strictly prohibited. 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). Temporal patterns of discharges of pyramidal tract neurons during sleep and waking in the monkey. Noda H, Adey WR. REM sleep and dreaming: towards a theory of protoconsciousness. Behav Brain Sci 2000;23:1008-9. As any information consciously identified, a dream triggers a specific behavior, that we call an oniric behavior. Differentiating Oneiric Stupor in Agrypnia Excitata From Dreaming Disorders. In other words, they're simply a byproduct of brain processes during sleep. This site needs JavaScript to work properly. 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. Several authors also quantified the kinds of dreams as related to their sensory content. Frequency clearly increases and becomes regular, as compared with the trend before oniric activity. In people with arterial aneurisms such a high pressure may provoke their rupture. When any part of the brain programs a behavior it sends the program to the cerebellum. Physiological-functioning theor y was supported in a 2009 paper written by J. Allan Carcione A, Santonastaso M, Sferruzza F, Riccardi I. Res Psychother. Before Magoun HW, Rhines R.

Desynchronization is the rule, during this phase, in all cortical electro-oscillograms in humans and other primates. 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. In decerebrate cats eye movements do occur and are integrated below the midbrain (67,95). To what degree, and in what way, implications can be drawn from these findings for the psychology of dreaming is controversial. 66. 37. Front Neurol. 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). Brain warning function for REM-sleep. Arch Ital Biol 1962;100:216-22. Sleep 1999;22:409-18. There is experimental evidence that eye movements are generated near the nucleus of the abducent nerve but Pompeiano (1967) does not agree with this view (10,41). Web5 Theories on dreaming . Studi Psicologici e Clinici di un Alienista. Baust's data regarding the cat are also evident (38). In: Baust, W. 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). J Neurophysiol 1966;29:871-87. 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. WebThis theory also implies that dreams are not independently functional but rather a coproduct of the sleeping brain, reflecting the dreamers physiological and psychological Gassel MM, Marchiafava PL, Pompeiano O. 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. Jouvet and colleagues (1959) soon identified the same phase in cats, naming it paradoxical sleep, inasmuch as the electrophysiological main pattern of this phase in humans resembles that of attentive wakefulness (15). Sleeping and Waking. The other is that dreams are caused by forebrain activation by dopamine. Similarly, in rats any kind of sensory stimulation does immediately mobilize sniffing and vibrissal scanning movements. 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). 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. 101. However, considering the high prevalence of dreams during this phase it should be more appropriately named oniric phase of sleep. According to Mancia (1995), the brain "produces dreams" as "a symbolic process of elaborating, interpreting and reorganizing in narrative sequences all the material accumulated in the memory during waking hours". Functional neuroanatomy of human rapid-eye-movement sleep and dreaming. 43. Soja PJ, Lopez-Rodriguez F, Morales FR, Chase MH. 42. 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. 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. 49. 19. Activity of the red nucleus during deep, desynchronized sleep in the unrestrained cat. Life Science 1989;45:1349-56. 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. Nature, 2002, submitted. J Neurosci 1991;11:2804-11. Miyauchi et al. 30. Our data with rats are quite consistent as to the variation of blood pressure and heart rate during oniric activity. 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. 60. 27. 33. Chaudhuri A. Neural activity mapping with inducible transcription factors. They include facilitation of memory storage, Jung R, Kornmller AE. 14. 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. Aristotle. Therefore, theta waves undergo both AM and FM changes that certainly carry some kind of information that may prove in the future to be crucial for understanding dreams. Salivary, gastric, enteric, pancreatic and billiary secretion and contraction of the smooth muscle of the gastrointestinal viscera are specific vegetative components of feeding behavior, as well as secretion of luteotropic hormone, increase in cavernous blood pressure and vaginal blood flow and several other endocrine adjustments are part and characteristic of sexual behavior. 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). Lovblad KO, Thomas R, Jakod PM, Scammel T, Bassetti C, Griswold M, et al. 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. Brain Res 1970;19:263-75. Despite the fact that many studies have found that mental activity during wakefulness differs from that during dreaming, the mechanisms involved in both may differ as to the degree of control over the release and combination of memorized information in wakefulness and in desynchronized sleep. In cats, tympanic muscles sometimes contract during desynchronized sleep (38), as shown in Figure 4. The heart rate and breathing quickens, and blood pressure rises. 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. 51. J Neurosci 1995;15:3500-8. Hippocrates and Alkmaeon, who discovered that the mind is in the brain, not in the heart, knew that dreams were originated in the brain. Now, the recent advent of deep neural networks (DNNs) has finally provided the novel conceptual framework within which to understand This is an additional fact to point to the activation of other mechanisms capable of producing wakefulness and desynchronized sleep, including dreaming. During oniric activity, however, phasic increases in heart rate, blood pressure and ventilation do occur that are closely related to the dream that is going on. 18. 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). Arch Ital Biol 1965;103:25-44. Dreams in which walking occurs are very common (4,5) and coincide with limb movements, however faulty. 61. Stern W, Forbes WN, Morgane PJ. This may well reflect auditory dreams, as has been found in humans (36,37). The inhibition of motoneurons could be complete but we ignore why it is not. (1997), in their PET studies, found a significant deactivation, in desynchronized sleep, of a large portion of the dorsolateral prefrontal cortex, what was found also by Madsen et al. 8. 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 This organ receives information from the entire body, including the baroreceptors, as shown by Moruzzi (80). 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. 65. 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. Epub 2010 Nov 12. 109. 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. 23. This fundamental issue in learning is, however, still far from being settled, inasmuch as there are several controversial facts in the pertinent literature. J Neurophysiol 1938;1:413-30. NeuroReport 1997;8:3-7. Doricchi F, Violani C. Dream recall in brain-damaged patients: a contribution to the neuropsychology of dreaming through a review of the literature. Foulkes D. A cognitive-psychological model of REM dream production. Inasmuch as all this relevant knowledge is entirely ignored, we hope the present review may help in rescuing it (4). Thus, any study of dreaming also lends itself to psychological scrutiny and clinical application. Curr Opin Neurobiol 1992;2:759-63. Miyauchi S, Takino R, Fukuda H, Torii S. Electrophysiological evidence for dreaming. Proc Assoc Res Nerv Ment Dis. From the spinal cord Marini (1997) recorded slow (delta) regularly oscillating waves during desynchronized sleep (81), which may be related to activation of spinal neurons during dreaming. 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. Desseilles M, Dang-Vu TT, Sterpenich V, Schwartz S. Conscious Cogn. ), Ermdung, Schlaf und Traum, Fischer Taschenbuch Verlag, Sttutgart 1971:173-242. 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). 133. 106. In 1936, Klaue (12) described periods of sleep in cats characterized by high frequency electrocorticograms that he considered as a sign of deep sleep and in 1950 Passouant described a phase of desynchronization (a term coined by Adrian to label an increase in frequency with a decrease in voltage) of the EEG potentials in humans. Chase MH, Morales FR. Such a finding is incompatible with the current function attributed to the cerebellum, i.e., only correction of movements. Moruzzi G. The sleep-wakefulness cycle. Modifications of recurrent discharge of the alpha motoneurons during sleep. There are other definitions of the word dream, too. 127. Valle AC, Timo-Iaria C, Sameshima K, yamashita R. Theta waves and behavioral manifestations of alertness and dreaming activity in the rat. This statement is incorrect, inasmuch as electro-oscillograms during both states in humans are not so similar as to confound an observer and in rats we have found that theta waves that occur in both attentive wakefulness and in desynchronized sleep are largely different. If the animal is kept alive by forced feeding and is kept warm, in six days frontal desynchronization and theta waves in the other cortical areas reappear and then not only wakefulness is fully recovered but also desynchronized sleep, including oniric activity. Such electrophysiological studies demonstrate that the abovementioned sites in the central nervous system are involved in the oniric movements but they do not prove that such structures generate them. From a very weak inhibition in early infancy, it goes up rapidly up to 15 years of age, evolving asymptotically from this period on. Rechtschaffen A, Buchignani C. The visual appearance of dreams. 1. Visual dreams provoke eye movements. 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". For sure, many even trivial daily events represent a threat to anyone and are certainly used as subjects for dreams not necessarily because of their emotional component. 77. 97. Behav Brain Sci 2000;23:867-76. It is usually taken for granted that PGO potentials are essential manifestations for the electrophysiological identification of dreaming activity but such view is not well founded. 130. The main purpose of experimental decerebration is to study the mechanisms of the fundamental posture, that is, the standing posture. However, they ignored that the dreams were produced by the brain. Does early night REM dream content reliably reflect presleep state of mind? Experimental methodologies permitted investigation of the responsiveness of dreams to external stimulation and the effects of deprivation of REM sleep. Kluger J. Heiss W-D, Pawlik G, Herholz K, Wagner R, Weinhard K. Regional cerebral glucose metabolism in man during wakefulness, sleep, and dreaming. Sleep 1973;2:36-42. Fenn WO, Hursh JB. 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. By measuring the voltage of the potential generated by the rotation it is possible to know if the object is near or far. Electroencerph Clin Neurophysiol 1964;17:617-29. His personal oracle, however, disagreed and convinced him that his dreams were warnings from the gods. Proc Natl Acad Sci 1989;86:8737-41. 83. Perspective of Motor Behavior and its Neural Basis. Exp Brain Res 1989;74:11-23. In: C. Guilleminaut, W. C. Dement and P. Passouant (eds.) Later, theta waves were also found in rats during both attentive wakefulness and desynchronized sleep (19,30,31,74-76). Braun et al. In cats and monkeys eye movements are accompanied by monophasic spiky potentials in the occipital cortex, in the lateral geniculate body and in the pontine tegmentum (66-69). 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. Pompeiano O. Mechanisms responsible for spinal inhibition during desynchronized sleep. 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 Stimulus response theory of dream: The stimulus response theory which existed prior to Freud is based upon the associationistic stimulus response view. This theory stresses the relationship between brain changes during sleep and changes in perceptual efficiency. Some disturbing stimuli force activity into one portion of the cerebral cortex.

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. (eds.) The gamma-alpha loop has been shown to play no role in producing the movements that characterize dreaming. Brainstem Control of Wakefulness and Sleep.

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. In rats, heart rate is clearly accelerated during the periods of oniric activity, expressed as rostrum+vibrissae, eye, head, ear and limb movements. Head jerky movements may reflect vestibular dreams. Socrates, Plato, Aristotle and Xenophanes, nearly 2,400 years ago, were opposed to the prevailing view of the phantastikon, that is, mystic apparitions, and to the premonitory character of dreams as their main characteristics. Brain Res 1985;327:362-6. 69. Later, school and work dominate the mental field and the main features in dreams also change accordingly, supporting this hypothesis. Generation of sleep is reasonably well known but not that of dreaming. Arch Ital Biol 1965;103:369-96. In cats, during movements related to dreams such hyperpolarization is reinforced by presynaptic inhibition of afferents to motoneurons. Where do dreams come from? 129. Such movements may take the sleeper to fall off the bed. Those that are specific to certain behaviors. Unable to load your collection due to an error, Unable to load your delegates due to an error. 1996 Sep 12;383(6596):163-6. doi: 10.1038/383163a0. Such hypothesis is grounded on the following steps. 120. Sci Am 1990;263:86-8,90-2,94-6. 76. Brain Res Bull 1992;28:479-84. eCollection 2021 Aug 12. 73. 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. Maquet et al. The meaning of dreams is therefore still an unsolved problem. Behav Brain Res 1995;69:13-22. In some animals, however, a reduction of heart rate and respiration may occur, what also happens during an attentive wakefulness if they are threatened. The very essence of dreams is, certainly, memorized information. 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. Accordingly, they are known as PGO (pontine, occipital cortex and lateral geniculate nucleus) potentials. 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. 74. 21. As pointed Electroencephal Clin Neurophysiol 1987;66:383-90. Neurosci Res 1993;17:127-140. The discovery of the close association between rapid eye movement (REM) sleep and dreaming and development of sleep laboratory techniques ushered in a new era in the study of dreams.
