Abstract
Sleep is a fundamental state for maintaining the organism homeostasis. Disruptions in sleep patterns predispose to the appearance of memory impairments and mental disorders, including depression. Recent pre-clinical studies have highlighted the antidepressant-like properties of the synthetic compound 2-phenyl-3-(phenylselanyl)benzofuran (SeBZF1). To further investigate the neuromodulatory effects of SeBZF1, this study aimed to assess its therapeutic efficacy in ameliorating neurobehavioral impairments induced by sleep deprivation (SD) in mice. For this purpose, a method known as multiple platforms over water was used to induce rapid eye movement (REM) SD. Two hours after acute SD (24 h), male Swiss mice received a single treatment of SeBZF1 (5 mg/kg, intragastric route) or fluoxetine (a positive control, 20 mg/kg, intraperitoneal route). Subsequently, behavioral tests were conducted to assess spontaneous motor function (open-field test), depressive-like behavior (tail suspension test), and memory deficits (Y-maze test). Brain structures were utilized to evaluate oxidative stress markers, monoamine oxidase (MAO) and acetylcholinesterase (AChE) activities. Our findings revealed that SD animals displayed depressive-like behavior and memory impairments, which were reverted by SeBZF1 and fluoxetine treatments. SeBZF1 also reverted the increase in lipoperoxidation levels and glutathione peroxidase activity in the pre-frontal cortex in mice exposed to SD. Besides, the increase in hippocampal AChE activity induced by SD was overturned by SeBZF1. Lastly, cortical MAO-B activity was reestablished by SeBZF1 in mice that underwent SD. Based on the main findings of this study, it can be inferred that the compound SeBZF1 reverses the neurobehavioral alterations induced by sleep deprivation in male Swiss mice.

Abstract
Sleep and wakefulness are instinctive behaviours that are present across the animal species. Rapid eye movement (REM) sleep is a unique biological phenomenon expressed during sleep. It evolved about 300 million years ago and is noticed in the more evolved animal species. Although it has been objectively identified in its present characteristic form about half a century ago, the mechanics of how REM is generated, and what happens upon its loss are not known. Nevertheless, extensive research has shown that norepinephrine plays a crucial role in its regulation. The present knowledge that has been reviewed in this manuscript suggests that neurons in the brain stem are responsible for controlling this state and presence of excess norepinephrine in the brain does not allow its generation. Furthermore, REM sleep loss increases levels of norepinephrine in the brain that affects several factors including an increase in Na-K ATPase activity. It has been argued that such increased norepinephrine is ultimately responsible for REM sleep deprivation, associated disturbances in at least some of the physiological conditions leading to alteration in behavioural expression and settling into pathological conditions.

Abstract
This paper focuses on the successive historical papers related to medulla oblongata (M.O.) intracerebral connections, its activities and ascending influences regulating sleep waking behavior. The M.O. certainly influences the quantitative and qualitative processes of waking. However, its neurophysiological properties are often concealed by those of the upper-situated brain stem structures. The M.O., particularly the solitary tract nucleus, is involved in sleep-inducing processes. This nucleus seem to act as a deactivating system of the above situated reticular formation, but it also impacts directly on the thalamocortical slow wave and spindle-inducing processes. The M.O. is significantly involved in paradoxical sleep mechanisms. Indeed, the mesopontine executive centers are unable to induce paradoxical sleep without the M.O. Moreover, stimulation of the solitary tract nucleus afferents can induce paradoxical sleep, and the M.O. metabolic functioning is specifically disturbed by paradoxical sleep deprivation. Finally. there seems to be a paradoxical sleep Zeitgeber. Our current knowledge shows that this lowest brain stem level is crucial for sleep waking mechanisms. It will undoubtedly be further highlighted by future electrophysiologial and neurochemical studies.

Abstract
Rapid eye movement sleep deprivation (REMSD) is a potent stressor in rats. Behavioral abnormalities such as passive and active avoidance, locomotor activity, problem solving, sensory information processing, and the development of adaptive copping strategy in response to repeated stress are among the earliest obvious symptoms of REMSD, the mechanism for which remain largely unknown. The aim of this study was to determine whether 96 h of REMSD causes changes in monoamine neurotransmitters concentrations in rat forebrain regions (frontal cortex, FC; parietal cortex, PC, and striatum) that are involved in mediating higher brain functions such as attentional mechanisms, sensory information processing, and locomotor activity, which are severely affected in REMSD conditions. Rats were subjected to 96 h of REMSD using inverted flower pot water tank technique. To account for the stress associated with water tanks, a tank control group (TC) was included where the animals could reside comfortably on a large pedestal in the water tank. Regional brain concentrations of norepinephrine (NE), dopamine (DA), dihydroxyphenyacetic acid (DOPAC), L-3,4-dihydroxyphenylalanine (L-DOPA), homovanillic acid (HVA), 5-hydroxytryptamine (5-HT), and 5-hydroxyindoleacetic acid (HIAA) were determined by electrochemical detection using high-performance liquid chromatography. The concentrations of serotonin and its metabolite, HIAA, was reduced in the frontal and parietal cortexes of REMSD rats compared with TC or cage control (CC) group. NE, DA, DOPAC, and HVA concentrations in FC and PC of REMSD animals were remained unchanged compared with TC or CC rats. A significant increase in the concentrations of DA metabolites was observed in the striatum of REMSD rats when compared with CC and TC rats. There was a 29 and 31% increase in the concentration of striatal DA in REMSD group compared to the TC and CC groups, respectively; however, these percentages were not statistically different. Striatal NE, 5-HT, and HIAA concentrations were not significantly different among the three groups. These results suggest that 96 h of REMSD alters dopaminergic and serotonergic systems in different locations in rat brain. The effect of REMSD on the serotonergic systems are localized in the cerebral cortex, whereas dopaminergic metabolism is increased in the striatum.

Abstract
Adenosine has been implicated in the regulation of rapid eye movement sleep (REMS). In an attempt to understand the mechanism of production of adenosine in relation to REMS it was hypothesized that should it be involved in REMS, the latter's deprivation is likely to affect its synthetic machinery. Hence, male albino rats were deprived of REMS by the flower pot technique and the activity of 5'-nucleotidase, an enzyme responsible for adenosine synthesis, was estimated in the cerebrum, cerebellum and brain stem. Suitable control experiments were conducted to rule out the non-specific effects. The results showed that 5'-nucleotidase activity decreased only after 4 days deprivation and in the cerebrum only; while short-term (2 days) deprivation did not affect the enzyme activity in any of the brain areas. The altered enzyme activity returned to baseline level after recovery from REMS deprivation. The results from other control experiments suggested that the effects were primarily due to REMS deprivation and not due to non-specific factors. It is proposed that if adenosine is involved in REMS, its production is unlikely to depend on 5'-nucleotidase or it may account primarily for EEG desynchronization.

Abstract
1. Effect of REM sleep (REMs) deprivation treatment on clozapine response in the forced swimming test was investigated. 2. Clozapine significantly increased the swimming activity in REMs-deprived mice at a dose of 5 mg/kg (i.p.) which did not affect the activities in the control groups. 3. Physostigmine (0.3 mg/kg, i.p.), an acetylcholinesterase inhibitor, blocked the increasing effect of 5 mg/kg clozapine on swimming activity in REMs-deprived animals. 4. These results suggest that the REMs deprivation treatment-induced enhancement of effect of clozapine on swimming activity is mediated by the functional change of central cholinergic system following the treatment.

Abstract
Monoamine oxidase, monoamine oxidase-A, and monoamine oxidase-B activities were compared in free moving, rapid eye movement sleep-deprived, recovered, and control rat brains. The activities were estimated in the whole brain, cerebrum, cerebellum, whole brainstem, medulla, pons, and midbrain. The flowerpot method was used for continuing deprivation for one, two, or four days. Monoamine oxidase activity decreased significantly in the cerebrum and the cerebellum of the sleep-deprived rats, whereas monoamine oxidase-A and monoamine oxidase-B were differentially affected. Medullary MAO-A was the first to be affected, showing an increase after just one day of rapid eye movement sleep deprivation, while longer deprivation decreased its activity. The activity of monoamine oxidase-B was not significantly affected in any brain areas of the deprived rats until after two days of rapid eye movement sleep deprivation. All the altered enzyme activities returned to control levels after recovery. Control experiments suggest that the decrease was primarily caused by the rapid eye movement sleep deprivation and was not due to nonspecific effects. These findings are consistent with past studies and may help to explain earlier observations. The results support the involvement of aminergic mechanisms in rapid eye movement sleep. The plausible reasons for the changes in the activities of monoamine oxidases, after rapid eye movement sleep deprivation, are discussed.

Abstract
Since rapid eye movement (REM) sleep deprivation has been reported to affect the neuronal excitability in the brain, it was hypothesized that a change in the neuronal membrane-bound Na-K ATPase activity might be at least one of the factors inducing such a change. Therefore, in this study rats were deprived of REM sleep by using the platform technique and enzyme activity was estimated in the whole brain, in different regions of the brain and in microsomal preparations. Deprivation was carried out for varying periods and suitable control experiments were conducted to rule out the possibility of nonspecific effects. The observation supported our hypothesis and showed primarily that the deprivation increased the enzyme activity in the rat brain. It showed also that the pons and the medulla were the first sites to be affected by deprivation. The probable mechanism producing such a change is discussed.

Abstract
As reviewed here and elsewhere in this symposium, acetylcholine, in conjunction with other neurotransmitter systems, plays a very important role in the regulation of circadian and sleep-wake states. To briefly recapitulate, several current basic concepts about the regulation of sleep-wake states include: (a) REM sleep, or at least its phasic events (eye movements and PGO spikes), are promoted by cholinergic neurons originating within the peribrachial regions [LDT/PPT] (Mitani et al., 1988; Shiromani et al., 1988; Datta et al., 1991; Shouse and Siegel, 1992); (b) REM sleep may be inhibited by noradrenergic and serotonergic neurons in the locus coeruleus and dorsal raphe, respectively (Siegel, 1989; Steriade and McCarley, 1990; Jones, 1991); (c) stages 3 and 4 (Delta) sleep are inhibited by cholinergic terminals from basal forebrain to cortex (Buzsaki et al., 1988) and from LDT/PPT to thalamus (Steriade and McCarley, 1990; Steriade et al., 1991); (d) Delta sleep is modulated by complex serotonergic mechanisms; for example, it is increased by pharmacological antagonists of 5HT2 receptors (Declerck et al., 1987; Dugovic et al., 1989; Benson et al., 1991), although the mechanism and neuroanatomical site at which this effect occurs is unknown. Given the importance of mACHR mediation of components of REM sleep, it is unfortunate that so little is known about the distribution of the various subtypes of mACHRs in brainstem areas which regulate REM sleep. mACHR subtypes have been identified by molecular, biological and pharmacological methods.(ABSTRACT TRUNCATED AT 250 WORDS)
