Caffeine attenuates paradoxical sleep deprivation induced- memory impairment during paradoxical sleep windows in rats
There is considerable evidence to support the hypothesis of relationship between paradoxical sleep (PS) and learning–memory processing. It has been suggested that PS is important in memory retention at the specific time course called PS windows (PSW). The time of PSWs occurrence and duration of these PSWs following the training sessions and, the neurochemical nature of PSWs has not been well kn...

متن کاملParadoxical sleep deprivation increases plasma endothelin levels.
The endothelins (ET-1, 2 and 3) constitute a family of 21 amino acid peptides with potent biological activities. ET-1 is one of the most potent endogenous vasoconstrictors so far identified and its increased concentration in plasma appears to be closely related to the pathogenesis of arterial hypertension as well as to obstructive sleep apnea (OSA). OSA patients exhibit repetitive episodes of a...
متن کاملPhenomenological Study of Paradoxical Phase and Reverse Paradoxical Phase of Sleep.
There is, as is well known, a peculiar phase of sleep which is known by different names; paradoxical phase (p. p) (JOUVET 1960), activated sleep (DEMENT 1958), early morning sleep (GIBBS and GIBBS 1950), recently REMP (KLEITMAN and DEMENT 1957) and so on. The major features of this stage are: LVFA (low voltage fast activity) or waking pattern in EEG, behavioral deep sleep with high sensory thre...
متن کامل[Sleep-wake cycle mechanisms].
Neurochemically distinct systems interact regulating sleep and wakefulness. Wakefulness is promoted by aminergic, acetylcholinergic brainstem and hypothalamic systems. Each of these arousal systems supports wakefulness and coordinated activity is required for alertness and EEG activation. Neurons in the pons and preoptic area control rapid eye movement and non-rapid eye movement sleep. Mutual i...
