Sleep is an ancestral and primitive behaviour, an important part of life thought to be essential for restoration of body and mind. As adults, we spend approximately a third of our lives asleep and as we progress through life there are certain shifts in ...

Paradoxical sleep as a programming system [PDF]
The concept of ‘psychological individuation’ i.e ‘intraspecific variability’ is essential for evolution as stated by Mayr (1958). It has been recently revived by the study of Bouchard (1990) in homozygous twins separated at birth and reared in different environments. These twins still retain identical psychological idiosyncratic reactions.

Sleep is characterized as rapid eye movement (REM) and non-rapid eye movement (NREM) sleep. Studies suggest that wake-related neurons in the basal forebrain, posterior hypothalamus and brainstem and NREM sleep-related neurons in the anterior-hypothalamic

Glucocorticoids are not responsible for paradoxical sleep deprivation-induced memory impairments
Study Objectives: To evaluate whether paradoxical sleep deprivation-induced memory impairments are due to release of glucocorticoids, by means of corticosterone inhibition with metyrapone.Design: The design was a 2 (Groups [control, paradoxical sleep ...

Sleep Deprivation in the Rat: IV. Paradoxical Sleep Deprivation [PDF]
Twelve rats were subjected to paradoxical sleep deprivation (PSD) by the disk apparatus. All PSD rats died or were sacrificed when death seemed imminent within 16-54 days. No anatomical cause of death was identified. All PSD rats showed a debilitated appearance, lesions on their tails and paws, and weight loss in spite of increased food intake.

Paradoxical interventions involve asking patients to maintain or exaggerate the symptoms they wish to eliminate, with the aim of reducing them. These techniques received empirical support, particularly in the treatment of sleep-onset insomnia, during the

The involvement of noradrenaline in rapid eye movement (REM) sleep mentation
Noradrenaline, one of the main brain monoamines, has powerful central influences on neurobiological processes in the forebrain which support the mental activities occurring during the sleep–waking cycle. Noradrenergic neurons are activated during waking,

Sleep and Paradoxical Sleep in Ruminants.
SummaryThis study proved that ruminants have the physiologic capacity for sleep and paradoxical sleep. Daytime ruminant sleep in goats was transient and polyphasic, averaging 5.1 ± 0.6 minutes per episode. The frequency was variable, ranging from 0 to 6 episodes during daytime.
