Night Watch in One Brain Hemisphere during Sleep Associated with the First-Night Effect in Humans
We often experience troubled sleep in a novel environment [1]. This is called the first-night effect (FNE) in human sleep research and has been regarded as a typical sleep disturbance [2-4]. Here, we show that the FNE is a manifestation of one hemisphere being more vigilant than the other as a night watch to monitor unfamiliar surroundings during sleep [5, 6]. Using advanced neuroimaging techni...
متن کاملTime of night and first night effects on arousal response in healthy adults.
OBJECTIVE Several factors, such as homeostatic and circadian influences, may affect the density of cortical and subcortical arousals (AR). The purpose of this study was to examine the time-of-night and the first night effect on AR response. METHODS AR were classified into microarousals (MA), phases of transitory activation (PAT), delta (D-burst) and K-complex burst (K-burst). The AR density a...
متن کاملFirst-night effect in the chronic fatigue syndrome.
Since the magnitude of the first-night effect has been shown to be a function of medical conditions and of settings in which polysomnographies are performed, it is essential to evaluate the habituation phenomenon in each case in order to determine the optimal recording methodology. A first-night effect was evidenced in certain cases of chronic fatigue syndrome, but not in others. To clarify thi...
متن کاملSleep Misperception and First Night Effect in Laboratory Research
Study Objectives: Cortical hyperarousal, observed in insomnia individuals, could be influenced by sleep quality and objective sleep misperception. Usually, to be considered as a first night effect, a decrease in the quality of sleep during the first recording night in the laboratory is observed. The objectives of this study are to examine cortical arousal differences according to sleeper types ...
