متن کاملEffects of bilateral lesion of the locus coeruleus on the sleep-wake cycle in the rat
Introduction: Noradrenergic cells in LC participate in the process of cortical activation and behavioral arousal. The evidence suggests that locus ceoruleus (LC) plays an important role in the sleep-wake cycle. The aim of this study was stereological estimation of cavity caused by lesion and assessment of sleep stages after bilateral lesion of the LC. Materials and Methods: Male Wistar rats we...
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...
متن کاملCircadian control of the sleep-wake cycle.
It is beyond doubt that the timing of sleep is under control of the circadian pacemaker. Humans are a diurnal species; they sleep mostly at night, and they do so at approximately 24-h intervals. If they do not adhere to this general pattern, for instance when working night shifts or when travelling across time zones, they experience the stubborn influence of their circadian clock. In recent yea...

Medication is indicated for only a limited number of children's sleep disorders. However, correctly chosen and supervised, pharmacological treatment may be justified and helpful. For a given sleep problem it is important to identify the underlying cause (or sleep disorder) which often calls for treatment of a non-medication type. Where medication is appropriate, cautious use and careful review ...
