Dopaminergic control of sleep-wake states.
Dopamine depletion is involved in the pathophysiology of Parkinson's disease, whereas hyperdopaminergia may play a fundamental role in generating endophenotypes associated with schizophrenia. Sleep disturbances are known to occur in both schizophrenia and Parkinson's disease, suggesting that dopamine plays a role in regulating the sleep-wake cycle. Here, we show that novelty-exposed hyperdopami...
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...
متن کاملModelling of auditory evoked potentials of human sleep-wake states.
The shape of evoked potentials is influenced by the level of vigilance, varying with sleep-wake states. In this paper the shape of auditory evoked potentials is modelled by taking two factors, both modulating the underlying neuronal substrate, into account: 'sensory gating' and 'neuronal firing mode'. Under low levels of vigilance sensory gating reduces the amount of neuronal activity reaching ...
متن کاملNative language shifts across sleep-wake states in bilingual sleeptalkers.
STUDY OBJECTIVES To assess language used during episodes of sleeptalking in bilingual children. DESIGN The investigation was accomplished through the parents who, after having received appropriate information, participated by filling out a survey on sleeptalking. SETTINGS The study was performed in three bilingual schools of the Basque country, a region in northern Spain in which two comple...
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...
