Brain Energetics During the Sleep-Wake Cycle
Brain activity during wakefulness is associated with high metabolic rates that are believed to support information processing and memory encoding. In spite of loss of consciousness, sleep still carries a substantial energy cost. Experimental evidence supports a cerebral metabolic shift taking place during sleep that suppresses aerobic glycolysis, a hallmark of environment-oriented waking behavi...
متن کاملIntroduction Paroxysmal Motor Behaviors Occurring during Sleep Are Classified Either as Sleep-related Epilep- Tic Seizures
PAROXYSMAL MOTOR BEHAVIORS OCCURRING DURING SLEEP ARE CLASSIFIED EITHER AS SLEEP-RELATED EPILEPTIC SEIZURES OR AS PARASOMNIAS. In 1977 Pedley and Guilleminault1 defined an atypical form of epilepsy, called episodic nocturnal wanderings, characterized by paroxysmal ambulation and bizarre behavioral manifestations during sleep. Even in the absence of recorded nocturnal seizures, the presence of i...
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 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 کاملThe Nature of Tic Disorders
Tics are defined, rather vaguely, in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994) nosology as a recurrent, non-rhythmic series of movements (of a non-voluntary nature) in one or several muscle groups. Tics are usually divided into simple and complex tics of a motor, sensory, phonic or cognitive nature. In practice, simple tics have t...
