摘要:

ABSTRACT.Our knowledge of the visual cortex has increased tremendously over the past ten years based on studies in subhuman primates. Over a dozen separate cortical visual areas have now been described in monkeys (Van Essen and Maunsell 1983). This paper will review our current understanding of the anatomy and physiology of the visual cortex in monkeys and human beings. Specifically, this paper will discuss the striate cortex, and how object recognition, visual motion analysis and visual spatial localization is processed in the extrastriate visual cortex in monkeys and humans.

摘要:

ABSTRACT.It has become apparent in the last few years that many sleep complaints expressed by patients may involve cessation of breathing during sleep (apnea) or severe leg jerks (periodic movements in sleep-PMS), causing brief arousals throughout the night. The most commonly used practice for screening of these two disorders has been an all-night laboratory polysomnogram, which records sleep/wake, respiration, and leg movements. This technique involves, for the patient, a high cost, restriction of movement, and an unfamiliar and sometimes frightening setting. During the last few years our laboratory has used a portable ambulatory recording method to screen for sleep apnea and PMS, establishing a reliable and comfortable screening procedure in the patient's own home. The overall cost of an initial screening is thus reduced, as is the time spent by the technician who, in the laboratory, would monitor the patient all night. This method allows more patients to be screened by one technician and allows easy application for patients confined to bed. In addition to the time saved through this technique, it is also more easily tolerated by sensitive patients, such as the elderly.As knowledge in sleep disorders becomes more defined and available, it becomes desirable to offer such a time- and cost-saving method for initial screening of sleep disorders.

摘要:

ABSTRACT.Sleep myoclonus is stereotyped, repetitive, nonepileptic lower extremity movements occurring primarily in non REM (NREM) sleep. The condition is seen most frequently in the middle aged and the elderly, and is a significant cause of insomnia and excessive daytime somnolence. The lower extremity movements must be distinguished from those associated with the encephalopathies, the restless legs syndrome, sleep starts, and epilepsy. Polysomnography is required for the diagnosis. The etiology of sleep myoclonus is unknown, and treatment has been only marginally successful.

摘要:

ABSTRACT.Depth EEG findings (obtained in patients with intractable epilepsy) demonstrate the occurrence of sleep spindles in the frontal region and especially in the supplementary frontal motor cortex at a time when the scalp EEC and the patient's behavior may indicate light drowsiness or even wakefulness. Implanted thalamic electrodes in the human also show relatively early occurrence of spindles. These findings suggest the existence of a preparatory state for sleep in an apparently waking person.Elevated temperature of the periocular region has been demonstrated with the use of thermography. These periocular are likely to indicate a peripheral mechanism of sleep induction. There is reason to presume that dissociation between central and peripheral mechanisms of sleep induction may exist.
