Sleep-wake cycles are closely tied with the circadian period of other bodily functions. Optimal synchronization is essential for troublefree alterations of sleep and wake periods. The neurophysiologic control areas are in various of the brain are far apart from each other for which reason a great variety of possible causes for sleep difficulties do exist. It has been shown recently that spezific mono-aminergic and cholinergic systems in the brain stem do control sleep. A case study will show that it is possible to improve sleeping difficulties with the serotonin precursor L-Troyptophan.
睡眠-清醒周期与其他身体功能的昼夜节律密切相关。最佳同步对于睡眠和清醒阶段的顺利交替至关重要。大脑中不同的神经生理控制区域彼此相距甚远，因此存在各种各样导致睡眠困难的可能原因。最近的研究表明，脑干中特定的单胺能和胆碱能系统确实控制着睡眠。一项案例研究将表明，使用血清素前体L-色氨酸有可能改善睡眠困难。
