SGER: Collaborative Research: Sleep in Nocturnal Bird Migrants: An Interdisciplinary Study

合作研究：夜间鸟类迁徙者的睡眠，一项跨学科的研究弗纳P宾曼保龄球绿色州立大学动物度过他们的生活要么醒着，要么睡着。清醒使动物能够有效地与环境互动，而清醒的表现取决于睡眠，其功能在很大程度上仍然未知。动物可以通过单侧半球睡眠来缓解睡眠和清醒之间的冲突，这是一种独特的状态，在这种状态下，一个大脑半球睡觉，而另一个大脑半球保持清醒。这个跨学科的合作项目利用夜间鸟类迁徙作为自然模型系统来研究睡眠的行为和生理特性，自然发生的睡眠丧失的后果以及伴随睡眠丧失的补偿性调整。大多数鸟类在白天活动，晚上睡觉，当它们的迁徙航班发生在晚上时，它们在迁徙期间休息。通过在夜间旅行，候鸟经历了减少的捕食威胁，改善了飞行的大气条件，并在白天有更多的时间进食。除了夜间迁徙的优点外，鸟类在夜间迁徙必然会失去睡眠，睡眠行为的变化可能会产生不良后果。结合实验室和野外对斯温森画眉（一种洲际候鸟）睡眠的研究，探讨季节性睡眠剥夺的鸟类如何在行为和生理水平上补偿睡眠剥夺。这项研究的贡献是衡量在方法学的应用，睡眠的研究和了解睡眠的功能。

Collaborative Research: Sleep in nocturnal bird migrants, an interdisciplinary study Verner P. BingmanBowling Green State UniversityAnimals spend their lives either awake or asleep. Wakefulness allows animals to interact effectively with their environment, while waking performance is contingent on sleep, the function of which remains largely unknown. An animal may mitigate the conflict between sleep and wakefulness by engaging in unihemispheric sleep, a unique state during which one cerebral hemisphere sleeps while the other remains awake. This interdisciplinary, collaborative project takes advantage of nocturnal bird migrants as a natural model system to study the behavioral and physiological properties of sleep, the consequences of naturally occurring sleep loss, and the compensatory adjustments that accompany sleep loss. Most bird species are active during the day and sleep at night, exceQt during migration when their migratory flights occur at night. By traveling at night a migrating bird experiences reduced threat of predation, improved atmospheric conditions for flight, and more time to feed during the day. Advantages of nocturnal migration aside, birds necessarily lose sleep by migrating at night and changes in sleep behavior could have adverse consequences. Laboratory and field studies of sleep in the Swainson' s Thrush, an intercontinental bird migrant, are combined to ask how seasonally sleep deprived birds compensate for that deprivation at the behavioral and physiological level. The contribution of the study is measured in terms of both application of methodology to the study of sleep and understanding the function of sleep.
