Cirelli and other researchers presented evidence at the neuroscience meeting suggesting that sleep may perform both functions. 奇雷利和其他几位研究人员在此次会议上展示的一些证据显示，此两点可能都是睡眠的功能。
In a study in rats, Cirelli and her colleagues discovered that a molecule that works with the brain chemical glutamate becomes more and more abundant the longer rats are awake. 在一项小鼠试验中，奇雷利及同事发现，随着小鼠清醒时间更久，大脑内部与化学成分谷氨酸共同作用的一种分子就会变得越来越活跃。
