Allan Rechtschaffen
1998 Perspectives in biology and medicine  
A number of sleep theories have been put forth and fluctuations in biologic patterns have been measured during sleep, but the function of sleep is not yet understood. Sleep can be understood as fulfilling many different functions but intuition suggests there is one essential function. The discovery of this function will open an important door to the understanding of biologic processes.
