困觉机制的假设模型

he relationship between sleep and brain is always the research interest of life science. This paper gives out a reasonable hypothetical model for the precondition of the sleep---the sleepiness. This so-called “Sleepy Factor Model” mainly refers the cyclic movement of the sleepy factors and their relative position relates their function and regulation of the downstream mechanisms of sleepiness (e.g. the production of the chemical material ). This hypothetical model is also tried to explain the everyday-life phenomenon related to sleepiness including side-effects of some drugs. It turns out this hypothetical model can explain them quite well, hoping this model will be some academic direction to the research of the sleepiness mechanism.
