The solution is basing on math tools from AI area. Under the framework of the solution, analyzing how biochemical parameters of the brain and kinds of physiological mechanisms of the brain affect the processes of storing and recalling a piece of information, it’s helpful for understanding the working mechanism of the brain. With the help of quantify model, we can see there is a matching problem of network training sample quantity and network scale. Timing control function of blood circulation and language mechanisms etc. solve thismatching problem by organizing respective sub networks when brain processing different pieces of information because: these physiological mechanisms(timing control function of blood circulation, language mechanism, etc) can cooperate with kinds of biochemical parameters of the brain(e.g. O2concentration, discharge rate of cell, forgotten rate etc.). The solution of matching problem result in high accuracy and efficiency when brain processing information. 【Key words】model of process storing and recalling timing control microcirculation structure risk minimization CNS information processing
