The Development and Application of Biochemical Analysis of Saliva in the Assessment of the Activity of Nervous System

Biochemical molecules are substantial bases for the function of nervous system. The concentrations of specific molecules are closely linked to the activity and status of nervous system. This paper summarized our previous work on the relationship be-tween some active biochemical molecules and specific activities in nervous system. The results indicated that the levels of some biochemical substances may reflect the function and regulation of the nervous system, which derived easy, fast and cheap methods for assessing the activity and status in nervous system.
