To establish a model to investigate the nature and action mechanism of channels and collaterals on the basis of modern physiology. Methods:Through literature research on the relationship between channel and brain, and in combination of the knowledge of brain functions and modern brain imaging study, the researcher points out the nature of channel and how it works, by which the channel- related traditional theories and phenomena could be well explained.Results:Not only have the channel- related traditional theories and phenomena been well explained, moreover, the speed is calculated. Conclusion:Channels and collaterals have the nature of self awareness.
