As the key organ of human, the brain has projection area corresponding to every part of the body, indicating that the damage on human body will locate a corresponding projection area in the brain. The primary injury on the distal end will produce secondary lesion in the projection area of brain, featuring as "bipolar lesions". The volume transmission (VT) theory and propagated sensation along meridians (PSAM) in TCM provide core guidance for the treatment of "bipolar lesions". The tendency to lesion of PSAM is achieved through volume transmission, which is also called "propagated sensation tendency to lesion of VT". From three aspects, VT can treat bipolar lesions, formatting a ring closed path. With VT as main treatment and wiring transmission as supplemented treatment, it has a more comprehensive guidance for treatment, and this theory may play an essential guiding role in the future treatment development for diseases.
