III. EXTRAORDINARY ORGANS ->Brain

As early as in the book Nei~ing there were descriptions of the brain one of which is as follows: "The brain is a sea of marrow. Its upper part is under the scalp of the vertex, point Baihui (Du 20) and its lower part reaches point Fengfu (Du 16)." Subsequently a further understanding of the brain was obtained; that is, it was recognized in Yixue Yuanshi (Origin of Medical Science) that "the sense organs, i.e., the ears, eyes, mouth and nose, are in the head close to the brain. Owing to their highest and most obvious position, they may perceive objects, which will impress the brain directly and remain in the brain". Also, it was suggested in Yilin Gaicuo (Medical Correction) that thinking and memorization are the main functions of the brain. As mentioned previously, the essence of the kidney produces marrow that forms the brain. The filling of the "sea" of marrow depends on the essence of the kidney. Furthermore, the heart, which houses the mind, and the liver, which dominates the unrestraint and patency of vital functions, are also related to mental activities. A tenet of traditional Chinese medicine, therefore, is that mental activity is dominated by various organs, the heart being the main one.
