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.
