Yes the brain is also...like most organs of the body made do a wide variety of things...duh. That doesnt change the fact that the structures of the brain are what they are and that they determine what functions if any one is capable of.

And its the doctors and scientists, both east and west and everywhere inbetween who are saying that structure does indeed equal function, plain and simple: the complicated part is figuring out every nuiance and function of every structure or structual variation and how it exactly works in relationship to its various functions....a task which is a long duanting one but they make more and more proccess in every day.

Open any modern day science school book book if you dont believe me.

In the case of acupuncture and most eastrn medicines, the question was approached in the exact opposite manner from the west...european doctors studied such things from observations of structures first...its what early gross anatomy is all about...where as in the east they looked at function first and experiemneted (much of the time through trial and error just like in the west) and found that when A is done to the body, it alleviated or corrected whatever B was in as minimally an envasive manner as possible. Thankfully the medical communities of both east and west have begun to embrace each others ways of thinking instead of clinging to pig headed euro-centrism and come to formally recognize and study in more detial the other way of thinking in equal measure. A fact that is easily recognized if one were to open any modern day medical textbook.

As for carbon...when the arangments between the atoms changed...so did the stucture...stucture is completely dependent upon such arrangments to begin with...its basic science 101...its why the lump of coal's function is so very different from the diamonds. Yes the little atoms themselves are still all carbon,,, but like little bricks in a house, how they are arranged determines the difference between there being a plain wall, a window or door or a thick castle wall etc etc.
