I don't think you're making it up, denuseri. I'm just saying that strictly equating function with structure is too simplistic.
And I'm saying that the brain is also designed to perform many functions.The foot is designed to preform a large number of functions Thorne, not just the one you mentioned, yes it can kick things and run and walk etc...it cant flap and make you fly though...to do that it would have to have a different overall structure!
Yes, the arrangement of the carbon atoms changes, forming a more dense crystalline structure when compressed to form diamonds, not so dense when forming coal. But the atoms themselves do not change! What I'm saying is that the activity of the brain is similar, in that the basic structure remains the same, but the overall interaction between structures, the electro-chemical signals which the brain uses, can vary greatly, and thereby give varying results. Function being influenced by structure, but not absolutely defined by it.So are carbon atoms...which when pressure is apllied to for a long enough duration and tempurature just so happen to become really dense and become diamond...the atomic structure however is still there yet becuase its arranged differently diamond has different aplications compared to its less dense forms just like any other structure does when its altered..it too takes on different characteristics.
