The topic of this monograph is in one respect as audacious as it is far-reaching for theoretical neuroscience. It is nothing less than this: the real Existenz of, objectively valid ground in Nature for, and applied metaphysic of the somatic code (historically called the neural code). The existence of a somatic code was hypothesized by von Neumann almost sixty years ago. This paper establishes that the somatic code exists in Nature and provides the Realerklärung (real explanation) of its Existenz. When one considers that the Nature of the somatic code has been sought by theoretical neuroscience almost since the day this field of research was established, "audacious" is not too strong a word to apply to the claim I am making here.
