Each zone may be considered as belonging to each individual hadron (nucleon) in the nucleus or one could even divide the color field in the same hadron into smaller portions of cells further .

Significantly natural organisms do not only possess nervous system; in fact they also evolve genetic information stored in the nucleus of their cells (genotype). Furthermore, the nervous system as a whole is part of the phenotype which is derived from the genotype through a specific development process.
