The states of the world are remarkably varied, and so are those of the behaving animal whose needs for survival require a system for adaptive matching between states within itself and those of the environment. This matching requirement becomes most sophisticated in relation to the so-called higher brain functions. So far, the thesis on the structural bases of higher brain functions that is pursued in this book can be summarized roughly as follows. The epigenetic processes of development lead to structures within evolved nuclei and laminae that are highly and individually variant in their intrinsic connectivity. These structures provide the basis for the formation of large numbers of degenerate neuronal groups in different repertoires linked extrinsically in ways that permit reentrant signaling. Mapping and somatotopic ordering arise evolutionarily from the need to maintain a reference for the
