S. Ramachandran have demonstrated--the brain constructs a plausible hypothesis or pattern or scene. In his theory of neuronal group selection, Gerald Edelman--drawing on the data of neuroanatomy and neurophysiology, of embryology and evolutionary biology, of clinical and experimental work, and of synthetic neural modeling--proposes a detailed neurobiological model of the mind in which the brain's Central role is precisely that of constructing categories--first perceptual then conceptual--and VB of an ascending process of "bootstrapping" where through repeating recategorization at higher and higher levels, consciousness is finally achieved. This, for Edelman, every perception is a creation and every memory a re-creation or recategorization.

The attunement here between Freud's view and Edelman's is striking; here, at least, one has the sense that psychoanalysis and neurobiology can be fully at home with one another, congruent and mutually supportive.  And it may be that in this equation of Nachtra:glichkeit  with "recategorization" we see a hint of how the two seemingly disparate universes--the universes of human meaning and of natural science--may come together."
