Chapter 6 goes on to discuss how difference-based coding and the associated neuronal mechanisms of rest–stimulus and stimulus–rest interaction enable and predispose to the constitution of self and objects as distinct from the brain. I specifically focus on early defense mechanisms, such as internalization (e.g. introjection) and externalization (e.g. projection), as they enable and predispose the brain to first constitute and later defend self and objects. Since both internalization and externalization are crucial when constituting self and objects, they are postulated to enable and predispose to brain–self and brain–object differentiation. This chapter thus has an essential role in that it bridges the gap between the neuroscience of the brain and the psychodynamic concept of the psychic apparatus as characterized by objects and a self.
