ABSTRACT
The tactile proto-objectual tension caused by the mother and the internal tension due to somatic excitation are both present in certain privileged areas during maternal interaction. The endogenous representations of a sexual type are therefore associated with the maternal representations that are gradually being integrated. Mothers have an innate ability to realize whether their children are in general responding to the corporeal stimuli they are providing, and this makes it easier for the maternal rhythms of stimulation to combine with the endogenous rhythms of reception. This non-symmetry of endogenous modulation makes it possible to conceptualize numerous structural forms of pairings between exogenous and endogenous activation patterns during maturation. Cortical encoding, which is more objectual, is continuously behind proto-objectual encoding during brain maturation. It is first of all necessary to briefly consider the maturation of the reticulum, which is still largely incomplete at birth.
