Dynamic sensory–motor oscillation and cerebral development

Drawing from Freud’s Project, the author proposes a model of cerebral development whose sensory–motor structure is defined by a frontal–occipital oscillatory dynamic with a twofold function: the oscillation explains the formation and maintenance of mother–infant attunement in cerebral growth, while, at the same time, also explaining the functioning of the projective–introjective dynamic at the basis of psychoanalytic theory. The oscillatory dynamic, according to this perspective, operates as a “bridge” between two seminal theoretical models of developments—the psychoanalytic and the infant research model—which, in turn, leads to the formulation of some neurological hypotheses on how oscillation regulates the elaboration of maternal interaction in the infant’s brain, and how the mother may act to modify it. The paper discusses how the oscillatory dynamic offers an innovative framework for the reconceptualization of the development of mentalization, the function of mirror neurons, and, most interestingly, of the development of language, explaining the non-verbal properties of ordinary linguistic communication and the function of oscillation in the regulation of information exchange processing.
