This article will present an overview of the debate about the connections between psychoanalysis and neuroscience. In the psychoanalytic camp, the three main groups are identified as: (1) hybridisation, (2) isolation and (3) interlocution. The first group understands the need for creating a hybrid field, as neurosciences can provide psychoanalysis with underpinnings, methodological techniques and firmer concepts of mental function. This idea is developing as the foundation of Neuropsychoanalysis. The second group, marked strongly by the lacanian discourse, rejects any linkage, thinking them epistemologically incompatible, and predicting an inevitable subjugation of psychoanalysis to scientific dictums. Finally the third group understands interlocution, without hierarchification of the models in play, as a fertile ground for the formulation of new hypotheses and the renovation of the conceptual edifice of psychoanalysis.
