There is a contemporary proposal to increase the interdisciplinary work between the psychoanalysis and the neuroscience fields, wich purpose is to facilitate the integration of both of them. In this paper I examine critically the question about a minimum possibility of articulation between these domains of knowledge, and my starting point are the epistemological presuppositions that are in their specific bases. These thoughts encompass so my psychoanalyst's perspectives like the theorethical instrumental of a pragmatic perspective about science, wich have been unfolded in a vast literature about philosophy/sociology of natural sciences in the last decades.
