Psychoanalysis and neurosciences: fuzzy outlines? Notes on the notion of cerebral plasticity.

"Psychoanalysis versus psychiatry" and "unconscious versus brain" are classic oppositions between different perspectives on the human being and mental suffering. This article draws on certain elements of this discussion and reflects on how new ideas about the brain and biology favor closer interaction between psychoanalysis and the neurosciences. These questions are redefined through the notion of cerebral plasticity, by which the brain is open to interaction with the social environment and the influence of psychoanalytical therapy. Conceiving of the brain as a plastic organ allows for the possibility of interchange between psychoanalysis and the neurosciences.
