The Seminar of the Freudian Field in San Sebastian, in its Cycle of Conferences: "A Psychoanalytical Look on Current Issues", has counted on the presence of Fabián Fajnwaks on February 9th to address the current topic of the brain and what neurosciences are determined to discover through it. Why are the secrets of subjectivity sought in the secrets of the brain? Will this central organ fulfil its promises and respond to the thousands of university articles devoted to understanding everything that science does not yet know and the millions of euros devoted to research?
