Thomas Stieglitz publishes in FAZ

Prof. Thoma Stieglitz, member of CorTec’s advisory board, has published in today’s edition of Frankfurter Allgemeine Zeitung (FAZ) an article about the state of the art in neurotechnology.

Stieglitz explains what has been achieved so far and provides an outlook on further desiderata to this technology – as well as on mutual developments that already are already dealing with these challenges.

Furthermore, Prof. Stieglitz was invited to give a talk in a series of events on brain research organized by the Hertie Foundation and the FAZ which took place on the 5th of June at the Otto Stern Centre in Frankfurt. Prof. Stieglitz’s talk and the following discussion with philosopher Thomas Metzinger are available online at:
