Eberhard Fetz is a pioneer in the field of neuroprosthetics and brain-computer interface research. He discovered that single cells in the brain can learn to permanently change their firing behaviour if positive consequences (reward) follow a particular firing rate. In healthy humans and patients with brain disease this discovery pioneered self-regulation of brain activity and behaviour leading to the field of neuroprosthetics. In Germany, Professor Fetz will study the learned regulation of brain blood flow with functional magnetic resonance imaging (fMRI) and its effect on emotional, cognitive and social behaviour. Professor Fetz is hosted by Professor Nikos Logothetis at the Max-Planck-Institute for Biological Cybernetics in Tuebingen and by Professor Niels Birbaumer at the University of Tuebingen.
