The reliable interaction of technical systems with nerves and the brain is the goal of neuroimplants. Electrodes must reliably and with long-term stability record bioelectric signals and stimulate them electrically without damaging or destroying tissue and implant. In their tutorial, researchers at Center BrainLinks-BrainTools at the University of Freiburg led by Maria Asplund, Christian Böhler and Thomas Stieglitz have for the first time compiled comprehensive test procedures that describe the global state of the art and allow a comparison of the function of neuroimplants.
