The BrainSTAR Project has to major objectives: The first objective is to develop a technologies and a microsystem platform for wireless miniaturized brain stimulation and recording suitable for small animal research and treatment of human neurological and neurodegenerative diseases in a longer run. The second ovbjective is to validate the technologies developed in three different application contexts (basic neuroscience/neurobiology, medical therapies, and pharmacological R&D) and provide feedback to the technology developers/ These are ambitious goals requiring a strong multi-disciplinary consortium and an interdisciplinary approach of working closely together
