Speak your mind! – Pilot clinical study with severely paralyzed patients

CorTec is part of an international clinical study that will enable severely paralyzed people to communicate again – with the help of an implantable brain-computer interface. It is a vision that has been at the core of CorTec’s DNA since its inception more than 10 years ago by now: Brain-Computer Interfaces (BCI) that enable severely […]
