“…Results from brain-research suggest that it should be possible to build technical medical devices which interact with the neuronal activity patterns of the brain to ease the loss of life quality and partially restore the lost functionality (e.g. creating visual perception [Schiller and Tehovnik, 2008, Dobelle, 1999, Schmidt et al, 1996 and extracting information from neuronal activites [van Gerven et al, 2009, Andersen et al, 2010, Lebedev and Nicolelis, 2006, Ifft et al, 2012).
