Neuro-interfaces Review

In this paper, we provide a brief description of currently existing neural interfaces such as a brain–machine interface, machine–brain interface and bidirectional brain–computer–brain interface. Nevertheless, our aim is not only to provide a review of the current state of the art in these technologies but also to include a philosophical analysis of their fundamental role in the evolution and transformation of cognitive sciences. Also we will show the advantages and disadvantages of different degrees of interface invasiveness. We will highlight the general design schema of them.
