Brain-Computer Interface review

Brain-Computer Interface (BCI) is a device that allows direct communication path between central nervous system and external devices without peripheral nerves dependency. Brain-Computer Interface and its applications reached beyond medical applications, it is used to enhance, improve, restore or replace functions or it can be used as a research tool. Stakeholders of the field have developed future plans and the ethical in research. the multidisciplinary nature of Brain-Computer Interface is based on neuroscience, signal processing, biomedical sensors, and hardware. This paper aims to present briefly the current state and the future of Brain-Computer Interfaces. The future works of the author are based on hardware approach using System-On-Chip combined with novelty memristor crossbar memory, which can be used to emulate axons and neurons directly in the hardware.
