Ever since Elon Musk’s Neuralink showcased the monkey Pager controlling a game with its mind, Brain-Computer Interfaces (BCIs) came to the spotlight.

A brain-computer interface (BCI), also known as a brain-machine interface, mind-machine interface, or neural-control interface, has been around for a while. In fact, the research on BCIs started already in the 1970s at the University of California.

This initial research focused on restoring damaged sight, hearing and movements, and BCI research has made significant progress since then. The focus of the research is on pattern recognition, and together with developments in AI and machine learning, this has enabled researchers to become very good at this. A BCI detects minuscule changes in the energy radiated by the brain when you think, recognising patterns in the brain.

Thanks to Magnetic Resonance Imaging (MRI), we can now understand in extreme detail which parts of the brain light up when thinking about something. This has enabled scientists to read dreams, read our thoughts and know our feelings.

However, an MRI machine is not very portable, is very expensive – an entry-level machine starts at $250.000, and it requires a team of researchers or doctors to operate. Therefore, the race is on to create brain-computer interfaces that …
