What are Brain-Computer-Interfaces? 🤔
Brain-Computer-Interfaces (BCI) enable direct information transfer between a brain and a technical circuit. By reading out thoughts or mental commands, they can act as neurotechnological input system to provide machine control independent of speech and movement. Because they do not require the actuation of any muscle, BCI open up fundamentally revolutionary operating possibilities.

What are possible applications? 👀
The main goal of BCI is to replace or restore useful function to people disabled by neuromuscular disorders such as amyotrophic lateral sclerosis, cerebral palsy, stroke, or spinal cord injury. Brain-computer interfaces may also prove useful for rehabilitation after stroke and for other disorders. In the future, they might augment the performance of surgeons or other medical professionals. Brain-computer interface technology is the focus of a rapidly growing research and development enterprise that is greatly exciting scientists, engineers, clinicians, and the public in general.

What limitations do exist? 🛠️
Brain-computer interfaces need signal-acquisition hardware that is convenient, portable, safe, and able to function in all environments. Brain-computer interface systems need to be validated in long-term studies of real-world use by people with severe disabilities, and effective and viable models for their widespread dissemination must be implemented. Finally, the day-to-day and moment-to-moment reliability of BCI performance must be improved so that it approaches the reliability of natural muscle-based function.
