The safety of neural interfaces varies based on the type. Non-invasive methods like EEG are generally safe with minimal risks. Invasive methods, on the other hand, carry risks associated with surgical implantation, such as infection, bleeding, or tissue damage. However, advancements in surgical techniques and materials are continually being made to improve safety. It's essential to consult with medical professionals and be informed about potential risks before opting for any BCI procedure.
