You'll have to forgive me, I have very little knowledge of biology. However, I read that a brain computer interface less that 50 nanometers in diamater could cross the blood brain barrier, but I am not sure if it is possible when it is ingested or if it has to be injected.
If it is ingested, does anyone know if it could perform the same tasks? Thanks.
