Here's some truth some "schizo" tried to propagate years ago.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5470037/Recently certain reports failed to replicate it, however. Which could be genuine, or it could be trying to put the cat back in the bag for whatever reason. The original work was done via the Rockefeller Institute.

However, what if you don't need to surgically implant electrodes? Through RF guided nanotechnology, perhaps implants can be grown in the body.
