Scientist Scott Keene invented an organic computer chip that interfaces with brain cells chemically.

He states that the new computer chips have been tested with rat medulla brain cells ex-vivo. By operating chemically, rather than electronically, and using organic materials the new type of computer chip is a closer simulation to the neurons usually found in the body than electrical neural stimulators (e.g. pacemakers or cochlear implants).
