Tests have already shown that electrical signals can be transmitted in both directions along the cord. “Tests in animal models are next,” says Smith. Connecting the chord to electrodes outside of the brain means the reaction of neurons to non-organic material can be controlled. In future, the cord could connect an amputee’s nerves to a sophisticated prosthetic, he says, and might even offer a way to connect artificial eyes or ears to the brain.
In Europe most researchers in this field are using non-invasive EEG. There are also brain implants with pill sized chips Wikipedia describes the brain gate interface Nanowires can connect to individual neurons
