Neural 'extension cord' developed for brain implants 19 January 2007 - New Scientist.
Smith, at Pennsylvania. Quite a nice trick.
"A group of neurons is cultured on top of an array of 96 electrodes covered with a protein coating that causes them to attach. When placed 100 microns (about the width of a human hair) from another patch of neurons on a separate plate, the cells grow towards them, eventually joining neuron clumps together.

Growing neural circuits into an 'extension cord'
Neural 'extension cord' developed for brain implants 19 January 2007 - New Scientist.
Smith, at Pennsylvania. Quite a nice trick.
"A group of neurons is cultured on top of an array of 96 electrodes covered with a protein coating that causes them to attach. When placed 100 microns (about the width of a human hair) from another patch of neurons on a separate plate, the cells grow towards them, eventually joining neuron clumps together.
A motor is then used to slowly draw the two plates apart – causing the nerve fibres to continuing growing, at up to 1 cm each day. "We plan to use the free end to interface with the nervous system," Smith told New Scientist, "while the other end interfaces with a computer."
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."
