The researchers inserted a bundle of fine micro wires, capable of recording the action potential of a single neuron, through the hollow inner canal of depth electrodes implanted as part of the epilepsy procedure.

In their case, when oxygen-containing bubbles form in the regolith, they do so freely, rather than on the surface of an electrode.

One end of the DNA strand is attached to an electrode, and the other end is attached to another bit of DNA that binds to a desired protein.

Wendy Swain, who had electrodes in the wrong place for 11 years, leading to difficulty walking and a facial twitch, said: “They’ve made my life hell.”

Using a computer algorithm, the researchers can design the spots for EEG electrodes on the patient's scalp.
