The tiny electrodes were only 17 microns apart -- less than half the width of a human hair -- and the smallest movement of the brain slices could skew their results.

In a conventional electrolyser, bubbles in the water can be clingy and stick to the electrodes, clogging up the process and leading to energy loss.

When charging a battery, charged ions are inserted into one of the battery's electrodes.

With software developed by Horn's team, the researchers pinpointed the precise location of DBS electrodes in each patient and created a common map of the circuits associated with patients' symptom improvement.

A study from earlier this year unveiled advances in technology that uses implanted brain electrodes to recreate the speaking voice of someone who has lost speech ability, which can be an outcome from stroke.
