    Researchers design technology that sees nerve cells fire

    Researchers at Stanford University, Palo Alto, California, have created a noninvasive technology that detects when nerve cells fire based on changes in shape. The method could be used to observe nerve activity in light-accessible parts of the body, such as the eye, which would allow physicians to quantitatively monitor visual function at the cellular level. The study was published in the journal Light: Science and Applications . The work was funded by the National Eye Institute, part of the National Institutes of Health. When nerves fire, there's a change in the electrical potential (trans-membrane voltage) in the cell. Current techniques ...
