Scientists in Switzerland have developed a novel way to monitor a neuron's electrical activity by bathing it in laser light. The technique, called holographic microscopy, doesn't require the invasive electrodes or dyes typically used to measure cell activity. Researchers say the approach could be used to rapidly screen new drugs designed to protect brain cells.
