US researchers have developed a sensor - embedded plastic wrap that allows for safer and more accurate brain mapping . Scientists at the university of California , San ##medical and bio ##medical Hospital have created a new brain mapping tool , which is based on a conductive polymer rather than the usual metal coating . The device is about a thousand times thinner than existing clinical tools and also has a far higher electrode density , meaning the device can sit closer to the brain and provide better readings .
