Modern technology for recording deep-brain activity involves sharp metal electrodes that penetrate the tissue, causing damage that can compromise the signal and limiting how often they can be used.
A rapidly growing area in materials science and engineering is to fix the problem by designing electrodes that are softer, smaller, and flexible — safer for use inside the delicate tissues of the brain. Just last week, researchers from the University of California, San Diego, reported the development of a thin, flexible electrode that can be inserted deep within the brain and communicate with sensors on the surface.
But what if you could record detailed deep-brain activity without piercing the brain?
A team of researchers (as it happens,...
