Neuroscientists investigate neuronal communication with ultra-thin fiber-based endo-microscope

This summarizes a paper in which researchers created a microscope probe using a single, 110 µm diameter optical fiber. An interesting technique from this that I had not seen before, was that the end of the optical fiber is angled and coated with aluminum to create a mirror looking perpendicular to the length of the fiber. This enables researchers to image living cells less intrusively.
