Researchers
have designed a minimally-invasive device that can selectively and dynamically
illuminate multiple brain regions for optogenetics applications. The device is a waveguide comprising a single
thin optical fibre with a sharp, tapered tip coated with gold (except for the
tip). Emission of desired modes of light
was permitted at specific sites along the taper by locally removing the coating
to create windows. Each window could be
addressed by adjusting the angle of the incident light on the input facet of
the fibre. In vivo proof of principle experiments demonstrated the
effectiveness of the device.
