Abstract

We present a laser-engineered fiber-optic implant capable of emitting light from over 1,000 independent sites within a single fiber. By selectively launching light into specific channels, the emission patterns can be dynamically reconfigured, enabling versatile light delivery with a single fiber implant. To demonstrate its efficacy, distinct defensive behaviors were evoked in freely moving mice by targeting different depths of the superior colliculus. This reconfigurable light delivery across large tissue volumes opens new possibilities for massively parallel causal investigation of neural activities across brain regions through optical manipulation.
