Review of optical fiber technologies for optogenetics

Abstract Research in the field of Optogenetics has matured to the extent that in vivo implementations are more frequent in the literature. The majority of these employs different variants of optical fibers, including standard optical fibers, fiber bundles and tapered fibers. In the present contribution we review the application of optical fibers in optogenetics, in terms of critical requirements (biocompatabiliy, minimal invasiveness, spatial accuracy, etc) for in vivo demonstrations.
