Multi-Fiber Optoelectrodes

NeuroNexus now offers multi-fiber optoelectrodes for expanded optogenetics applications in a compact, robust package. We can currently configure up to 8 fibers per probe (one fiber per shank). Because of the physical limitations of optical fibers and NeuroNexus microelectrode arrays, there are some design constraints. Multi-fiber optoelectrodes are only available in LP (bare ferrule) packages. Please contact us for more information.
