Implantable Optical Fiber
Implantable optical fibers are ideal for experiments requiring only optical stimulation without electrical recording from nearby neurons. The implantable fiber length can be customized between 2 - 10 mm; the standard length is 2.5 mm. Note that the base of the NNc (not shown) is designed to sit on the skull; therefore when determining the desired fiber length, one needs to take into account skull thickness.
Implantable optical fibers are available with 105 μm core diameters, which are ideal for Optoelectrode and fiber implant users who want to minimize tissue damage.
