Our Optoelectric Cannula Arrays combine optogenetics and/or photometry with multi-site electrophysiology in freely-moving animals. Our optoelectric cannula arrays consist of an optical fiber (200/250 µm NA 0.66) surrounded by up to 32 electrodes.

This product allows electrophysiological recording and/or stimulation depending on the electrode type. We offer tungsten electrodes (diameter of 25 or 50 µm) for single-, multi-, or field potential recording and platinum/iridium electrodes (diameter of 100 µm) for electrical stimulation.

Custom configurations concerning the type of electrodes, the number of optical fibers, and their disposition are available upon request.
