Optoelectric Cannula - multiple electrodes

  • Unit price per 

Ordering Code:
  • Our optoelectric cannulas combine an optical fiber for optogenetics and/or photometry with 1 to 16 electrodes for electrophysiology recordings in freely-moving animals. The electrodes are connected via a 18 pins connector to Doric electrophysiology tethered headstage. We offer tungsten wire electrodes with diameter of 25, 35, 50 microns for single unit, multi units or field potential recording. Custom configurations are available upon request, like the type of electrodes, the number of optical fibers and the disposition of the optical fibers and electrodes.
