Opto-electric Cannula - multiple electrodes

  • Unit price per 


Ordering Code:
  • Our opto-electric cannulas combines 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 as described in the table below :
