These probes can incorporate fiber optics and/or drug delivery cannula for precise optogenetic stimulation and local drug administration. We offer our electrodes in various designs for acute and long-term (chronic) applications, for instance:

CE-Acute-Insulated-SharpTip

This design is ideal for precise bipolar stimulation (evoked activity or evoked potential studies) in acute experiments. The core electrode (Platinum/Iridium or Stainless Steel) is sharpened to facilitate dura penetration and precise, localized stimulation of the tissue. We use polyimide tubing for insulating the outer Stainless Steel tube, which exposed part forms the other contact. Epoxy insulation separates the two metal contacts. The macroscopic tip has a tapering profile. Two gold male pin connectors provide easy connection to your data acquisition system.
