PMID-4670862[0] A sweet new multiple electrode for chronic single unit recording in moving animals.

  • 7 or more 25um individually teflon coated Pt-Ir wires
  • Supported by 26ga hypodermic tubing.
  • coated in melted dextrose (no water, keep stirring it) via dipping.
  • connection via colloidal silver epoxy. we use that.
  • Units recorded within 48 hours. "Electrodes cmoe to exhibit ha high degree of shock-resistance and neurtral bouyancy with respect to immediately-adjacent brain tissue."
  • Durable to 2-3 months of 51 individual electrodes in 8 rats.
  • 1kHz impedance 500k.
