PMID-23860226 A carbon-fiber electrode array for long-term neural recording.

  • Guitchounts G1, Markowitz JE, Liberti WA, Gardner TJ.
  • We describe an assembly method for a 16-channel electrode array consisting of carbon fibers (<5 µm diameter) individually insulated with Parylene-C and fire-sharpened. The diameter of the array is approximately 26 µm along the full extent of the implant.
  • Fibers from http://www.goodfellowusa.com/
    • young's modulus of 380GPa vs. tungsten 400GPa.
    • Data available from Toho Tenax
  • The absence of any report of single neuron isolation in HVC with a fixed chronic electrode implant underscores the difficulty of recording small cells (8-15um soma) with an implant whose damage length scale is large relative to the target neurons. (!!)
