PMID-27571550 Stable long-term chronic brain mapping at the single-neuron level.

  • Fu TM, Hong G1, Zhou T1, Schuhmann TG, Viveros RD2, Lieber CM.
  • 8 months with only 800nm of Su-8 (400nm of insulation!!). This is both surprising and very impressive; we have to step up our game!
  • In a mouse, too - their surgical technique must be very good. Mice only live ~ 2 years anyway.
  • Figure 3 -- stability -- incredible.
  • Recording sites were bare platinum, 20um diameter; stimulation sites were also bare Pt, 150um dia.
    • No plating or mircowire-fets, so far as I can see; electrode impedances were stable at 200 - 600k (supplementary figure 12).
