Chronically implanted epineural electrodes for repeated assessment of nerve conduction velocity and compound action potential amplitude in rodents

Murphy, Blake, Krieger, Charles, Hoffer, Joaquin-Andres·2004·Journal of Neuroscience Methods

Abstract

Implanted epineural electrodes were used for the longitudinal assessment of peripheral nerve conduction velocity (NCV) and compound action potential (CAP) amplitude in rats. Custom-fabricated stimulating and recording electrodes were sutured over the tibial and sciatic nerves, respectively, and were used for weekly recordings of CAP latency and amplitude. Intra-day variability of nerve conduction velocity measurements had coefficients of variation of less than 2% for same day recordings from individual subjects. A clear trend in recovery of the NCV values following implant was observed over the 7-week trial period. These results demonstrate that implanted epineural electrodes provide a reliable method for chronic, in vivo monitoring of nerve conduction parameters in rodents.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • After epineural electrode implantation, fibrous tissue grows around the electrode as part of a foreign body reaction, which stabilizes the electrode, and signals from the nerves become accurate and reproducible.

    “After the implantation procedure, fibrous tissue grows around the electrode as part of a foreign body reaction and this is profitable since it stabilizes the electrode. Following this stabilization process, signals from the nerves are both accurate and reproducible [37, 45].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
