Abstract

A newly designed intrafascicular electrode for chronic neural recording was studied by implanting 12 electrodes in the radial nerves of 6 cats for 6 months. Action potentials were monitored at specified intervals throughout the experiment. The number and size of the signals recorded suggest that this type of electrode provides information that is appropriate for feedback control in functional electrical stimulation (FES) systems. Histology of the nerve revealed that the implants are biocompatible and that little damage is caused by the presence of the electrode.

  • Longitudinal intrafascicular electrodes offer good selectivity for stimulation and for multiunit extracellular recording, and their geometry makes them suitable for long-term implantation.

    “The LIFEs offer good selectivity for stimulation (Nannini and Horch, 1991; Yoshida and Horch, 1993) and for multiunit extracellular recording (Goodall et al., 1991; McNaughton and Horch, 1994; Yoshida and Stein, 1999) , and their geometry, make them suitable for longterm implantations (Lefurge et al., 1991) .”

  • Histology of animal nerves with metal or polymer longitudinal intrafascicular electrodes implanted for six months showed the implants were biocompatible and caused no damage, although a slight increase in connective tissue around the implant site was evident long-term.

    “The histology of animal nerves that had metal or polymer LIFEs implanted for a period of 6 months revealed that the implants are biocompatible and that no damage was caused by the presence of the electrode, although a slight increase in connective tissue surrounding the implant site was evident in the longterm (Lefurge et al., 1991; Lawrence et al., 2002) .”

  • LIFEs evaluated in a 6-month cat experiment produced signals of good quality at the beginning, but there was a slight decrease during 6 months; the authors expect a functional lifetime of 18 to 24 months if the same decrease in quality continues.

    “LIFEs were evaluated in a 6-month cat experiment. The electrodes produced signals of good quality at the beginning, but there was a slight decrease during 6 months. The authors expect a functional lifetime of 18 to 24 months if the same decrease in quality continues [179].”

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.
