Biocompatibility of intracortical microelectrodes: current status and future prospects

Open access

Abstract

Rehabilitation of sensory and/or motor functions in patients with neurological diseases is more and more dealing with artificial electrical stimulation and recording from populations of neurons using biocompatible chronic implants. As more and more patients have benefited from these approaches, the interest in neural interfaces has grown significantly. However an important problem reported with all available microelectrodes to date is long-term viability and biocompatibility. Therefore it is essential to understand the signals that lead to neuroglial activation and create a targeted intervention to control the response, reduce the adverse nature of the reactions and maintain an ideal environment for the brain-electrode interface. We discuss some of the exciting opportunities and challenges that lie in this intersection of neuroscience research, bioengineering, neurology and biomaterials.

  • The results suggest that silicon-based, penetrating microelectrode arrays could provide the stability required in a clinical device.

    “The results therefore suggest that silicon-based, penetrating microelectrode arrays could provide the stability required in a clinical device (11, 32-34) but further investigations in more subjects and over a longer period of time are needed.”

    From Visual percepts evoked with an intracortical 96-channel microelectrode array inserted in human occipital cortex (2021) · cites this paper as [32]

    The Introduction says long-term viability and stability remain a problem for available neural electrodes. Challenges and Future Perspectives adds that keeping intracortical microelectrodes biologically and electrically viable for many years remains difficult. Although the paper discusses penetrating arrays, it does not present silicon-based arrays as likely to provide the stability required for a clinical device. (LLM, conf=0.79)

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.
