Abstract

There is growing interest in intracortical microstimulation as a means of providing sensory input in neuroprosthetic systems. We believe that precisely controlling the timing and parameters of stimulation in closed loop can significantly improve the efficacy of this technique. Here, we present a system for closed-loop microstimulation in awake rodents chronically implanted with multielectrode arrays. The system interfaces with existing commercial recording and stimulating hardware. Using custom-made hardware, we can stimulate and record from electrodes on the same implanted array and significantly reduce the stimulation artifact. Stimulation sequences can either be preprogrammed or triggered by neural or behavioral events. Specifically, this system can provide feedback stimulation in response to action potentials or features in the local field potential recorded on any of the electrodes within 15 ms. It can also trigger stimulation based on behavioral events, such as real-time tracking of rat whiskers captured with high-speed video. We believe that this system, which can be recreated easily, will help to significantly refine the technique of intracortical microstimulation and advance the field of neuroprostheses.

  • The blanking technique and digital signal processing have been used to cancel the artifact.

    “The blanking technique and digital signal processing (Erez et al., 2010) have been used to cancel the artifact (Olsson et al., 2005; Venkatraman et al., 2009; Kent and Grill, 2011; Myers et al., 2011; Zoladz et al., 2012; Wei-Ming et al., 2013; Yi et al., 2013; Bozorgzadeh et al., 2014; Elyahoodayan et al., 2019).”

  • Such a stimulation artifact can be observed in most closed-loop recording and stimulation circuits.

    “Such a stimulation artifact can be observed in most of the closed-loop recording and stimulation circuits (Yoshida and Horch, 1996; Blum et al., 2007; Venkatraman et al., 2009; Mc Laughlin et al., 2012; Ng et al., 2012; Xu et al., 2012).”

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.
