Abstract

What does the hand tell the brain? Tactile stimulation of the hand evokes remarkably precise patterns of neural activity, suggesting that the timing of individual spikes may convey information. However, many aspects of the transformation of mechanical deformations of the skin into spike trains remain unknown. Here we describe an integrate-and-fire model that accurately predicts the timing of individual spikes evoked by arbitrary mechanical vibrations in three types of mechanoreceptive afferent fibers that innervate the hand. The model accounts for most known properties of the three fiber types, including rectification, frequency-sensitivity, and patterns of spike entrainment as a function of stimulus frequency. These results not only shed light on the mechanisms of mechanotransduction but can be used to provide realistic tactile feedback in upper-limb neuroprostheses.

  • The responses of SA1 afferents roughly track contact pressure, while those of RA and PC afferents track changes in pressure.

  • The peripheral response to an indented object is not just proportional to the indentation depth; RA and PC afferents also respond to the first two derivatives of time-varying depth.

    “The peripheral response to an indented object is not just proportional to the indentation depth as RA and PC afferents also respond to the first two derivatives of time-varying depth (Dong et al., 2013;Kim et al., 2010).”

  • The combined population response is determined not only by contact pressure but also by its first and second derivatives.

    “The combined population response is thus determined not only by contact pressure but also by its first and second derivatives (Dong et al., 2013;Kim et al., 2010).”

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.
