Abstract

Information about the spatial structure of tactile stimuli is conveyed by slowly adapting type 1 (SA1) and rapidly adapting (RA) afferents innervating the skin. Here, we investigate how the spatial properties of the stimulus shape the afferent response. To that end, we present an analytical framework to characterize SA1 and RA responses to a wide variety of spatial patterns indented into the skin. This framework comprises a model of the tissue deformation produced by any three-dimensional indented spatial pattern, along with an expression that converts the deformation at the receptor site into a neural response. We evaluated 15 candidate variables for the relevant receptor deformation and found that physical quantities closely related to local membrane stretch were most predictive of the observed afferent responses. The main outcome of this study is an accurate working model of SA1 and RA afferent responses to indented spatial patterns.

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?

  • Certain key features of the object, such as the presence and orientation of edges, are enhanced at the periphery due to skin mechanics and the geometry of the receptive fields.

    “Certain key features of the object, for example the presence and orientation of edges, are enhanced at the periphery due to skin mechanics (Fig. 4A) (Phillips and Johnson, 1981;Sripati et al., 2006) and the geometry of the receptive fields (Pruszynski and Johansson, 2014).”

  • Sophisticated models that simulate different aspects of transduction do exist.

    “Indeed, sophisticated models that simulate different aspects of transduction do exist.”

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.
