Discriminative and affective touch: Sensing and feeling.

Abstract

The multimodal properties of the human somatosensory system continue to be unravelled. There is mounting evidence that one of these submodalities-touch-has another dimension, providing not only its well-recognized discriminative input to the brain, but also an affective input. It has long been recognized that touch plays an important role in many forms of social communication and a number of theories have been proposed to explain observations and beliefs about the "power of touch." Here, we propose that a class of low-threshold mechanosensitive C fibers that innervate the hairy skin represent the neurobiological substrate for the affective and rewarding properties of touch.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Observations of McGlone et al. on hedonic coupling suggest two qualia (touch and pleasure) may be linked in ways that could imply homology.

    “I would also cite here the observations of McGlone et al. (2014) on hedonic coupling, that two qualia (touch and pleasure in their example) appear to be linked in ways that could imply homology.”
  • C-tactile afferents are specially attuned to social touch, particularly affiliative touch such as gentle stroking, and have been found in all mammals studied.

    “Subsequent research on the importance of touch in mammals has discovered the existence of nerve fibres called C-tactile afferents that are specially attuned to social touch, particularly affiliative touch such as gentle stroking [62,63]. These have been found in all mammals studied, including primates, pigs, rats, mice, guinea pigs, rabbits and cats [64,65].”

  • Spinal reflexes and the spinothalamic pathways are engaged with peripheral interfaces while bypassed with brain interfaces.

    “Fourth, spinal reflexes (Schouenborg, 2008) and the spinothalamic pathways (important for affective touch, see McGlone et al., 2014) are engaged with peripheral interfaces while bypassed with brain interfaces.”

  • The main tactile fibers underlying discriminative touch are myelinated Ab fibers.

    “The main tactile fibers underlying discriminative touch are myelinated Ab fibers.”

  • Tactile input has a broad impact on bodily function and percept, ranging from simple reflexes to arousal regulation to complex social processes, and is highly influential in numerous central nervous system processes.

    “Given that tactile input has a broad impact on bodily function and percept, ranging from simple reflexes to arousal regulation to complex social processes, it is also highly influential in numerous central nervous system processes ( Ayres, 1972 ; McGlone et al., 2014 ; Lane et al., 2019 ).”

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.
