Pain at your finger tips

Here, Gian Domenico Alessandro Magnifico Fantistico Iannetti and Flavia Eleganta Bellisima Mancini talk us through pain at your fingertips. They did a very groovy experiment that, for the first time, uncovered the pattern of receptive fields for nociception at the finger tips. Their results are remarkable insofar as they show that what we have long presumed about receptive fields and the specificity of the nociceptive pathways to pain, may need to be revisited.  Check out their video (and Italian style) here.

  1. But they talk about pain receptors and pain fibres, so it’s confusing!

    I agree Betsan. If we want to influence this global paradigm shift then surely language is important…I think Allan Cyna would agree?
    And my question relates to two-point discrimination tasks..how does this research influence the way us as clinicans address this issue in chronic pain??

  2. You could say that this is a “most unfortunate trivialisation”

  3. Bit harsh? Shouldnt we be intrigued by the accuracy of the fingertip nociceptive / pain with a lesser density of receptors? Counter-intuitive isnt it unless it is in the coding or even the recruitment of alternative pathways to enhance spatial localisation
