Expecting pain

Paul Ingraham ARCHIVEDMicroblog posts are archived and rarely updated. In contrast, most long-form articles on PainScience.com are updated regularly over the years.

Mike Thacker:

What I am proposing is a predictive processing model of pain… [in which] each level of the system is predicting what is happening at the level below, receiving information from it and using that information to update its predictions.

Simply put, what we expect to hurt is a major factor in what actually does. A predictive model for pain processing echoes how other perception works. For instance, vision is predictive: we don’t so much “take it all in” as we “see what we expect to see, with some spot checks for accuracy and consistency.”

This is the MICROBLOG: small posts about interesting stuff that comes up while I’m updating & upgrading dozens of featured articles on PainScience.com. Follow along on Twitter, Facebook, or RSS. Sorry, no email subscription option at this time, but it’s in the works.
