This article needs a rewrite. I can't understand what's going on here:
> But if the person presses against only a cool bar, only coolness is experienced; if the person presses against only a warm bar, only warmth is experienced.
> Researchers have used the illusion to demonstrate that burning pain sensation is in fact a mixture of both cold and heat pain and that it is only the inhibition of the cold pain "channel" that reveals the heat component.
How does the point about inhibition follow from the experiment? Is the cold pain channel somehow inhibited by the grill, but still active when only touching the hot part? idgi
- GordonS 5y ago> burning pain sensation is in fact a mixture of both cold and heat pain Hmm, interesting. I know I'm off at a tangent here, but as an aside, I have small fibre neuropathy and struggle to describe the pain - sometimes I think it's more like a burning sensation, other times I think it's more like a painfully cold sensation.
- matt-attack 5y agoGeez glad I’m not the only one. Can’t here to find a cogent description.
- yetihehe 5y ago> Is the cold pain channel somehow inhibited by the grill No, cold-pain channel is inhibited, when you touch something normally hot. When you touch something very hot, hoth channels fire and you have "burning hot" sensation. So when you touch something normally hot and cold which are very near on your body, you have overlap (like blurring of channels) and you feel that it's burning your skin.
