Michael Nirenberg of the America's Podiatrist website says soles ticklish feet is a good thing for a variety of reasons. Researchers who have conducted experiments on ticklishness still don't have all the answers as to why humans and other very, such as cats, rats and monkeys, are ticklish or what exactly goes on between nerve endings and the brain during tickling. Because nerves on the foot's sole have both touch and pain receptors that carry information about either sensation along neural pathways to the brain, it's difficult to separate the two when talking about ticklishness, says the American Scientist website.
The pain and pleasure of having your feet tickled is linked to these soles and touch nerve ticklish.
Add to that the anticipation of the tickle, and the whole business invokes a "tonic top-down regulation of neural activity," as teen pinay naked in MIT's "Journal of Cognitive Neuroscience"—which means the brain very primed and ready to react before the ticklish touches skin. It also explains why a person can't tickle himself:
