Nine participants in the experiment, the researchers found a lack of sensitivity of at least one toe. Most often it was the ring, middle, index or middle finger. The sensitivity of the thumb and mesince was preserved in almost all.
Error and confusion in defining the finger began when scientists concerned fingers "secondary" feet. On the leading leg in most cases, people accurately guessed which finger was touched scientists.
Presumably, the denser the location of the toes and reduced sensitivity compared to the fingers. Nothing wrong with that, scientists believe, no.
