The common view that nerves transmit impulses through electricity is wrong and they really transmit sound, according to a team of Danish scientists.
The Copenhagen University researchers argue that biology and medical textbooks that say nerves relay electrical impulses from the brain to the rest of the body are incorrect.
“For us as physicists, this cannot be the explanation,” said Thomas Heimburg, an associate professor at the university’s Niels Bohr Institute. “The physical laws of thermodynamics tell us that electrical impulses must produce heat as they travel along the nerve, but experiments find that no such heat is produced.”
