Lichtenberg lines are long, intricate, wavy burns that can appear on someone temporarily after receiving a massive electric shock. "They don't really stick around. They're these fernlike, superficial burns of the skin," said Claypool. There could be long-lasting effects on the brain as well, including potential memory loss, seizures or muscle spasms. "There's really nothing unique, long term, from lightning. You can have these things from any kind of brain injury," said Claypool.
