Many breakthroughs in medicine have been made from studying rats. Antonia, Laura and Ellie discuss several studies of rat behaviour that have mapped how parts of the brain work and discuss how the results could be applied to humans to develop prosthetic limbs or help recover memory after a brain injury. They look at studies where rats are tickled until they laugh (https://www.scientificamerican.com/ar...) , learn to drive cars (https://www.iflscience.com/teaching-r...) , navigate virtual reality and perform a Jedi mind trick (https://www.iflscience.com/rats-can-f...) .
