The same neurons that help bats navigate through space may also help them navigate collective social environments (Nature). Many mammals, including bats and humans, are believed to navigate with the help of a brain structure called the hippocampus, which encodes a mental ‘map’ of familiar surroundings. For example, as one walks around the neighbourhood or…
