Bats are 3-D cartographers
Special cells in the mammal’s brain chart its path as it flies
Holy flying fruit bats!
Neurons called place cells help Egyptian fruit bats, Rousettus aegyptiacus, navigate three-dimensional spaces, researchers report April 18 in Science.
By implanting electrodes in the bats’ brains and strapping on lightweight wireless recording devices to their heads, researchers measured neural activity as the animals flew up, down and around a room. Individual place cells perked
