Sight off the Bat

While hunting for dinner, the big brown bat must hone in on flitting insects and keep track of its surroundings to avoid crashing into them. Now, scientists have taken a peek at what’s going on in these bats’ brains while they swoop and dive. They identified a brain region that helps the animals map where objects are in relation to their own bodies, and saw that individual brain cells changed their behavior while the bats focused their attention on a particular object.
