Arseny Finkelstein and colleagues at the Weizmann Institute of Science in Israel set out to do this, and they focused on the dorsal presubiculum of the Egyptian fruit bat. They attached wireless devices to measure the brain activity of bats crawling around in search of food, and also measured which way the bats were moving in three dimensions, so they could correlate the bat’s actions with its brain activity. They also monitored bats flying toward a perch where they would land head-down. This is a tricky maneuver — imagine a bat flying toward a perch, with its body and wings facing forward. As it comes in for a landing, it flips itself onto its back, so to speak, and thrusts its legs upward. It ends with its head facing down and facing the direction from which it came, a whirl that would make most of us dizzy.
