How Bats Stay on Target Despite the Clutter
July 28, 2011
Neuroscientists at Brown University have learned how bats can remain on target despite obstacles. The key lies in bats' neural response to echoes from their sonar pulses: Differences in delay as short as three microseconds between parts of an echo is enough to tell the bat the object may not be its target. The research could lead to more precise targeting by sonar-led vehicles. Results are published in Science.
