Bats pre-adapt sensory acquisition according to target distance prior to takeoff even in the presence of closer background objects

Abstract Animals execute sensorimotor sequences to optimize performance of complex actions series. However, the sensory aspects of these sequences and their dynamic control are often poorly understood. We trained bats to fly to targets at different distances, and analysed their sensory behavior befo...
