Doppler detection triggers instantaneous escape behavior in scanning bats Dataset

Description

By presenting phantom echoes to perching horseshoe bats, in this study, we revealed that they use only the Doppler shifts, not changes in the echo delay, as a cue for approaching objects. This suggests that these bats do not perceive motion in the spatiotemporal dimension as in vision, but they directly detect velocity, allowing instantaneous response to approaching threats. This dataset shows changes in the characteristics of the emitted echolocation call as a response of the bats to each stimulus.
