Doppler shift compensation performance in Hipposideros pratti across experimental paradigms

Abstract: A central aim of neuroethological research is to discover the mechanisms of natural behaviors in controlled laboratory studies. This goal, however, comes with challenges, namely the selection of experimental paradigms that allow full expression of natural behaviors. Here, we explore this problem in echolocating bats that evolved Doppler shift compensation (DSC) of sonar vocalizations to yield close matching between echo frequency and hearing sensitivity. We ask if behavioral tasks influence the precision of DS… Show more

“…Echolocating bats are renowned for their short-term vocal plasticity. They not only dynamically adjust the structure of echolocation signals to ongoing navigation and foraging tasks 37 , 38 , 39 but also rapidly modify signal features to cope with interfering sounds. 40 , 41 , 42 , 43 , 44 By contrast, little is known regarding the ability to adaptively adjust signal parameters at a longer timescale, which is relevant to long-term learning.…”
