...Antoine Hoffmann; Einat Couzin-Fuchs ABSTRACT Motion plays an essential role in sensory acquisition. From changing the position in which information can be acquired to fine-scale probing and active sensing, animals actively control the way they interact with the environment. In olfaction, movement...

... of sensory information. Apart from the strategies investigated here, actively sensing animals can further adjust information acquisition by controlling the beam shape of emitted energy. Narrower beams prevent uninformative side echoes while broader beams widen the field of view. Investigating how changes...

... that rely on active sensing to guide navigation. Four echolocating bats ( Eptesicus fuscus ) were trained to use an acoustic landmark to find and navigate through a net opening for a food reward. In experimental trials, an object serving as a landmark was placed adjacent to a net opening and an object...

.... Our hypothesis is that these movements are a form of active sensing in which the animal self-stimulates its electroreceptors to match the demands of the nervous system. Examples may include the requirements of high-pass filtering in primary afferents ( Nelson et al., 1997 ), the spatiotemporal demands...
