Theoretical and empirical investigations of echolocation in bat groups

Echolocating bats emit intense calls, and use the returning echoes to detect their surroundings. In groups, due to mutual jamming, individual bats are expected ...

Echolocating bats accumulate information from acoustic snapshots ...

While some studies in bats have offered indirect evidence that bats anticipate target motion (10, 11, 13), our results provide direct empirical ...

Echolocation: Smart bats click twice - eLife

The acoustic representation of the outside world in the midbrain of a bat becomes more precise as it uses double clicks to locate closer objects.
