Echolocating bats determine target range by measuring the time delay between the emitted biosonar pulse and the returning echo. We have found two types of neurons in a part of the auditory cortex of the mustached bat, Pteronotus parnellii rubiginosus, which demonstrate selective sensitivity to echo delays, and therefore, target range.
