First come, first served: Neuronal processing of multi-echo streams in the auditory cortex of echolocating bats

Echolocating bats emit acoustic pulses that get reflected off objects. The spatial information carried by the echoes enable bats to avoid obstacles in darkness. Usually, every pulse is followed by a cascade of echoes arising from multiple objects. By using echolocation sequences where a single pulse is followed by an echo cascade, we recently demonstrated that cortical neurons predominantly respond to the leading echo. Responses to lagging echoes from a cascade were suppressed suggesting that sp
