Population registration of echo flow in the big brown bat’s auditory midbrain
Abstract
Echolocating bats navigate through cluttered environments that return cascades of echoes in response to the bat’s broadcasts. We show that local field potentials from the big brown bat’s auditory midbrain have consistent responses to a simulated echo cascade varying across echo delays and stimulus amplitudes, despite different underlying individual neuronal selectivities. These results suggest that population activity in the midbrain can build a cohesive percept of an auditory scene by aggregating activity over neuronal subpopulations.
