Laminar Distribution of Spectrotemporal Receptive Field Subtypes in the Primary Auditory Cortex of Echolocating Bats.

ABSTRACT: The primary auditory cortex (A1) is crucial for processing sound features and integrating multidimensional information. Evidence shows that cortical microcircuits in Layers 2/3 of A1 selectively integrate spectrotemporal information to create networks that respond to complex sounds in a species-specific manner, but many fundamental details about this neurocomputational process remain unknown. The bat auditory system is primarily adapted to analyze the echoes of their own calls for information about the identity and location of targets. Assuming bat A1 follows typical mammalian organization, we hypothesized that compared to Layer 4, neurons in Layers 2 and 3 would exhibit greater selectivity for complex features used in biosonar target discrimination, namely rapid amplitude modulations embe
