The owl's cochlear nuclei process different sound localization cues.
This paper discusses how the barn owl's brain stem auditory pathway is divided into two physiologically and anatomically segregated channels for separate processing of interaural phase and intensity cues for sound localization. The paper also points out the power of the "downstream" approach by which the emergence of a higher-order neuron's stimulus selectivity can be traced through lower-order stations.
