Response properties of neurons in the core of the central nucleus of the inferior colliculus of the barn owl

The central nucleus of the inferior colliculus (ICC) is particularly important for the processing of interaural time differences (ITDs). In the barn owl, neuronal best frequencies in a subnucleus of the ICC, the ICCcore, span the animal's entire hearing range (≈ 200–10 000 Hz). This means that low‐frequency ITD‐sensitive ICCcore neurons in the owl can be directly compared to ITD‐sensitive mammalian ICC neurons with similar best frequencies as well as to the high‐frequency ITD‐sensitive neurons usually studied in owls. This report represents a first attempt to systematically describe important physiological properties of ICCcore neurons in the barn owl, with particular attention to the low‐frequency region (
