Contributions of Sound Localization Cues to Azimuth Tuning in the Auditory Midbrain.

ABSTRACT: Neurons in the central nucleus of the inferior colliculus exhibit spatial receptive fields due to underlying neural sensitivity to acoustic cues that covary with sound source location, including interaural time difference (ITD), interaural level difference (ILD), and spectral shape and average acoustic gain within each ear. While neural sensitivity to individual cues is generally known, what remains unknown is how individual cues contribute to a neuron's receptive field when all cues are combined and how these contributions vary with the neuron's characteristic frequency (CF). In the present study, broadband noise stimuli were presented to awake rabbits of both sexes in virtual acoustic space using the rabbit's own head-related transfer functions. Contributions of each cue to the azimuth t
