title: A representation of horizontal sound location in the inferior colliculus of the mustache bat (Pteronotus p. parnellii).
abstract: Binaurally sensitive E-I neurons in the inferior colliculus are topographically organized with respect to their sensitivity to interaural intensity disparities (IIDs). IID sensitivity dictates the azimuthal position of the medial border of a neuron's spatial receptive field. A sound moving along the azimuth will result in a change in the percentage of excited neurons as receptive field borders are crossed. Percent excitation within this population may provide a neural code for horizontal sound location.
