DESCRIPTION (provided by applicant): We propose to examine the neural mechanisms of spatial hearing in the presence of acoustical reflections. The inferior colliculus in our animal model, the barn owl, contains a topographic map of auditory space the activity across which represents the spatial relationships of sound-sources in the environment. We will reconstruct the neural image evoked by a sound from an actively-emitting source and a delayed reflection. The behavioral consequences of the owls using this image are predicted and tested in parallel behavioral experiments.

描述（由申请人提供）：我们建议检查存在声反射的空间听觉的神经机制。我们的动物模型仓鸮的下丘包含听觉空间的地形图，其活动代表环境中声源的空间关系。我们将重建由主动发射源和延迟反射的声音引起的神经图像。猫头鹰使用此图像的行为后果的预测和测试在平行的行为实验。
