仓鸮可以使用包含在视顶盖或听觉前脑中的听觉空间图来定位声源。听觉丘脑，卵核（N.Ov），位于这两个听觉区域之间，它的失活排除了使用听觉前脑的声音定位。我们研究了N.Ov的输入来源以及它们在核内的终止模式。我们还研究了单个神经元内的N.Ov的音调刺激和声音定位线索的反应。传入N.Ov起源于位于下丘中央核的外侧壳，核心和内侧壳分区内的神经元的扩散人口。额外的传入来自同侧外侧丘系腹侧核。下丘外核和视顶盖均未向N.Ov提供传入纤维。N.Ov的音调结构为高频位于背侧，低频位于腹侧。虽然N.Ov的神经元对定位线索作出反应，但与顶盖通路相反，这些线索在核内没有明显的地形图。然而，几乎所有可能的类型的双耳响应声音定位线索的代表。这些结果表明，在丘脑-端脑听觉通路，声音定位是subserved的非地形表示的听觉空间。
Barn owls can localize a sound source using either the map of auditory space contained in the optic tectum or the auditory forebrain. The auditory thalamus, nucleus ovoidalis (N.Ov), is situated between these two auditory areas, and its inactivation precludes the use of the auditory forebrain for sound localization. We examined the sources of inputs to the N.Ov as well as their patterns of termination within the nucleus. We also examined the response of single neurons within the N.Ov to tonal stimuli and sound localization cues. Afferents to the N.Ov originated with a diffuse population of neurons located bilaterally within the lateral shell, core, and medial shell subdivisions of the central nucleus of the inferior colliculus. Additional afferent input originated from the ipsilateral ventral nucleus of the lateral lemniscus. No afferent input was provided to the N.Ov from the external nucleus of the inferior colliculus or the optic tectum. The N.Ov was tonotopically organized with high frequencies represented dorsally and low frequencies ventrally. Although neurons in the N.Ov responded to localization cues, there was no apparent topographic mapping of these cues within the nucleus, in contrast to the tectal pathway. However, nearly all possible types of binaural response to sound localization cues were represented. These findings suggest that in the thalamo-telencephalic auditory pathway, sound localization is subserved by a nontopographic representation of auditory space.
