We have intended to understand mechanisms of feature extraction and processing of sound information as activities of synapse and individual neuronal cells. Features of sounds such as time and intensity are important binaural cues for localizing the source Interaural time differences (ITDs) and interaural level differences (ILDs) are known extracted and processed in parallel by separate pathways in the brainstem auditory nuclei. ITD cues are small, and processing of that cue is optimized along the frequency axis by both morphological and physiological specializations. Moreover, we found that ITD and ILD cues are not processed independently but cooperatively to improve the detection of interaual differences. Thus, we have succeeded to understand some principal mechanism of auditory information processing in the brainstem nuclei.

我们的目的是了解机制的特征提取和处理的声音信息的活动的突触和个别神经元细胞。声音的特征，如时间和强度是用于定位源的重要双耳线索，耳间时间差（ITD）和耳间水平差（ILD）已知由脑干听觉核中的单独通路并行地提取和处理。ITD线索很小，并且通过形态学和生理学专业化沿着频率轴对该线索的处理进行了沿着优化。此外，我们发现，ITD和ILD线索不是独立处理，但合作，以提高检测跨性别差异。因此，我们已经成功地了解了脑干核团中听觉信息处理的一些主要机制。
