Integration of sound and self-motion in human auditory cortex

在一系列的三个心理生理学实验中，我们研究了声音和自我运动的整合。在第一个实验中，我们测试了两种不同的水平声音运动线索--耳间时间和水平差异--在人类听觉皮质中是独立处理的，还是以整合的方式处理的。利用脑电，我们主要观察到人类听觉皮层中这两个线索的独立加工。第二个实验测试了手指运动引起的声音运动是否衰减或影响随后的大脑反应。在第三个实验中，我们测试了头部和声源运动的整合。

In a series of three psychophysiological experiments, this project investigated the integration of sound and self motion.In a first experiment, we tested whether the two different cues for horizontal sound movement, interaural time and level differences, are processed independently or in an integrated manner in human auditory cortex. Using electroencephalography (EEG), we observed mainly independent processing of the two cues in human auditory cortex.The second experiment tested whether finger motion that elicits sound movement attenuates or influences the subsequent brain response. In a third experiment, we tested for integration of head and sound source motion.
