Integration of sound and self-motion in human auditory cortex

在一系列的三个心理生理实验中，本项目研究了声音和自我运动的整合。在第一个实验中，我们测试了水平声音运动的两种不同线索，即听觉时间和水平差异，是单独处理还是在人类听觉皮层中以综合的方式处理。利用脑电图（EEG），我们观察到这两种信号在人的听觉皮层中主要是独立加工的。第二个实验测试的是手指运动引起的声音运动是否会减弱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.
