The work presents experimental data on certain changes in electrical responses of the auditory system's midbrain centre in a contraphasic binaural presentation of sound impulse series. Neuronal cortical activity is selective in respect to dynamic interaural changes of signals' phasic spectre which may serve as a basis for the mechanisms of localising a moving source of sound. Human auditory evoked potentials reveal a manifestation of memorizing the auditory image movement direction as shown by appearance of stimuli deviant from standard mismatch negativity.
这项研究展示了在声音脉冲序列的对侧双耳呈现中，听觉系统中脑中枢电反应某些变化的实验数据。神经元皮层活动对信号相位频谱的动态双耳变化具有选择性，这可能是声音移动源定位机制的基础。人类听觉诱发电位显示出对听觉图像运动方向的记忆表现，这表现为与标准失配负波不同的刺激出现。
