In the last few years, Functional Magnetic Resonance Imaging (fMRI) has been widely accepted as an effective tool for mapping brain activities in both the neurosensorial and the cognitive field. The present work aims to assess the possibility of using fMRI methods to perform a non-invasive evaluation of the human auditory function. To this end the cortical response to different non speech stimuli (pure tones, pulsed tones) was examined for ten subjects with no audiological impairment. Our findings point out some remarkable differences in both the spatial and the temporal features of the primary auditory cortex response to pulsed tones and to pure tones.
在过去几年中，功能磁共振成像（fMRI）已被广泛认可为一种在神经感觉和认知领域绘制大脑活动的有效工具。本研究旨在评估使用fMRI方法对人类听觉功能进行无创评估的可能性。为此，对10名无听力障碍的受试者检查了其对不同非语音刺激（纯音、脉冲音）的皮层反应。我们的研究结果指出，初级听觉皮层对脉冲音和纯音反应的空间和时间特征存在一些显著差异。
