感音神经性聋(sensorineural hearing loss,SNHL)是临床常见病和多发病,SNHL患者的听皮层能发生可塑性改变。近年来有关听觉的功能性磁共振成像(functional magnetic resonance i m-age,f MRI)研究报道日益增多,它可以反映听皮层功能状态和可塑性变化。本文综述了f MRI的工作原 Sensorineural hearing loss (SNHL) is a common clinical disease and frequently-occurring disease, SNHL patients with plastic deformation of the auditory cortex can occur. In recent years, there has been a growing number of reports about the functional magnetic resonance imaging (MRI) of the auditory sense, which can reflect the functional status and plasticity of the auditory cortex. This article reviews the working principle of f MRI
