摘要
皮层听觉诱发电位(cortical auditory evoked potentials,CAEP)是大脑皮层接收声音刺激后产生的生物电反应,为客观评估听觉通路的功能,特别是中枢听觉处理能力,提供重要窗口。CAEP动态监测技术通过量化P1、N1、P2等核心参数,为人工耳蜗植入(CI)儿童术后的神经重塑与精准康复提供了关键评估手段。人工耳蜗植入后大脑听觉皮层的电生理变化标志着听觉功能的成熟与重组,双侧CI使用者呈现半球优势转移现象,揭示大脑跨模态重组机制,结合认知训练可显著提升特殊需要人群的言语识别率。然而,当前领域面临标准化体系缺失与个体差异干扰等瓶颈,未来需构建多中心数据库并融合神经影像技术,建立神经响应-行为表现-中枢机制多模态评估模式,推动康复策略向神经适配跃迁,全面赋能重度感音神经性聋人工耳蜗植入儿童的神经可塑性潜能。
CAEP is a bio-electric response generated by the cerebral cortex after receiving sound stimulation,providing an important window for us to objectively assess the function of the auditory pathway,especially the central auditory processing ability.The dynamic monitoring technology of CAEP quantifies core parameters such as P1,N1,and P2,offering a key assessment method for neural remodeling and precise rehabilitation after cochlear implantation(CI)in children.Research shows that the electrophysiological changes in the auditory cortex of the brain after cochlear implantation mark the maturation and reorganization of auditory function.Bilateral CI recipients exhibit a phenomenon of hemispheric dominance transfer,revealing the brain's cross-modal reorganization mechanism.Combined with cognitive training,it can significantly improve the speech recognition rate of special populations.However,the current field faces bottlenecks such as the lack of a standardized system and the interference of individual differences.In the future,it is necessary to build a multi-center database and integrate functional neuroimaging technology to establish a multimodal assessment model of"neural response-behavioral performance-central mechanism",promoting the leap of rehabilitation strategies to"neural adaptation"and fully empowering the neural plasticity potential of children with severe sensorineural hearing loss who have undergone cochlear implantation.
