BACKGROUND
Studies related to plasticity and learning-related phenomena have primarily focused on higher-order processes of the auditory system, such as those in the auditory cortex and limited information is available on learning- and plasticity-related processes in the auditory brainstem.
DESIGN AND METHOD
A clinical electrophysiological test of speech-evoked ABR known as BioMARK has been developed to evaluate brainstem responses to speech sounds in children with language learning disorders. Fast ForWord (FFW) was used as an auditory intervention program in the current study and pre- intervention and post-intervention speech-evoked ABR (BioMARK) measures were compared in 2 school-aged children with auditory processing disorders (APD).
RESULTS AND CONCLUSIONS
Significant changes were noted from pre-intervention to post-intervention and reflect plasticity in the auditory brainstem's neural activity to speech stimuli.
背景
与可塑性和学习相关现象的研究主要集中在听觉系统的高阶过程，如听觉皮层中的过程，而关于听觉脑干中与学习和可塑性相关过程的信息有限。
设计与方法
已开发出一种名为BioMARK的言语诱发ABR临床电生理测试，以评估语言学习障碍儿童脑干对语音的反应。在本研究中，快速前进（FFW）被用作听觉干预计划，并对2名患有听觉处理障碍（APD）的学龄儿童干预前和干预后的言语诱发ABR（BioMARK）测量结果进行了比较。
结果与结论
干预前到干预后有显著变化，反映了听觉脑干神经活动对言语刺激的可塑性。
