AUDITORY EVOKED BRAIN POTENTIALS IN NEUROLOGICAL DISEASE

我们计划研究听觉诱发电位（AEPs）， 临床神经系统疾病和动物实验来定义 这些电位产生的神经机制， 它们在大脑功能紊乱中的应用 我们尤其 将在实验动物中研究细胞和神经的作用 产生远场听觉脑干成分的纤维 使用特定的损伤方法和在体外模型系统中 利用神经纤维穿过 不同的体积和阻抗。 长潜伏期AEP相关 到单词和音调的编码以及它们随后的 记忆将在正常受试者和患者中进行研究 与局灶性半球病变，以确定神经相关的 语言处理和听觉记忆。 的定义 将定义与声音定位相关的双耳过程 中、长潜伏期AEPs的双耳诱发电位 互动组件和相关的几个心理声学 在正常受试者，神经系统病变患者， 以及在成熟期的儿童。

We plan to study auditory evoked potentials (AEPs) in both clinical neurological disorders and animal experiments to define neural mechanisms of the generation of these potentials and their application to disordered brain function. In particular, we will study in experimental animals the role of cells and nerve fibers in generating far-field auditory brainstem components using specific lesion methods and in an in-vitro model system using nerve fibers passing between fluid compartments of different volumes and impedances. Long-latency AEPs related to the encoding of words and tones and their subsequent memorization will be studied in normal subjects and patients with focal hemispheric lesions to define neural correlates of language processing and auditory memory. The definition of binaural processes relevant for sound localization will be defined in middle and long-latency AEPs by the occurence of binaural interaction components and related to several psychoacoustic measures in normal subjects, patients with neurological lesions, and in children during maturation.
