目的研究人工耳蜗植入治疗先天性耳聋（n= 28）和正常听力儿童（n = 28）的皮层听觉诱发电位的表达方法我们利用一种新的脑电图范式，允许评估听觉反应的环境提出的讲话，并评估的贡献，同时视觉刺激对此活动。结果我们的研究结果显示，在80- 200-ms和200- 300-ms的时间窗口发生的听觉感觉和知觉事件相关的潜在成分的表达组的差异，与幅度的减少和更大的潜伏期差异CI使用儿童。相对于典型的听力儿童，电流源密度分析显示，在CI使用儿童并发视觉刺激静音反应，这表明皮质专业化和/或减少对听觉信息的反应，限制了检测之间的相互作用的感觉systems.ConclusionThese研究结果表明，即使在面对早期干预，使用CI的儿童可能会表现出听觉和多感觉处理的发展中断。
PurposeThis research examined the expression of cortical auditory evoked potentials in a cohort of children who received cochlear implants (CIs) for treatment of congenital deafness (n= 28) and typically hearing controls (n= 28).MethodWe make use of a novel electroencephalography paradigm that permits the assessment of auditory responses to ambiently presented speech and evaluates the contributions of concurrent visual stimulation on this activity.ResultsOur findings show group differences in the expression of auditory sensory and perceptual event-related potential components occurring in 80- to 200-ms and 200- to 300-ms time windows, with reductions in amplitude and a greater latency difference for CI-using children. Relative to typically hearing children, current source density analysis showed muted responses to concurrent visual stimulation in CI-using children, suggesting less cortical specialization and/or reduced responsiveness to auditory information that limits the detection of the interaction between sensory systems.ConclusionThese findings indicate that even in the face of early interventions, CI-using children may exhibit disruptions in the development of auditory and multisensory processing.
