概括
与正常听力同龄人相比,单侧耳植入器 (CI) 的儿童表现出口语工作记忆 (VWM) 的缺陷. 双边CI可以帮助聋子儿童接近正常的VWM基准值,EEG可能有助于诊断和康复.
科学领域:
- 神经科学是一个神经科学.
- 听力学 听力学是指听力学.
- 认知心理学 认知心理学
背景情况:
- 耳植入物 (CI) 在聋子儿童中恢复听力,但口头工作记忆 (VWM) 显著不同.
- 在CI用户中注意到VWM的缺陷,这是一个关键的执行功能,但根本原因尚不清楚.
研究的目的:
- 调查单边CI (UCI),双边CI (BCI) 和正常听力 (NH) 同龄儿童之间听觉和视觉VWM表现的脑电图 (EEG) 差异.
- 识别与VWM性能相关的EEG标记模式,跨不同难度级别和感官模式.
主要方法:
- 参与者 (UCI,BCI,NH儿童) 在听觉和视觉模式中执行了三级难度的n-back任务.
- 记录了EEG数据以分析大脑活动模式,重点关注太和玛频段.
主要成果:
- 在复杂的听觉任务中,UCI表现出正面低激活,与VWM性能相关,与NH同行和BCI不同.
- 与BCI和NH同行相比,UCI显示左半球和马带活动减少.
- 左半球的马振荡与NH和BCI组的听觉任务表现相关.
结论:
- 单边CI使用似乎不足以优化聋子儿童的听觉VWM.
- 双边IC使用可能使聋子儿童能够达到与NH儿童相比的VWM性能.
- 脑电图分析显示,对于诊断和康复聋子儿童的VWM缺陷有希望.

Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
