INFANT COGNITIVE AND EEG DEVELOPMENT--BASIC PROCESSES

行为神经科学研究的最新进展已经允许 新皮层发育区之间关系的研究 和新兴的行为技能。 有证据表明， 虽然额叶皮层是大脑最后成熟的区域之一， 它可能在婴儿期发挥重要作用。 一 探索大脑/行为关系的潜在方法是测量 记录脑电活动（EEG）。最近的概念和 计算的进步导致了EEG的使用，作为衡量两者的一种手段， 区域发展和新兴的皮质-皮质连接。 本研究报告的目的是， 生活，基础研究的成熟脑电图及其关系， 具体的认知和语言行为。我们的目的是 认知和语言能力子集的发展变化 并将这些变化与EEG的特定参数联系起来。我们将 完成对48名婴儿的纵向研究，从14个月大开始， 每两个月（14、16、18、20、22和24个月）见一次 年龄）。在每个年龄段，我们将评估婴儿在任务中的表现， 开发正面和非正面调解能力。 另外我们 将评估婴儿自我调节技能的出现， 婴儿的父母完成标准化的语言评估 问卷 我们还将记录多导联EEG。 我们的目标包括 记录大脑电活动的变化-在第二年的 生活和调查脑电图变化与认知， 语言和自我调节的发展。加强对这些问题的了解 进程及其相互关系将提供一个重要的窗口， 来了解婴儿第二年的认知神经发育。 它也可能是重要的理解认知，语言， 非典型人群的自我调节发展。

Recent advances in behavioral neuroscience research have permitted investigation of the relations between developing areas of the neocortex and emerging behavioral skills. There is evidence which suggests that while the frontal cortex is among the last areas of the brain to mature, it may subserve important functions during the period of infancy. One potential method for exploring brain/behavior relations is the measurement of scalp recorded brain electrical activity (EEG). Recent conceptual and computational advances have led to the use of the EEG as a measure of both regional development and of the emerging cortico-cortical connections. The purpose of the present study is to extend, into the second year of life, basic research on the maturation of the EEG and its relation to specific cognitive and language behaviors. It is our intention to chart developmental changes in a subset of cognitive and language competencies and to relate these changes to specific parameters of the EEG. We will complete a longitudinal study of 48 infants, beginning at age 14 months, and will see them every two months (14, 16, 18, 20, 22, and 24 months of age). At each age we will assess infant performance on tasks designed to tap frontally and non-frontally mediated competencies. In addition, we will assess the emergence of infant self-regulatory skills and have parents of the infants complete a standardized language assessment questionnaire. We will also record multi-lead EEG. Our aims include documenting changes in brain electrical activity-across the second year of life and investigating the associations between EEG changes and cognitive, language, and self-regulatory development. Enhanced understanding of these processes and their interrelationships will provide an important window into understanding cognitive-neuro development in the second year of life. It may also be of importance in understanding the cognitive, language, and self-regulatory development of atypical populations.
