In contrast to several other mental retardation syndromes, the neuropsychology of Down Syndrome is relatively unexplored. The proposed research will fills gap in existing knowledge by testing the functional status of three neural systems particularly at risk in DS: the prefrontal cortex, hippocampus, and cerebellum. We will examine these three neuropsychological domains in a cross-sectional study of two age cohorts of individuals with DS (n=36 each) compared to two control groups, 1) younger normally developing children matched on MA, and 2) CA and MA matched children with non-DS mental retardation. Our component will provide a target phenotype for our colleagues working with mouse models, which will help them isolate the specific genetic determinants of the neural bases of this form of mental retardation.

与其他几种智力障碍综合症相反， 唐氏综合症的神经心理学相对尚未探索。提议 研究将通过测试功能来填补现有知识的空白 三个神经系统的状态，尤其是DS风险：前额叶 皮质，海马和小脑。我们将检查这三个 两个年龄群的横断面研究中的神经心理领域 与两个对照组相比，Ds（每个= 36）的个体1） 年轻的通常在MA上匹配的儿童以及2）CA和MA 匹配非DS智力低下的儿童。我们的组件会 为与鼠标模型一起工作的同事提供目标表型， 这将帮助他们隔离 这种形式的智力智能基础。
