Analysis of embryonic brain wiring in C. elegans The goal of this project is to investigate how neural circuits are assembled in C. elegans embryos. We develop assays for an embryonic behavior (a sleep-like quiescent state) and for the neurons controlling this behavior. This embryonic sleep state is analogous to the quiescence that occurs during larval molts. We will determine if quiescence is triggered by cuticle synthesis. We will image synapse formation in embryos and will determine if sleep circuit development is controlled by heterochronic genes (which control larval skin development). We will also ask if circuit development is altered by mutations that prevent sleep or by those linked to Autism spectrum disorders (ASD). These Aims address basic questions about the genetic and physiological mechanisms controlling early brain development.

线虫胚胎脑连接的分析 这个项目的目标是研究线虫的神经回路是如何组装的。 胚胎。我们开发了胚胎行为(一种类似睡眠的静止状态)的分析方法 以及控制这一行为的神经元。这种胚胎睡眠状态类似于 幼虫蜕皮时的静止期。我们将确定静默是否 由角质层合成触发。我们将在胚胎中成像突触的形成，并将 确定睡眠回路发育是否受异时基因控制(哪种 控制幼虫皮肤发育)。我们还会问，电路的发展是否被 导致睡眠障碍或与自闭症谱系障碍(ASD)相关的突变。 这些目的是解决关于遗传和生理机制的基本问题。 控制早期大脑发育。
