HEARING IN MICE AND CHICKENS

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 我们将继续研究细胞间和细胞内信号通路，导致神经元死亡（或生存）后，兴奋性突触输入到哺乳动物耳蜗核消除。在目前的赠款期间的一个主要举措是使用现代遗传分析方法，开始评估新生儿和成年动物的传入剥夺（一个关键时期）的小鼠耳蜗核的差异反应的生物学机制。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. We will continue investigating the intercellular and intracellular signaling pathways that lead to neuronal death (or survival) following the elimination of excitatory synaptic input to the mammalian cochlear nucleus. A major initiative during the current grant period has been to use modern genetic analysis methods to begin assessing the biological mechanisms underlying differential responses of neonatal and adult animals to afferent deprivation (a critical period) of the mouse cochlear nucleus.
