不同的地方可能有共同的特征,但由海马体中不同的CA3神经元群体编码。在这里,我们表明,化学或遗传抑制成年神经发生在海马损害这种人口为基础的编码相似(但不是不相似)的情况。这些数据提供了一个神经基础受损的空间歧视消融成人神经发生,并支持建议,成人神经发生调节模式分离过程中的海马体的效率。
Different places may share common features, but are coded by distinct populations of CA3 neurons in the hippocampus. Here we show that chemical or genetic suppression of adult neurogenesis in the hippocampus impairs this population-based coding of similar (but not dissimilar) contexts. These data provide a neural basis for impaired spatial discrimination following ablation of adult neurogenesis, and support the proposal that adult neurogenesis regulates the efficiency of a pattern separation process in the hippocampus.
