As the morphological and physiological phenotypes of adult-born cells change markedly as they mature, they may have distinct roles at different stages following integration into hippocampal circuits. Adult-born dentate granule cells (DGCs) extend dendrites receive functional input from the existing ...

In addition, the nervous system helps maintain homeostasis. A stimulus is any change or signal in the environment that can make ...
