Dendritic extent in human CA2-3 hippocampal pyramidal neurons in normal aging and senile dementia. And, even if new neurons do appear later in life, scientists dont know if they could integrate into long-established brain networks or affect cognition. On the other hand, the branching of dendrites increases, and connections between distant brain areas strengthen. These data suggest a model of aging in the central nervous system in which one population of neurons dies and regresses and the other survives and grows.
