"In the adult hippocampus, a brain region that is important for memory, new neurons are generated continuously. A study now shows that these newly generated neurons are preferentially activated during learning and recall of new memories."Young and excitable: new neurons in memory networks"

" A single, socially stressful situation can kill off new nerve cells in the brain region that processes learning, memory, and emotion, and possibly contribute to depression, new animal research shows.Stress and Neurogenesis in the Rat
Researchers found that in young rats, the stress of encountering aggressive, older rats did not stop the generation of new nerve cells-the first step in the process of neurogenesis. But stress did prevent the cells, located in the hippocampus, from surviving, leaving fewer new neurons for processing feelings and emotions."
