After 40 years of research, scientists have confirmed that persistent neurogenesis occurs in the adult mammalian brain. The obvious next question is: "Are the newly generated neurons functional?" If so, "What are the functions of these new neurons?" This volume intends to clarify both questions by providing the latest data available.
