O cientista espanhol Ramón y Cajal e seus contemporâneos defendiam a idéia de que o sistema nervoso de indivíduos adultos fosse imutável, sem a possibilidade de que novos neurônios surgissem. No entanto, com o desenvolvimento recente de novas técnicas, foi possível confirmar a existência da neurogênese na fase adulta. Como a maior parte dos novos neurônios surge em uma estrutura crítica nas funções de memória, acredita-se que eles contribuam para o aprimoramento destas funções e não sejam apenas vestígios ontogenéticos. Essa breve revisão busca discutir algumas teorias e evidências experimentais a respeito da neurogênese e seu papel no sistema nervoso de indivíduos adultos.
