What is it?


Neurogenesis, or the birth of new neuronal cells, was thought to occur only in developing organisms. However, recent research has demonstrated that neurogenesis does indeed continue into and throughout adult life in both vertebrate and invertebrate organisms.

Examples of neurogenesis are found in the hippocampus of mammals, song control nuclei of birds and the olfactory pathway of rodents, insects and crustaceans.

On going neurogenesis is thought to be an important mechanism underlying neuronal plasticity, enabling organisms to adapt to environmental changes and influencing learning and memory throughout life.
