In a breakthrough that could provide new strategies for treating neuro-degenerative disease and memory loss scientists have identified a gene that prompts growth of new neurons in adults. Learning and memory are regulated by a region of the brain known as the hippocampus. New research from City of Hope National Medical Centre California has found that stimulating a specific gene could prompt growth of new neurons in this critical region leading to faster learning and better memories.
