Answer 1

Neurogenesis

As recently as two decades ago, scientists believed we were born with all the neurons we would ever have. But the discovery of neurogenesis occurring in certain brain areas in monkeys gave rise to the hope that someday scientists will be able to induce the adult human brain to heal itself.

Neurogenesis is the process by which new neurons are created and developed in the brain. The new neurons are created by neural stem cells and it happens in almost all species of animals. Neurogenesis is effectual during embryonic development and completely through adult life in different organisms.
