Neurogenesis-An Overview

Abstract

Neurogenesis is a phenomenon that involves the formation of new neurons in the brain by neural stem cells (NSCs). Investigators have confirmed that neurogenesis occurs in discrete parts of the adult brain as opposed to the embryos [1]. However, this was not the case long time back. Researchers have always been interested in learning if humans or other large organisms could show regenerative properties like the one seen in specific small organisms which can regrow different parts of their own bodies [2]. If possible, this would lead to a new avenue in therapeutics as more scientists would try to stimulate regeneration to deal with injury or any harmful stimuli. Like mentioned previously, researchers were not convinced with this approach and deemed that there is no possibility of adult neurogenesis [3].
