Your mother always told you that you if you loose your brain cells to too much booze, then they won’t ever grow back.
Contrary to this popular belief, scientists have found that baby neurons in rat brains can develop and form new, functional connections within established neuron networks. To see this “neurogensis” in action, a stain was introduced into the brain that would only make dividing cells glow. Younger neurons undergoing cell division appeared a distinctive fluorescent color, while the older, non-dividing neurons remained in the dark.
Of course, it is still an assumption that this phenomena occurs in humans as well. However, it is anticipated that by gaining an understanding of how neurogenesis works, scientists can develop therapeutic methods to help reverse degenerative conditions like Alzheimer’s disease.
