An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium.
Since the initial discovery that the adult brain contains stem cells that generate new neurons, an important question in neurobiology has been whether or not this adult neurogenesis is functionally important.
This process, called adult neurogenesis, relies on vitamin D from your diet. An animal study, published in âHippocampusâ in 2012, found that vitamin D deficiency can prevent new brain cell growth, and also kills nerve stem cells -- cells with the potential to grow into mature brain cells.
