The biological system of the human body is absolutely amazing. The organic ensemble of fibers, nerve endings, tissues, and whatnot are so complicated and in the right situation, is completely capable of restoring itself. Most of it is due to the endocannabinoid system present in each and every mammal on the planet. The brain forms also part of this equation and the adult brain can produce new neurons. This process is called neurogenesis.
Neurogenesis mostly takes part in two parts of the brain. It takes place in the subventricular Zone (SVZ) and the subgranular zone (SGZ). Neurogenesis is vitally important in the adult brain as it regulates mood, brain health, and learning. Some psychiatric disorders are believed to be related to impaired neurogenesis.
