Explanation:

Neurogenesis (production of new neurons) in adults occurs in specific regions of the brain. The hippocampus and the sub - ventricular zone are two main areas where neural stem cells are present and can generate new neurons. Bones, skin layers, and the digestive tract do not have stem cells that produce new neurons.
