EVERYDAY SCIENCE

Detailed explanation-1: -Although the majority of neurons are already present in our brains by the time we are born, there is evidence to support that neurogenesis (the scientific word for the birth of neurons) is a lifelong process.

Detailed explanation-2: -Science has since discovered that neurons can actually regenerate using a really unique method if an area of the brain gets damaged – we call this method neurogenesis. What happens is the brain uses a secret supply of neural stem cells and transforms them into new neurons without using mitosis.

Detailed explanation-3: -In our sample of 50 brains from men, we find that IQ does not correlate with the number of brain cells in the human neocortex and was only weakly correlated to brain weight.

Detailed explanation-4: -The brain can produce new cells Neurogenesis is now accepted to be a process that occurs normally in the healthy adult brain, particularly in the hippocampus, which is important for a learning and spatial memory.
