no, think of what factors which determines the total number of nerve cells we have in our brain, the answer will be genetic and environment. our genetic pre-set the number of our brain nerve cells, a bigger brain does not necessary mean more nerve cells because the extra space can be filled with more fat tissue or fluid, our genetic make up is responsible for the skeleton for the development of our brain, some people might have a brain with more and some people less, people with the same brain size can have different number of nerve cell because the density can vary for example one person has 85% nerve cell, 10% fat, 5% fibers and the other person has 83% nerve cell, 12% fat and 5% fibers, but the same brain size. the other factor is the environment, for idential twins, their genetic make up is exactly the same, but they can still have different number of nerve cells in their brain, this is because our neurons are dying every second, and the rate of death varies from individual to individaul , stress could cause out brain cells to die faster, or alzhemers patients have their brain cell dying in very fast rate at late stage, overall the answer is no.

the subject remember of strategies cellular regeneration continues to be being debated in the scientific community. Neuroscience dogma says the cells interior of your disturbing device do no longer regenerate - you're born with each and every of the strategies cells to final your life time. contemporary looking, notwithstanding, exhibits that they might and do regenerate. it is unquestionably incorrect to declare that it takes 7-8 years for all your cells on your physique to be renewed. Cells interior of a few organ continuously regenerate in as low as 3-5 days. as an occasion, you're continuously laying off epidermis cells. There are different cells that only regenerate whilst they are injured. as an occasion, in case you donate 0.5 of your liver, it relatively is going to regenerate itself in 8 months. And there are cells that don't regenerate in any respect. as an occasion, your spinal twine won't regrow if severed.

No. It varies by several percent. But there doesn't seem to be any strong correlation between how many brain cells a person has and how intelligent they are.
