> exercise has a positive impact on the creation of new neurons on the brain. The idea that we're born with a limited number of brain cells has been debunked.
I'm not being a typical HN'er, I am legitimately curious, do you have some good sources that describe this? My current understanding is that new neurons aren't so easily formed because your brain is actually so efficient, it will simply form new pathways between existing neurons to do the same thing it once did with lost or damaged neurons. Would like to know that this is incorrect or not.

That's what we have been taught at school.
Meanwhile we better understand neurogenesis, creation of nerves, and neuroplasticity, rewiring of nerves:
