Regular physical activity may improve brain function, both by increasing blood flow to the brain and stimulating the production of hormones and nervegrowthfactors involved in neurogenesis.
The second hypothesis is that nervegrowthfactors - which encourage new neural cell growth but which decrease with age - account for the drop in neurogenesis.
第二个假设是,神经生长因子-这将鼓励新的神经细胞的生长,但随着年龄的减少-帐户的下降,神经。

As one of the factors in the neurotrophin family, nervegrowth factor (NGF) is widely distributed in the central nervous system.
