Longevity is directly related to the maturity of the brain and its number of neurons.
It has long been thought that the maximum longevity of mammals is proportional to body mass. A recent study using a dataset of over 700 species including humans,
A recent study of more than 700 species, including man, shows that longevity is actually closely related to the number of brain neurons (1).
It seems that the longer it takes for the brain to mature, the longer the longevity.
These results put the brain at the centre of concerns for longevity and well-being throughout life.
Knowing that we are beginning to control brain aging, thanks in particular to the plasticity of the brain that makes its shaping possible, this discovery points to infinite hopes for anti-aging medicine.
