Myelination is essentially complete by 8 years of age(that is to say for any added myeline there are corresponding losses), therefore this plasticity is not an option to target for COgn ehancement. There maybe some required nutrients that can enhance the quality of Myelin and enhance conduction. Which could could could provide benefits at the real high end.
Crono is correct, as an adult, increasing cell viability, NMDA plasticity and metabolism are the only options to increasing Cogn function. Grey matter is essential to learning, in the typical adult there is an 8th of the cortical grey matter thickness than at 5 years of age. There are methods to enhance this, Growth Factors for one, BDNF,GDNF,NGF
Curcumin has a real BDNF effect, there are more, depends how far you want to do
