Myelination and maturation occur in sequence, proceeding from the BRAIN STEM and CEREBELLUM to the FRONTAL CORTEX

Explanation:

Myelination is the process of coating the axons of every neurons with myelin (a fat coating) in order to protect the neurons and effectively conduct impulses.

Myelination begins before birth and is not completed until adolescence.

The process moves from back to the front or from the brain stem to the frontal cortex.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
