axons, glial cells, dendrites ?

[raden]

Neurons stop reproducing after infancy. But axons, dendrites, and
glial cells--which provide electrochemical connections between
neurons--keep growing as long as we keep learning. These
interconnections are far more important to intelligence than the
number of neurons in our brain

Is there any way to increase axons, glial cells and dendrites ?

Will be apreciated.
