The Brain’s White Matter–Learning beyond Synapses

Recently scientists have been exploring part of the brain that has been relatively unexplored in learning–white matter, comprising half of the human brain.  Here new research is detecting cellular changes during learning that are entirely different from the synaptic changes between neurons in gray matter.  A new study shows that learning a new motor skill requires generation of new myelin, the electrical insulation on nerve axons.
