Abstract

Cullen et al. show that mature brain cells, called oligodendrocytes, undergo ultrastructural changes during learning. They lengthen the nodes of Ranvier and compress the periaxonal space to speed up action potential conduction. They also report that faster information transfer speeds correlate with greater skill acquisition during learning.
