White matter and myelin plasticity
WHITE matter and Myelin plasticity
White matter plasticity is a recently described mechanism by which experience shapes brain structure and function during adulthood. This phenomenon was first described in adult humans with complex motor skill learning using whole brain non-invasive diffusion tensor imaging (DTI). We use magnetic resonance imaging (MRI) as a translational tool in conjunction with established cellular techniques and transgenic models to elucidate the underlying cellular mechanisms of white matter plasticity.
