title: Complex models of white and gray matter integration following training.
abstract: For many tasks, an increase in competence is associated with faster response time. Voelker et al (this issue) explore the possible role of white matter reorganization as a mechanism underlying this relationship. With such a strong focus on this possible interpretation and the limits of current neuroimaging methods, the authors constrained their options to the point of only considering simplified models of how training might result in faster responses.
