It was a report of a study on the use of neuroimaging in language learning. The study focused on the neural mechanisms underlying new language learning. It combined all neuroimaging techniques including MRI technique to investigate either brain activation, through task-based or resting-state fMRI, or brain structure such as gray matter structure or white matter connectivity to comprehensively investigate the neural correlates underlying new language learning in a cross-sectional sample. The key strength of this study was to focus on age-related as well as individual differences using an extensive behavioral testing battery, a behavioral and a neural fingerprint of every individual to determine how each subcomponent affects L2 learning at different ages.
