Gray matter volumetric changes with a challenging adaptive cognitive training program based on the dual n-back task

Here we analyze changes in gray matter volumes following a challenging adaptive cognitive training program based on the n-back task. Twenty-six young healthy women completed twenty-four cognitive training sessions across twelve weeks showing substantial average improvements in cognitive performance. High-resolution MRI scans were obtained before and after training. Brain images of the training group were compared to those of a control group by...
