The large number of behavioral studies testing whether working memory training improves
performance on an untrained task have yielded inconclusive results. Moreover, some studies have
investigated the possible neural changes during the performance of untrained tasks after training. Here,
we studied the transfer from n-back training to the Paced Auditory Serial Addition Test (PASAT), two
diferent tasks that use the central executive system to maintain verbal stimuli. Participants completed
fMRI sessions at baseline, immediately after one week of training, and at the fve-week follow-up.
Although behavioral transfer efects were not obtained, training was associated with decreased
activation in the anterior dorsolateral prefrontal cortex (DLPFC; BA 9/46) while performing the PASAT
that remained stable fve weeks later. Consistent with our hypothesis, the changes in the anterior
DLFPC largely overlapped with the n-back task fMRI activations. In conclusion, working memory
training improves efciency in brain areas involved in the trained task that may afect untrained tasks,
specifcally in brain areas responsible for the same cognitive processes. [-]
