Neurophysiology of “Working Memory” Functional magnetic resonance imaging in adults and 13‐year‐old children Isolate activity during cue, delay, distraction, and response selection Adults were more accurate and less distractible than children Activity in the middle frontal gyrus and intraparietal cortex was stronger in adults than in children during the delay, when information was maintained in working memory Distraction during the delay evoked activation in parietal and occipital cortices in both adults and children However, distraction activated frontal cortex only in children Olesen et al., Cerebral Cortex 2007;17:1047‐54
