![عکس صفحه اول مقاله: Neural activation underlying cognitive control in the context of neutral and affectively charged pictures in children Neural activation underlying cognitive control in the context of neutral and affectively charged pictures in children](/preview/png/924411.png)
The neural correlates of cognitive control for typically developing 9-year-old children were examined using dense-array ERPs and estimates of cortical activation (LORETA) during a go/no-go task with two conditions: a neutral picture condition and an affectively charged picture condition. Activation was estimated for the entire cortex after which data were exported for four regions of interests (ROIs): ventrolateral prefrontal cortex (VLPFC), dorsal anterior cingulate cortex (dACC), dorsolateral prefrontal cortex (DLPFC), and orbitofrontal/ventromedial prefrontal cortex (OFC/VMPFC). Results revealed faster reaction times, greater N2 activation, and greater prefrontal activation for the affectively charged picture condition than the neutral picture condition. The findings are discussed in reference to the impact of affective stimuli on recruitment of specific brain regions involved in cognitive control.
► Typically-developing 9-year-old children played a go/no-go task.
► The N2—an ERP that measures cognitive control—was measured.
► Cortical activation underlying the N2 was estimated using the LORETA method.
► Results showed greater activity and faster response times in the context of emotion.
