Flexible behavior depends on our ability to cope with distracting stimuli that can interfere the attainment of goals. Emotional distracters be particularly disruptive goal-oriented behavior, but neural systems through which these detrimental effects are mediated not known. We used event-related functional magnetic resonance imaging investigate effect emotional and nonemotional a delayed-response working memory (WM) task. As expected, this task evoked robust activity during delay period in...
The memory-enhancing effect of emotion can be powerful and long-lasting. Most studies investigating the neural bases this phenomenon have focused on encoding early consolidation processes, hence little is known regarding contribution retrieval particularly after lengthy retention intervals. To address issue, we used event-related functional MRI to measure activity during emotional neutral pictures a interval 1 yr. Retrieval for was separately analyzed successfully (hits) vs. unsuccessfully...
Abstract Functional neuroimaging studies of episodic memory retrieval generally measure brain activity while participants remember items encountered in the laboratory (“controlled condition”) or events from their own life (“open autobiographical condition”). Differences activation between these conditions may reflect differences processes, remoteness, emotional content, success, self-referential processing, visual/spatial memory, and recollection. To clarify nature differences, a functional...
According to the consolidation hypothesis, enhanced memory for emotional information reflects modulatory effect of amygdala on medial temporal lobe (MTL) system during consolidation. Although there is evidence that amygdala–MTL connectivity enhances stimuli, it remains unclear whether this enhancement increases over time, as processes unfold. To investigate this, we used functional magnetic resonance imaging measure encoding activity predicting emotionally negative and neutral pictures after...
Aging is associated with preserved enhancement of emotional memory, as well age-related reductions in memory for negative stimuli, but the neural networks underlying such alterations are not clear. We used a subsequent-memory paradigm to identify brain activity predicting enhanced young and older adults. Activity amygdala predicted greater stimuli than neutral across age groups, finding consistent an overall memory. However, adults recruited anterior regions less posterior general that were...
We determined if sleep deprivation would amplify the effect of negative emotional distracters on working memory. A crossover design involving 2 functional neuroimaging scans conducted at least one week apart. One scan followed a normal night and other 24 h deprivation. Scanning order was counterbalanced across subjects. The study took place in research laboratory. young, healthy volunteers with no history any sleep, psychiatric, or neurologic disorders. N/A Study participants were scanned...
The role of inferior frontal cortex in coping with emotional distracters presented concurrently a working memory task was investigated using event-related functional magnetic resonance imaging. study yielded two main findings: (i) processing associated enhanced coupling between the amygdala and (ii) showed left-lateralized activation pattern discriminating successful from unsuccessful trials presence distraction. These findings provide evidence that distraction entails interactions brain...
