“…One important caveat regarding the left prefrontal dominance in set shifting revealed by our previous studies is that our modified WCST allowed subjects to respond slowly (Ϸ1,000 ms; see Fig. 2), unlike task switching paradigms in other studies where responses are made more rapidly, thus requiring inhibition of inappropriate responses implemented in the right prefrontal cortex (32)(33)(34)(35)(36). This task difference may account for the right frontal cortical involvement in task switching revealed by previous neuroimaging and neuropsychological studies (37,38).…”

Once one cognitive set dominates our behavior, it continues to influence subsequent behavior for a while even after a task to be performed is changed to another. Despite abundant knowledge of the inhibitory mechanisms that are recruited at the first trial after the change (the first inhibition trial), little is known about the inhibition of prolonged proactive interference from a previous set that lingers for several trials after the first inhibition trial. The present functional MRI study explored the neural mechanisms for inhibition of a previous set that were recruited after the first inhibition trial. A modified Wisconsin Card Sorting Test was used where ''dual-match stimuli'' were intermittently presented and allowed subjects to perform correctly based on previously appropriate, now inappropriate, responses. In response to the dualmatch stimulus at ''release'' trials presented after the first inhibition trials, the subjects were transiently exempted from inhibiting the prolonged previous set. As expected from the exempted inhibitory demands, significant reaction time decrease was revealed in the release trials. Consistent with the behavioral results, transient signal decrease time-locked to the release trials was revealed in the left anterior part of the superior frontal sulcus. Moreover, the anterior prefrontal region was not sensitive to the task change, which exhibited a marked contrast to the left posterior inferior prefrontal region that showed significant signal changes in both events. These results revealed multiple inhibitory mechanisms in the lateral prefrontal cortex that are recruited in different temporal contexts of the interference from a previous cognitive set.

“…This predicted difference in the timing of ACC activation has been confirmed in two separate EEG experiments [6,30] eye field, but not in ACC (but see [45]). Although these studies encourage the idea that conflict-related activation lies outside the ACC, it should be noted that they used a version of the go/no-go task, a task which has been clearly shown to engage the ACC in humans [16,18]. The reasons for this and other contradictions between human and monkey data are not fully understood.…”

“…In particular, it has been argued that attentional control of emotional distracters recruits rACC (Bishop et al, 2004;Etkin et al, 2006;Shin et al, 2001;Vuilleumier et al, 2001;Whalen et al, 1998). In contrast, attentional control of nonemotional distracters is thought to implicate dACC Carter et al 1995Carter et al , 2000Durston et al, 2002;MacDonald et al 2000;Menon et al, 2001). However, some studies report dACC rather than rACC activity in response to emotional distracters Davis et al, 2005;Haas et al, 2006;Mitchell et al, 2007).…”

Common regions of dorsal anterior cingulate and prefrontal–parietal cortices provide attentional control of distracters varying in emotionality and visibility

Top-down attentional control is necessary to ensure successful task performance in the presence of distracters. Lateral prefrontal cortex, parietal cortex and anterior cingulate cortex have been previously implicated in top-down attentional control. However, it is unclear whether these regions are engaged independent of distracter type or whether, as has been suggested for anterior cingulate cortex, different regions provide attentional control over emotional versus other forms of salient distracter. In the current task, subjects viewed targets that were preceded by distracters that varied in both emotionality and visibility. We found that behaviorally, the presence of preceding distracters significantly interfered with target judgment. At the neural level, increases in the emotional and visual saliency of distracters were both associated with increased activity in proximal regions of prefrontal, parietal and cingulate cortex. Moreover, a conjunction analysis indicated considerable overlap in the regions of prefrontal, parietal cortex and anterior cingulate cortex responding to distracters of increased emotionality and visibility.
