“…Activation in left intraparietal sulcus during task switching has also been reported in several imaging studies, again very close to our own peak coordinates (Dreher and Grafman, 2003;Ruge et al, 2005;Rushworth et al, 2001; e.g. Sohn et al, 2000).…”

a b s t r a c t a r t i c l e i n f oWe frequently need to change our current occupation, an operation requiring additional effortful cognitive demands. Switching from one task to another may involve two distinct processes: inhibition of the previously relevant task-set, and initiation of a new one. Here we tested whether these two processes are underpinned by separate neural substrates, and whether they differ depending on the nature of the task and the emotional content of stimuli. We used functional magnetic resonance imaging in healthy human volunteers who categorize emotional faces according to three different judgment rules (color, gender, or emotional expression). Our paradigm allowed us to separate neural activity associated with inhibition and switching based on the sequence of the tasks required on successive trials. We found that the bilateral medial superior parietal lobule and left intraparietal sulcus showed consistent activation during switching regardless of the task. On the other hand, no common region was activated (or suppressed) as a consequence of inhibition across all tasks. Rather, task-specific effects were observed in brain regions that were more activated when switching to a particular task but less activated after inhibition of the same task. In addition, compared to other conditions, the emotional task elicited a similar switching cost but lower inhibition cost, accompanied by selective decrease in the anterior cingulate cortex when returning to this task shortly after inhibiting it. These results demonstrate that switching relies on domain-general processes mediated by postero-medial parietal areas, engaged across all tasks, but also provide novel evidence that task inhibition produces domain-specific decreases as a function of particular task demands, with only the latter inhibition component being modulated by emotional information.

“…Our main claim is that we do not see one neural region that is engaged by both perceptual and rule shifts. As this claim rests on a null result, however, we must interpret this result with due caution.We believe that the present results may bear on a current debate in the literature concerning the nature of task-switching with some arguing that the time taken to switch tasks reflects an active process of engaging the current task set (Rogers & Monsell, 1995;Meiran, 1996) while others argue that it reflects the time taken for the previous task set to decay (Altmann, 2003;Ruge et al, 2005). One could argue that a minimum requirement for a putative control structure would be a strong relationship between functional activity and successful performance.…”

“…For example, switching between classifying the location of a stimulus as either horizontal or vertical is referred to by some as set shifting (Smith, et al 2004;) and by some as task switching (Brass, et al, 2003;Ruge, et al, 2005). We use the most broad term "task switching" in this paper and discuss studies that examine the behavioral or neural consequences of a change in the goal or the relevant stimulus property regardless of whether it is referred to as a "set shift, "task switch", or "attention switch".…”

Shifting set about task switching: Behavioral and neural evidence for distinct forms of cognitive flexibility

2008

Task switching is an important aspect of cognitive control and understanding its underlying mechanisms is the focus of considerable research. In this paper, we contrast two different kinds of task switching paradigms and provide evidence that different cognitive mechanisms underlie switching behavior depending on whether the switch is between sets of rules (rule switch) or sets of features presented simultaneously (perceptual switch). In two experiments, we demonstrate that behavioral effects (Experiment 1) and neural recruitment (Experiment 2) vary with the type of switch performed. While perceptual switch costs occurred when the alternative feature set was physically present, rule switch costs were observed even in their absence. Rule switching was also characterized by larger target repetition effects and by greater engagement of the dorsolateral prefrontal cortex. In contrast, perceptual switching was associated with greater recruitment of the parietal cortex. These results provide strong evidence for multiple forms of switching and suggest the limitations of generalizing results across shift types. KeywordsExecutive function; cognitive control; dorsolateral prefrontal cortex; superior parietal cortex; fMRI The ability to switch tasks rapidly is important for responding flexibly in a changing environment (Miller & Cohen, 2001). Both behavioral and neuroscientific investigators have sought to understand how people disengage from one task in order to undertake another (see Monsell, 2003, for a review). In this set of experiments, we seek to understand the behavioral and neural consequences associated with different forms of task switching. Specifically, we examine whether there are qualitative differences in the cognitive mechanisms used to switch between tasks that require the reorienting of visuospatial attention (e.g., to what or where should I attend?) and switches that involve the ability to deal with changing goal-related information such as rules (e.g., what should I do?). We propose that the "task" used to investigate task switching (or "set" in set shifting) has important implications for understanding the nature of © 2008 Elsevier Ltd.

“…Interestingly, we also found a marginally significant interaction between choice type and prime-response compatibility in the right SG, indicating that this region might be involved more during free choices than during cued choices, mirroring the response time pattern. The SG, which is part of the inferior parietal lobe (IPL), has been associated with making voluntary choices (Forstmann et al, 2006), and is thought to be part of a fronto-parietal action control network (Ruge, Brass, Koch, Rubin, Meiran, & von Cramon, 2005;Forstmann et al, 2006). As stated in the results section, however, this result should be interpreted with caution, because the interaction in this particular ROI is not independent of the definition of the ROI.…”

Influences of unconscious priming on voluntary actions: Role of the rostral cingulate zone

et al. 2016

The ability to make voluntary, free choices is fundamental to what it means to be human. A key brain region that is involved in free choices is the rostral cingulate zone (RCZ), which is part of the medial frontal cortex. Previous research has shown that activity in this brain region can be modulated by bottom-up information while making free choices. The current study extends those findings, and shows, for the first time, that activation in the RCZ can also be modulated by subliminal information. We used a subliminal response priming paradigm to bias free and cued choices. We observed more activation in the RCZ when participants made a choice that went against the prime's suggestion, compared to when they chose according to the prime. This shows that the RCZ plays an important role in overcoming externally-triggered conflict between different response options, even when the stimuli triggering this conflict are not consciously perceived. Our results suggest that an important mechanism of endogenous action in the RCZ may therefore involve exerting an internally-generated action choice against conflicting influences, such as external sensory evidence. We further found that subliminal information also modulated activity in the anterior insula and the supramarginal gyrus.
