Low-demand network activity may reflect task- and performance monitoring that minimizes executive requirements for guidance of behavior.
SA patients show fluctuating semantic performance that is highly sensitive to the executive requirements of semantic tasks (Jefferies and Lambon Ralph 2006; Jefferies et al. 2007, 2008; Noonan et al. 2009; Corbett et al. 2009a).
These patients are highly sensitive to the executive requirements of semantic tasks—for example, they have difficulty retrieving the subordinate meanings of ambiguous words and struggle to reject highly associated distractor words in synonym judgment (Noonan et al. 2009).
These brain areas play an established role in the "multiple-demand" system, which mediates all tasks of high executive requirements irrespective of domain (Owen et al. 2000; Duncan 2006, 2010).
He was dismissive of the executive certification requirement, saying, "I never really thought that this was as momentous, important an event as some would have liked it to be".
Finally, the executive stability requirement guarantees preservation of function in the face of perturbations.
Expect the weekend to also produce some testy discussions on exchange-rate policies, executive compensation requirements for firms being rescued by governments and how much private enterprise governments should shoulder.
There were also no significant effects of TMS on the nonsemantic Navon tasks, irrespective of their executive control requirements.
Although parietal lobe is activated more by WM tasks involving spatial compared to visual information [9 15], this region is thought to play an important role in WM storage of both visual and spatial information [42,45], and superior parietal lobe is activated more by WM tasks which have greater executive control requirements [8].
