Sentence examples for deactivation of the task from inspiring English sources

It has been found that reasoning about internal mental states is associated with activation of the default mode network (DMN) and deactivation of the task positive network (TPN); whereas reasoning about mechanical processes produces the opposite pattern.

Resting state fMRI studies furthermore show that this progressive increase in activation and functional connectivity in task-relevant brain networks is accompanied by progressively stronger deactivation of the task-anti-correlated default mode network [ 30].

The fMRI literature on resting state connectivity shows that this progressive age-associated increase in activation and inter-regional connectivity is associated with progressively stronger deactivation of the task-anti-correlated resting state network, both of which are associated with more mature performance [ 30].

To disentangle whether the differences between siblings and controls observed were due to an increase of the task-positive network or an impaired deactivation of the task-negative network in siblings relative to controls, we masked the results either by group effects of the task-positive ('2 minus 0 Back') or task-negative network ('0 minus 2 Back') for controls (Fig. 1E and F).

As a first result of our study, we confirm that deactivation of the DMN during task performance increases with task difficulty, which is in line with other studies investigating the DMN in working-memory paradigms (e.g. [21] [23]).

Because of the relatively large area encompassed by these anatomical regions, "functional" ROI masks were generated by identifying voxels within each anatomical region that exhibited supra-threshold activation or deactivation in any of the task conditions.

We addressed the following questions: i. Can the modulatory effect of cognitive load on the deactivation of the DMN during task performance be confirmed?

Adolescents showed greater relative activation of the task positive attention network and deactivation in the task negative network after chronic sleep restriction than when well-rested.

In this regard, studies that reported a correlation between task-related deactivation of the DMN and lower frequency of task-unrelated thoughts [16], [24], might reflect a functional representation of this idea.

With the onset of a task requiring focused attention, deactivation of the DMN is typically accompanied by activations in task-specific brain areas required for successful task performance [16].

The lack of deactivation of mPFC is consistent with previous reports of ADHD-related reductions in task-related deactivation of the BOLD response in DM regions during a working memory [21] and Stroop task [22].
