Segregated task-specific activations were demonstrated within the ventrolateral frontal, mid-temporal and inferior parietal areas.
Xgrid is targeted towards time consuming computations that can be easily segregated into smaller tasks, sometimes called embarrassingly parallel tasks.
At what times do networks segregate for task processing, and at what time scales does integration of information occur via changes in functional connectivity?
To analyze EEG correlates of cued attention task, we segregated the EEG signal in two segments.
In other words, targets (i.e., elements on the screen to which endogenous attention must be directed to accomplish the task) and distractors (i.e., elements on the screen that are irrelevant to the task) are physically segregated and appear at the same time.
In the current task, response control was studied using a fully counterbalanced design in which blocks with a low frequency of no-go cues (75% go, 25% no-go) were alternated with blocks with a low frequency of go cues (25% go, 75% no-go); see also "Segregating attention from response control when performing a motor inhibition task: Segregating attention from response control" [1].
All the regions in the final pool of task- and task × lexicality- sensitive regions were therefore segregated, based on BOLD responses, using hierarchical clustering.
Thus, this study was designed to examine overlapping versus segregated brain activations associated with three fundamental language tasks, orthography, phonology and semantics performed by the same subjects during a single experimental session.
Specifically, attention usually entails both the selection of task relevant and the corresponding suppression of task irrelevant information and can also be segregated according to the perceptual domain of interest.
Within the inferior frontal cortex (Broca's regional complex), segregated activations were seen for the semantic and phonological tasks.
