The phrase "active task" is correct and usable in written English.
It can be used to refer to a task that is currently in progress or being worked on.
Example: "Please focus on the active task at hand before moving on to the next one."
Alternatives: "ongoing task" or "current task".
However, the role of passive exposure time to emotional signals in the modulation of amygdala activity during active task performance has not been examined.
Structural magnetic resonance imaging (MRI) is used for assessment of white and gray-matter integrity and cerebrovascular perfusion, and functional MRI maps brain activation during rest and active task conditions.
In the active task the participant actively moved the trunk from the starting position until a command to stop was given.
These regions show more activity during passive baseline than active task conditions [1], [2], [3] and also show strong coherence during rest [4], [5], [6].
Many studies suggest sustained DMN activity in rest compared to active task performance.
This design allowed us to examine how active task engagement would affect amygdala activation during exposure to the emotionally salient stimulus (i.e., anticipation of pain, in this case).
In the present study we used a rs-fMRI paradigm to investigate brain activity in (C APD (and not an active task).
Additionally, we showed that passive language fMRI produced more left-lateralized activation in TPG (LI = +0.45) compared to the active task; with similarly robust left-lateralized IFG (LI = +0.24) activations using the passive task.
This is further underpinned by the fact that the presence of distracters changed activity even in trials where subjects were not engaged in an active task.
Specifically, diverting attentional resources away from emotional, fear-arousing stimuli with an active task leads to a reduction of emotional responses and brain activation within the amygdala and related circuitry [8], [9], [10], [11], [12], [13], [14], [15], [16].
