In this way we could identify separate brain regions for task preparation and task performance, if they exist.
Our results showed that the frontal parietal network for spatial response selection activated both during task preparation as well as during task performance.
To examine the effects of a structured exercise program implemented during school break-time on working memory maintenance and neurophysiological indices of task preparation processes in adolescents.
The current findings suggest that physical fitness, but not an acute bout of aerobic exercise enhances cognitive processing by increasing attentional allocation to stimulus encoding during task preparation.
The participants in this condition were not provided with any guidance for task preparation, however, they were asked to write their notes on separate pieces of paper and these notes were taken away before they began completing the task.
Results indicate that higher-fit individuals show significantly greater CNV amplitudes, reflecting enhanced task preparation processes, as well as decreased amplitudes in N2, indexing more efficient executive control processes.
These findings indicate that, during task preparation, the activation pattern in currently task-relevant posterior brain regions is shaped by residual activation as well as preparatory modulation prior to the onset of the critical stimulus, even without participants being instructed to imagine the stimulus.
To investigate the role of posterior brain regions related to task-relevant stimulus processing in task preparation, we used a cued task-switching paradigm in which a pre-cue informed participants about the upcoming task on a trial: face discrimination or number comparison.
To elucidate mechanisms underlying the beneficial effects of physical fitness and acute exercise, behavioral and electrophysiological indices of task preparation and response inhibition as a part of executive functions were assessed in a modified version of an Eriksen flanker task subsequent to an acute bout of aerobic exercise and a period of rest, respectively.
This is generally consistent with the view that, during motor task preparation and/or execution the left, motor-dominant hemisphere (in right handed subjects) has a stronger influence on the right, motor non-dominant hemisphere than vice versa [18], [44].
Using EEG measures additionally enabled us to dissociate 2 distinct levels of task preparation.
