This study attempted to demonstrate the extent of the
task load-dependent augmentation of brain activation and
the change of functional connectivity during the TSP.
Twenty healthy young adults (mean age: 22.80 }3.44, 9
males) participated in the study. The significant
activation was observed in the frontal and parietal
region and it was augmented as task load increased. In
addition, the functional connectivity was extended
depending on task load. These results were considered
that the network of these regions works as a central
executive, and it controls switch of attention, task-set
reconfiguration and inhibition during TSP.
