Activations related to dual-tasking prior to training (pre-training session).

<p>Network of prefrontal activation in dual-task, with more emphasis on equation (80% Equation (80/20)) in <b>A</b> and <b>B</b>; equal division of attention (50% Equation (50/50)) in <b>C</b> and <b>D</b>; and more emphasis on detection (20% Equation (20/80)) in <b>E</b> and <b>F.</b> The threshold for display is P<0.001, uncorrected, 10 voxels. Coloured bar is representative of t scores mentioned in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0102710#pone-0102710-t005" target="_blank">Table 5</a>. “L” denotes the left side of the brain, while “R” denotes the right side.
