Figure 3.
Brain activity during dual tasks in relation to the baseline dual task. Areas showing significant (Z > 2.3, cluster corrected P < 0.05) activity in relation to the ASimpVSimp dual task (simultaneous speaker-gender and font-shade discrimination task) used as the baseline. Dual tasks including the (A) auditory phonological, (B) auditory spatial, and (C) auditory simple component tasks compared with the baseline dual task. Dual tasks including the visual phonological, visual spatial and visual simple component tasks compared with the baseline dual task are shown in top, middle and bottom rows, respectively. Brain activity during the ASimpVSimp dual task in relation to brain activity during the resting periods is shown in the right bottom corner. Cortical activations are superimposed from 10 mm under the cortex on surface of rendered brain images.
