Fig. (3) Average activation maps of imagined navigation (Imag-Nav) and imagined rest (Imag-Rest). Activations were rendered with three statistical levels at F_(2,102) = 4.8, p<0.01; F_(2,102) = 7.4, p<0.001; and F_(2,102) = 10.1, p<0.0001; all masked by t₍₉₎ = 2.26, p<0.05, cluster corrected. See Table 1 for Talairach coordinates of ROI peaks. Abbreviations: LH/RH, left/right hemispheres; CS, central sulcus; PCS, postcentral sulcus; IPS, intraparietal sulcus; POS, parieto-occipital sulcus; PMd/PMv, dorsal/ventral premotor; SMG, supramarginal gyrus; aPCu, anterior precuneus. Other abbreviations as in text.
