Cortical activation patterns during the n-back task in the sitting and cycling conditions. (A) F-map of oxy-Hb concentrations reflecting the main effect of the experimental condition. The significant main effect of the experimental condition between sitting and cycling conditions can be seen in the bilateral FPA, DLPFC, and r-MC (p < 0.05, FDR-corrected) among the ten regions of interest. F-values are displayed according to the color bar. (B–F) The mean difference of oxy-Hb concentrations between 1-back and 2-back conditions in both the bilateral FPA, DLPFC, and r-MC for sitting and cycling conditions.
