Figure 4.

The hemispheric differences in the averaged hemodynamic responses within the ROIs. (A) The left ROI exhibited a larger response than the right ROI in the picture naming task (t = 5.3, p < 0.001). (B) The right ROI exhibited a larger response than the left ROI under the landmark condition in the landmark task (t = 6.6, p < 0.001). The red and black rectangle represents the duration of the instruction and task period, respectively. The error bar represents a 95% confidence interval. *p < 0.05, **p < 0.01, ***p < 0.001.
