Figure 4. BOLD timecourses of activation from Broca's area from adults (blue) and children (red) from the video series.
The timecourses are averaged across the Broca's area voxels from Figure 2B. Percent signal change is calculated relative to the mean amplitude of the timecourse (the zero ordinate represents mean amplitude). The yellow bars indicate time periods where numerical information was presented in the video and the gray bars represent non-numerical video segments.
