Figure 1. Inter-subject correlation (ISC) increases with age in sensory regions and decreases with age in the PMC.

(a) Within-group ISC was computed for five distinct age groups, and a statistical comparison was performed between the Oldest and Youngest age groups. (b) The difference in ISC between the Youngest (5–8years) group and the Oldest (16–19years) group is displayed in significant parcels (q<0.05) on the cortical surface. ISCs for all age groups are plotted for four significant parcels, selected post hoc for illustration, along with the ISC difference between the Youngest and Oldest groups compared to the null distribution.

(a) Schematic illustration of the correlation for each parcel between subjects in the Youngest (5–8 years) and Oldest (16–19 years) groups. (b) ISC in parcels on the cortical surface.

Figure 1—figure supplement 2.

ISC is displayed separately in parcels across the cortical surface for subjects in the Youngest (5–8 years) and Oldest (16–19 years) groups. Both age groups show a similar pattern of ISC increasing from sensory to anterior regions.

Figure 1—figure supplement 3.

The “Oldest” age group (16–19 years) had only 40 subjects. All other age groups contained a sub-sample of 40 subjects whose gender distribution matched that of the Oldest group. The counts of male and female subjects are overlapping.
