Table 1.
Atlas locations of the functional near-infrared spectroscopy (fNIRS) channels across the group of infants that were assigned to (a) the 4.5-month-old age-appropriate template and (b) the 6-month-old age-appropriate template. The label of the channel is followed by (%) of infants with this region. Regions are reported when the number of allocated infants of the group. The italicized labels are those with a differing majority lobar or macro-anatomical region between the two groups of infants (4.5- versus 6-month-olds). Note that the groups match if you allow any channel label where the group scores (i.e., channel 9: 4.5 months—superior temporal gyrus 44%, postcentral gyrus 36%; 6 months—superior temporal gyrus 37%, postcentral gyrus 53%).
