aExcluded from the original HYPO group were two children with unacceptable scans and two whose mothers’ TSH values were in the normal range throughout pregnancy.
bTalairach coordinates (x, y, z) provide a three-dimensional atlas system that serves to map locations of specific brain structures; the x-coordinate indicates location in the right (positive)/left (negative) direction, y indicates anterior (positive)/posterior (negative) direction, and z signifies superior (positive)/interior (negative) direction.
cShown as red tones in Figure 1 to denote Control > HYPO, as per heat bars.
dShown as blue tones in Figure 1 to denote Control < HYPO.
