The hemispheric differences in neurotransmitter receptor/transporter density reflect the left–right differences in cortical thinning during adolescence. Negative values of hemispheric differences in cortical thinning mean more thinning in the right vs. left hemisphere during adolescence. Similarly, negative values of hemispheric (L-R) differences in density mean denser receptors/transporters in the right vs. left hemisphere. Regions that have a higher density of neurotransmitter receptors/transporters in the right (vs. left) showed more thinning in the right (vs. left) hemisphere. The results are projected onto a right-hemispheric template since more regions are right-dominant in thinning and the density of neurotransmitter receptors.
