Caption: On left is: Scatter plot of brain development indexes of 621 subjects calculated from MRI images, against the chronological ages of the subjects. The subjects with brain development indexes outside the 90 percent prediction interval have been labeled as outliers, i.e. advanced or delayed brain development. On right is: The average gray matter tissue density maps in different ages for the advanced, delayed and normal subject groups indicate a consistent structural change in gray matter -- with a developmental shift between the three groups.
