The previous point is well illustrated by the work of researchers affiliated with the National Institute of Mental Health and UCLA (University of California, Los Angeles).
	Using a sophisticated neuroimaging technique known as 3-dimensional cortical mapping, the investigators performed a series of MRI brain scans in an effort to track changes in anatomy over time.
	Children received brain scans at entry into the study (baseline), and again at repeated intervals of approximately 2 and 5 years.
