•Using
sophisticated neuroimaging methods (3D “cortical mapping”), longitudinal
studies were performed on three groups of adolescents
•
•Goal: check changes in brain anatomy
•over time (baseline, 2.3 years, 4.6 years)
•
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.
