Human Brain Development in Health Study

This ongoing study within the Section on Developmental Neurogenomics aims to understand how brain structure and function change over the course of healthy human brain development. It is a continuation of one of the largest and longest-running neuroimaging studies of human brain development in history, which was first-started in the 1990’s by Dr. Judith Rapoport (Chief of the NIMH Child Psychiatry Branch), and subsequently led by Dr. Jay Giedd (now Professor of Child and Adolescent Psychiatry, UCSD). Over 700 volunteers have now become part of this unique effort to map the human brain, and together contributed over 2000 structural magnetic resonance imaging brain scans spanning ages 3 and 30 years.

Recent analyses within this study have addressed the following themes:

  1. Generating fine-scale maps of regional cortical and subcortical development across adolescence
  2. Understanding how regional brain organization varies as a function of differences in overall brain size
  3. Developing new approaches for combining information from in vivo neuroimaging with complimentary maps from postmortem studies if brain histology and gene expression.

We are now expanding the study in two important ways. First, we are re-contacting people who were initially enrolled in the study in childhood or adolescence, and inviting them to return for a follow-up visit in adulthood. Second, we have started an updated “next-generation” phase of the study that is recruiting a new longitudinal cohort of children and adolescents.
