The mid-year full cohort follow-ups for 6―18 months is also included. There is also limited data (not all subjects) from the 3-year follow-up (no imaging) and 2nd- and 3rd-year mid-year interviews. Data Release 5.0 was originally slated for 2022, but its release has been pushed back. It is estimated to be released in the spring of 2023. [5]
Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices. [8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 14–16 years in the temporal lobes (with the superior temporal cortex being last to mature), peaking at about roughly the same age in both sexes ...
The pruning process is shown in this clip that was constructed from MRI scans of healthy children and teens. The time-lapse animation compresses 15 years of brain development (ages 5-20) into just a few seconds. Red indicates more gray matter, blue less gray matter. The changes in color from yellow/red to blue show the pruning process (source ...
Betty Jo "BJ" Casey [1] is an American cognitive neuroscientist and expert on adolescent brain development and self control. [2] She is the Christina L. Williams Professor of Neuroscience at Barnard College of Columbia University where she directs the Fundamentals of the Adolescent Brain (FAB) Lab [3] and is an Affiliated Professor of the Justice Collaboratory at Yale Law School, Yale University.
The human brain is not finished developing by the time a person reaches puberty, or even finishes it. The frontal lobe of the brain has been known to shape itself well into one's 30s. [49] Neuroscientists often cannot agree precisely on when this developmental period ends or if there is an exact age for the end of brain development. [50]
Microglia-mediated synaptic pruning has also been observed to be upregulated during late adolescence and early adulthood, which could also account for the age of onset for schizophrenia often being reported around this time in development (late teens to early 20s for men, and mid-to-late 20s for women) [20] The drug minocycline, a semisynthetic ...

The most current form of the schedules comes from the Gesell Institute of Child Development and is known as the Gesell Developmental Observation-Revised for ages 2 ½ to 9 years. [2] This assessment uses the principles of the schedules to determine the developmental age & stage of an any given child.
