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 study collects data on the behavior and brain development of over 11,500 children beginning at age 9-10 and continuing through young adulthood. [2] The study collected data from youth in seven primary domains: physical health, mental health, brain imaging, biospecimens, neurocognition, substance use, and culture and environment.
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 ...
Identity development is a stage in the adolescent life cycle. [96] For most, the search for identity begins in the adolescent years. During these years, adolescents are more open to 'trying on' different behaviours and appearances to discover who they are. [97]
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
Total cerebral and gray matter volumes peak during the ages from 10–20 years (earlier in girls than boys), whereas white matter and ventricular volumes increase. There is a general pattern in neural development of childhood peaks followed by adolescent declines (e.g. synaptic pruning). Consistent with adult findings, average cerebral volume ...

Developmental neuropsychology combines the fields of neuroscience and developmental psychology, while drawing from various other related disciplines.It examines the relationship of behavior and brain function throughout the course of an individual's lifespan, though often emphasis is put on childhood and adolescence when the majority of brain development occurs.
