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 ...
Brain areas that undergo significant post-natal development, such as those involved in memory and emotion are more vulnerable to effects of early life stress. [ 58 ] [ 64 ] For example, the hippocampus continues to develop after birth and is a structure that is affected by childhood maltreatment. [ 64 ]
Preoperational Stage (24 Months to 7 Years) Concrete Operational Stage (7 Years to 12 Years) Formal Operational Stage (12 Years and Up) Infant cognitive development occurs in the Sensorimotor stage which starts at birth and extends until the infant is about 2 years of age. The sensorimotor stage is made up of six sub-stages.
On average, this fragmented period wanes off at around 4.7 years. [1] [2] Around 5–6 years of age in particular is thought to be when autobiographical memory seems to stabilize and be on par with adults. [3] [4] The development of a cognitive self is also thought by some to have an effect on encoding and storing early memories. [5]
ROCKFORD, Ill. (WTVO) – The American Academy of Pediatrics has updated its literacy promotion policy for the first time in 10 years. The update is based on research that shows that it’s never ...
Brain mapping can show how an animal's brain changes throughout its lifetime. As of 2021, scientists mapped and compared the whole brains of eight C. elegans worms across their development on the neuronal level [68] [69] and the complete wiring of a single mammalian muscle from birth to adulthood.

As we age, our brain experiences both structural and functional changes. Over time, this can cause a decline in cognitive abilities, memory, and even emotional regulation.
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.
