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 ]
At birth the infantile brain contains 100 billion neurons – as many as in the brain of an adult. [4] In order to have this many neurons at birth, the fetus's brain must produce neurons at the rate of 250,000 per minute. [3] At birth, every cortical neuron is connected with about 2500 neurons; after a year, with about 15 000. [5]
Bmp-7 can be detected in the ventricular zone and is secreted into cerebrospinal fluid (CSF). The CSF is an area to promote neurogenesis and it is believed that the synergy between Bmp-7 and other regulators promote cell division along with homeostasis. [12] Other bone morphogenetic proteins are also known to impact corticogenesis in the mouse ...
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. [38]
The amount of time required to generate all the neurons of the CNS varies widely across mammals, and brain neurogenesis is not always complete by the time of birth. [3] For example, mice undergo cortical neurogenesis from about embryonic day (post-conceptional day) (E)11 to E17, and are born at about E19.5. [ 9 ]

Cognitive development is a field of study in neuroscience and psychology focusing on a child's development in terms of information processing, conceptual resources, perceptual skill, language learning, and other aspects of the developed adult brain and cognitive psychology.
