Results from studies indicate that organizational effects are maximized during sensitive periods of brain development. One critical period is weeks 8-24 of gestation. Another sensitive period shortly after birth may exist with a peak in testosterone in male infants during postnatal months 1-5. [ 14 ]
Steroid hormones have several effects on brain development as well as maintenance of homeostasis throughout adulthood. Estrogen receptors have been found in the hypothalamus, pituitary gland, hippocampus, and frontal cortex, indicating the estrogen plays a role in brain development. Gonadal hormone receptors have also been found in the basal ...
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 formation of neurons and the establishment of basic neural circuits in the developing brain are crucial for laying the foundation of the brain's structure and function, and disruptions during this period can have long-term effects on cognitive and emotional development.
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 ]
Early childhood development is the period of rapid physical, psychological and social growth and change that begins before birth and extends into early childhood. [1] While early childhood is not well defined, one source asserts that the early years begin in utero and last until 3 years of age. [1]
Similar to brain plasticity, it specifically involves how neurons and synapses adapt during development. Most of these connections form from birth to early childhood, following three main processes, with critical periods determining lasting changes. The term can also describe how an embryo or larva adjusts its traits based on the environment.
Neville and the Brain Development Lab were also responsible for creating "Changing Brains", a program of video segments aimed at non-scientists to describe what research has revealed the effects of experience on human brain development. The series aims to inform parents, teachers and policymakers on how to help children develop to their full ...
