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 ]
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 ]
The hieroglyph for brain, occurring eight times in this papyrus, describes the symptoms, diagnosis, and prognosis of two patients, wounded in the head, who had compound fractures of the skull. The assessments of the author (a battlefield surgeon) of the papyrus allude to ancient Egyptians having a vague recognition of the effects of head trauma.
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 ...
The fetus, while not able to make sense of and process what they are hearing, has the ability to hear, feel pressure and different temperatures. The third trimester has many perinatal brain development milestones. In the 30th week, the fetus can control its own body heat. In the 31st week, the fetus is able to process more stimuli and information.
The human brain has evolved around the metabolic, environmental, and social needs that the species has dealt with throughout its existence. As hominid species evolved with increased brain size and processing power, the overall metabolic need increased. Compared to chimpanzees, humans consume more calories from animals than from plants.
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 ...
