The findings show that some parts of the human brain may shrink in size during pregnancy, but become better connected.
With the brain, this process happens early in development, again during puberty, and pregnancy probably reflects another wave of cortical refinement.” Increase in brain white matter during pregnancy
Researchers have created one of the most detailed maps of how pregnancy changes the brain, according to a new study. Pregnancy changes the brain more than previously known, study finds Skip to ...
Structural changes continue during adulthood as brain shrinkage commences after the age of 35, at a rate of 0.2% per year. [4] The rate of decline is accelerated when individuals reach 70 years old. [5] By the age of 90, the human brain will have experienced a 15% loss of its initial peak weight. [6]
Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from 1–12 months after surgery, or longer. [1] In some cases, this disorder may persist for several years after major surgery. [2] POCD is distinct from emergence delirium. Its causes are under ...
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 brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. [6] The brain matter can be broadly classified as either grey matter, or white matter.
Researchers said on Monday they have for the first time mapped the changes that unfold as a woman's brain reorganizes in response to pregnancy, based on scans carried out 26 times starting three ...
