The findings show that some parts of the human brain may shrink in size during pregnancy, but become better connected. A few regions of the brain remain untouched by the transition to motherhood ...
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
The scans also showed an increase of about 10% in white matter microstructural integrity, a measure of the health and quality of the connections between brain regions, peaking late in the second ...
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 increase in kidney clearance during pregnancy causes more iodide to be excreted and causes relative iodine deficiency and as a result an increase in thyroid size. Estrogen-stimulated increase in thyroid-binding globulin (TBG) leads to an increase in total thyroxine (T4), but free thyroxine (T4) and triiodothyronine (T3) remain normal. [5]
This diagnosis is generally found in routine fetal anomaly scans at 18–22 weeks gestation. It is one of the more common abnormal brain findings on prenatal ultrasound, occurring in around 1–2 per 1,000 pregnancies. [4] In many cases of mild ventriculomegaly, however, there is resolution of ventriculomegaly during the pregnancy.
Scans of the changes that occur in the brain of a pregnant woman. Researchers followed a 38-year-old woman three weeks before conception, and two years postpartum, tracking the changes to her ...
Different hormone levels in the maternal brain and the overall well being of the mother account for 40%–50% of differences in the mother's attachment to her infant. [12] Mothers experience a decrease in estrogen and an increase in oxytocin and prolactin caused by lactation, pregnancy, parturition and interaction with the infant. [13]
