The functional implications these brain changes may have for birthing parents have yet to be determined, said Dr. Elseline Hoekzema, head of the Pregnancy and the Brain Lab at Amsterdam University ...
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 said the findings, based on brain scans from one mother, may represent one of the first comprehensive maps of changes in the organ before, during and after human pregnancy.
Choline before pregnancy is also related to changes in the birth, death, and migration of cells in the hippocampus during the development of the baby rats in the womb. Choline is also associated with the different location and shape of neurons involved in memory storage within the brain.
Parental experience, as well as changing hormone levels during pregnancy and postpartum, cause changes in the parental brain. [1] Displaying maternal sensitivity towards infant cues, processing those cues and being motivated to engage socially with her infant and attend to the infant's needs in any context could be described as mothering ...
These changes may contribute to maternal behaviour during pregnancy and for a year after birth. They could also impact maternal-foetal bonding and the mother’s response to her baby’s cues.
