Scientists found that this led to a long-term decrease in the volume of gray matter in the woman’s brain and a temporary increase in the volume of white matter, the press service of the University of California, Santa Barbara reported.
“For the first time, we were able to observe changes in the structure of a pregnant woman’s brain during childbirth,” said Emily Jacobs, a professor at the University of California, San Francisco. “The fact that these changes exist, and their dimensions, suggests that the adult female brain can maintain a high level of plasticity for a long time, and that the nervous system can change its functions, potentially helping the female brain adapt to raising children.”
Experts obtained similar information while monitoring the health and brain function of a 38-year-old California woman who had a child conceived through IVF. The researchers studied the structure of her brain three weeks before conception using an MRI scanner, and conducted 20 similar studies at different stages of pregnancy, as well as in the first two years after the child was born.
Subsequent comparison of these images indicated that the onset of a woman’s first pregnancy in her life is accompanied by many changes in the structure of the entire brain in general, and in the structure of white and gray matter in particular. For example, the researchers found that pregnancy led to a small (2-5%) but significant decrease in the volume of gray matter, which was in some areas of the hippocampus (6-8%), as well as the caudate nucleus and some cortical areas associated with attention and emotions.
The researchers noted that these changes in gray matter structure gradually increased as the fetus developed and did not disappear even after pregnancy. In contrast, the volume of white matter in the California woman’s brain increased significantly during the first and second trimesters of pregnancy, but after the baby was born, this indicator returned to baseline values by the time of the first MRI session.
Experts hope that further study of these changes in the structure of white and gray matter will help them understand how the various hormones produced during pregnancy activate the “motherhood program” in a woman’s brain and change its structure. Understanding this will make it possible to understand the processes that lead to changes in women’s behavior when they have children, as well as why some women develop postpartum depression.

The Amazing Transformation of a Pregnant Woman’s Brain: What Happens During Pregnancy and Beyond
Pregnancy is a complex and multifaceted journey that affects a woman’s body in numerous ways. While the physical symptoms of pregnancy, such as morning sickness and fatigue, are well-documented, recent research has shed light on the remarkable changes that occur in a pregnant woman’s brain. In this article, we’ll delve into the fascinating transformations that take place during pregnancy and explore what they mean for new mothers.
Changes in Brain Structure
A groundbreaking study by the University of California, Santa Barbara, found that pregnancy leads to a long-term decrease in the volume of gray matter in the brain, accompanied by a temporary increase in white matter volume [[1]]. Gray matter is responsible for processing information and controlling various functions, such as emotions, attention, and memory, while white matter facilitates communication between different brain regions.
The researchers observed these changes in a 38-year-old California woman who conceived through IVF. They conducted 20 MRI scans at different stages of pregnancy and in the first two years after childbirth, providing an unprecedented glimpse into the brain’s transformation during this period.
The Impact of Pregnancy on Brain Function
The study revealed that the onset of a woman’s first pregnancy is accompanied by significant changes in brain structure, particularly in the hippocampus, caudate nucleus, and cortical areas associated with attention and emotions [[2]]. These changes are not limited to the pregnancy period, as the researchers found that the decrease in gray matter volume persisted even after childbirth.
On the other hand, the volume of white matter increased significantly during the first and second trimesters of pregnancy but returned to its original state after childbirth. This temporary increase in white matter volume may be linked to the brain’s ability to adapt to the demands of motherhood.
The Brain’s Plasticity
The findings suggest that the adult female brain is capable of remarkable plasticity, allowing it to reorganize and adapt to the challenges of pregnancy and motherhood [[3]]. This flexibility is essential for a woman’s brain to adapt to the new responsibilities and demands of caring for a child.
Practical Implications for Pregnant Women
While the study’s results are fascinating, they also have practical implications for pregnant women. Understanding the changes that occur in the brain during pregnancy can help women better prepare for the challenges of motherhood and develop strategies to support their brain health.
Some tips for pregnant women include:
Prioritizing self-care and stress management to support brain health
Engaging in cognitive exercises and activities that promote brain plasticity
* Building a support network to help with the emotional and physical demands of motherhood
Conclusion
Pregnancy is a complex and multifaceted journey that affects a woman’s brain in profound ways. The remarkable changes that occur in brain structure and function during this period are a testament to the brain’s incredible plasticity and ability to adapt to new challenges.
By understanding these changes, pregnant women can better prepare themselves for the demands of motherhood and take steps to support their brain health. As researchers continue to uncover the secrets of the pregnant brain, we may uncover even more insights into the incredible journey of motherhood.
