The term “mom brain” is often used to describe forgetfulness or absent-mindedness in mothers, typically attributed to sleep deprivation and exhaustion. However, there’s more happening beneath the surface. Let’s explore the fascinating neurological changes that occur in a mother’s brain during and after pregnancy.
Many mothers describe having a child as one of the most significant experiences of their lives. Scientifically, this is true, as motherhood brings about profound changes in the brain’s structure. Research published in the Journal of Behavioral Neuroscience reveals that mothers experience increased gray matter in specific brain regions, such as the parietal lobes and prefrontal cortex, shortly after giving birth. This growth continues over the first few months of motherhood.
Additionally, areas like the amygdala and hypothalamus, which are crucial for emotional regulation, survival instincts, and hormone production, also show growth. These changes help mothers maintain a positive outlook towards their babies and manage the demands of caring for a newborn, even during sleepless nights.
A study conducted by researchers at the University of Toronto Mississauga examined the brain activity of 22 mothers to understand the amygdala’s role in maternal bonding. The study found that mothers generally exhibited stronger responses to their own babies compared to others. This heightened sensitivity in the amygdala is linked to positive maternal experiences, including satisfaction with motherhood and a good mood.
Conversely, mothers with reduced amygdala responses reported higher stress and anxiety levels, indicating a more challenging maternal experience. These findings underscore the importance of activating brain regions that buffer against negative emotions in new mothers.
Oxytocin, often called the “love hormone,” plays a crucial role in bonding and affection. It is released during childbirth and breastfeeding, facilitating the bond between mother and child. During pregnancy, oxytocin levels spike, and areas with high oxytocin receptor density, like the amygdala, are particularly active when mothers interact with their babies.
In a study published in Frontiers in Psychology, researchers found that mothers exhibited more intense brain activity in the dopamine reward system when exposed to the scent of newborns compared to women without children. This system is involved in reward learning and motivates mothers to nurture and care for their babies.
The neurological changes that occur in mothers help explain the deep attachment they feel towards their children. This bond persists even as children grow older, highlighting the powerful connection forged through these brain transformations.
Understanding these changes not only sheds light on the concept of “mom brain” but also emphasizes the incredible adaptability and resilience of the maternal brain. As we continue to explore these neurological processes, we gain a deeper appreciation for the complex and rewarding journey of motherhood.
Explore an interactive brain map to identify and learn about the specific brain regions that undergo changes during motherhood. Focus on areas like the parietal lobes, prefrontal cortex, amygdala, and hypothalamus. Reflect on how these changes might influence behavior and emotional responses.
Analyze a case study of a new mother, focusing on her experiences and challenges. Discuss how the neurological changes described in the article might explain her behaviors and emotions. Present your findings in a group discussion.
Participate in a simulation that demonstrates the effects of oxytocin on bonding and affection. Observe how increased levels of this hormone influence interactions and emotional responses. Share your observations and relate them to the article’s findings.
Engage in a role-playing exercise where you simulate the experience of a mother with varying levels of amygdala activation. Discuss how these differences might affect maternal bonding and stress levels. Reflect on the importance of emotional regulation in motherhood.
Develop a research proposal to further investigate one of the neurological changes discussed in the article. Consider potential methodologies, expected outcomes, and the significance of your research. Present your proposal to the class for feedback.

You’ve probably heard the term “mom brain.” People use this term to describe when things slip a mother’s mind. It turns out, this is likely just the result of sleep deprivation and exhaustion. So, what is actually happening inside a mother’s brain?
Hi, everyone! Lissette here for Dnews. Many mothers report that having a child is one of the most meaningful events they’ve ever experienced. It’s life-changing. From a scientific perspective, they’re right—this even extends to the structure of their brains.
Mothers experience neurological changes that begin during pregnancy and continue throughout early motherhood. In a study published in the Journal of Behavioral Neuroscience, researchers examined mothers’ brains at 2-4 weeks after giving birth and then again around 3 months later. Using MRI technology, they found that mothers had increased gray matter in certain areas, including the parietal lobes and prefrontal cortex. Yes, their brains literally grew.
Additionally, some of the growth occurred in areas like the amygdala and hypothalamus, which are associated with emotional regulation, survival instincts, and hormone production. These changes appear to be linked to mothers having a positive view of their babies and an increase in positive feelings towards them. This is what helps moms respond to a crying baby multiple times at night without losing their affection.
In a study, researchers at the University of Toronto Mississauga analyzed the brain activity of 22 mothers to see if there was anything special happening in their amygdala when they looked at their babies versus the babies of strangers. It was expected that mothers would respond more strongly to their own babies. Some women did report higher feelings of satisfaction with motherhood, a more positive mood, and generally good experiences. Conversely, when the amygdala did not show increased sensitivity during motherhood, it negatively affected the bond between mother and child. Women who had reduced amygdala responses to photos of their babies reported poorer quality of maternal experience, including increased levels of stress and anxiety. Essentially, these mothers felt they were having a hard time.
We know from other studies how important activating these brain regions can be in buffering against negative emotions in new mothers. In fact, postpartum depression is associated with the binding sensitivity of receptors in the brain that affect the amygdala and other structures involved in the dopamine reward system. This is the same system activated when we fall in love. Studies have shown that the same neurological processes are involved in falling in love romantically as well as in bonding with your baby.
One hormone involved in this process is oxytocin, often referred to as the love hormone for its role in bonding and affection. Your body releases it when you hug someone or cuddle, creating that comforting feeling. It is also released during childbirth, is associated with breastfeeding, and facilitates bonding with a newborn. The hormone spikes during pregnancy, and regions with a high density of oxytocin receptors, like the amygdala, are specifically activated in mothers’ brains when responding to their babies’ faces and scents.
In one study published in the journal Frontiers in Psychology, researchers gave women baby pajamas that had been worn by two-day-old newborns. One group consisted of mothers who had just given birth, while the other group included women who had never had children. When asked to sniff the pajamas, all women could detect the “baby scent” to the same degree. However, what was happening in their brains was different. Mothers exhibited more intense brain activity in the dopamine reward system compared to women who had never had children. This system is involved in reward learning and motivates us to act in ways that bring us closer to the reward—in mothers’ cases, their baby.
So yes, mothers can be quite attached to their babies. It’s why they can’t stop with the affection—even when their children are grown. So how about showing your mom some love in return—with something special from Kay Jewelers? Because every gesture of love begins with Kay.
