Researchers observed growth in hypothalamus and substantia nigra, parts of the brain responsible for emotion and reward behavior. Baby's cry triggers oxytocin, which is a happy hormone. Maternal feelings such as protectiveness and overwhelming love are aggravated. There is also proof that there is a change in perception of smell and sound in moms to help communicate with their babies.
Giving birth to a newborn and experiencing motherhood is something only a woman can feel. Research has shown that there is an increase in the size of the mid brain of a woman after child birth. Though brain size, especially the gray matter volume does not increase easily in a short period.
However, the adult gray matter volume changes rapidly when the brain experiences exceptional learning, injury, infection, or a major environmental change, as reported in Behavioral Neuroscience in October of 2010. The changes seem to begin, the moment the baby is born.
Physiological And Emotional Changes
Growth Of Certain Regions Of Brain
Researchers have specifically observed growth in new mothers’ brain areas such as, hypothalamus, substantia nigra and amygdala, parietal lobe and prefrontal cortex. These regions are responsible for a person’s emotion, reasoning and judgement, the pleasure and reward behavior.
Release Of Dopamine
Scientists have found in several studies that just by staring at her baby, the reward centers of a mother’s brain light up. This creates dopamine, a chemical messenger that interacts with certain brain cells and causes a mother to feel really good.1
Increase In The Level Of Oxytocin
As a mother hears her baby’s pleasant coos and cries, there is an increase in the level of oxytocin in the woman’s body.
New Neural Pathways
The simple act of caring for her baby, creates new neural pathways in the mother’s brain.
The maternal feelings of overwhelming love, fierce protectiveness, and constant worry, begin with reactions in the brain.
Development Of Mothering Skills
According to the researchers, the changes to the brain of the mother may be linked to the development of mothering skills after childbirth. Hence the period directly after childbirth is an important time for new moms.
Levels Of Enthusiasm
According to studies, it has also been shown that compared to the less-enthusiastic moms, the more enthusiastic moms were more likely to develop bigger mid-brain. There is also a growth in the key regions linked to maternal motivation, rewards, and the regulation of emotions.
Smells, Sounds And Communication
The experts from Hebrew University in Jerusalem, found that changes in the brain, particularly associated with the perception of smells and sounds, help mothers to communicate with their babies.
Thus, motherhood does have a huge impact on a woman’s brain. Women are basically happier and possibly smarter being a mom. Many scientists believe that mapping the maternal brain may be a key to understanding why so many new mothers experience serious anxiety and depression. This may also help develop new therapeutic approaches to treat the conditions like postpartum depression and compulsive disorders.

ha ha. When my son turned 18, he asked me, with a silly grin, "So, mom, I'm 18 ... are you sane now?" Got to love a good sense of humor but I'd have traded those 4 years for some sanity, for sure.
Yes exactly! We have 2 teen daughters and well lets just say I like vodka :-) and it goes down st8 up lol
All hell breaks loose. You never sleep again. You worry the rest of your life. Even tho they bring joy the worry is always there.
Her entire body n mind revolves around her baby now a days all the working woman worry who will take care of tiny tot they depend on their mother automatically n feel oh my baby is safe in my mother s hands
There was another study done that proved that the mothers of boys were found to ha e their som's dna in their brain. It might have been an article on the Huffpost.
when a woman turns mother, her brains become active and starts working exactly opposite of logic and her husband gets tortures all the time on all the issues at all the places.
It goes into overdrive mode and never slows down until they are adults. Then it idles in neutral between visits......:)
