Pregnancy involves radical hormone surges and biological adaptations. However, the effects of pregnancy on the human brain are virtually unknown. Here we show, using a prospective ('pre'-'post' pregnancy) study involving first-time mothers and fathers and nulliparous control groups, that pregnancy renders substantial changes in brain structure, primarily reductions in gray matter (GM) volume in regions subserving social cognition. The changes were selective for the mothers and highly consistent… 
Brain plasticity in pregnancy and the postpartum period: links to maternal caregiving and mental health
TLDR
The changes in brain structure and function that a woman undergoes during the peripartum period are reviewed, outlining associations between these neural alterations and different aspects of maternal care.
Population-based neuroimaging reveals traces of childbirth in the maternal brain
TLDR
Investigating structural brain characteristics in 12,021 middle-aged women from the UK Biobank demonstrates that parous women showed less evidence of brain aging compared to their nulliparous peers, suggesting that parity may involve neural changes that could influence women’s brain aging later in life.
Postpartal Neural Plasticity of the Maternal Brain: Early Renormalization of Pregnancy-Related Decreases?
TLDR
The results reveal the potential for plasticity in the adult female brain following pregnancy and support the assumption that the volume reductions during pregnancy renormalize at least partly in the early postpartal phase.
"Pregnancy Brain": A Review of Cognitive Changes in Pregnancy and Postpartum.
TLDR
It is concluded that pregnancy does confer deficits in working memory relative to nonpregnant controls and whether these effects may confer an advantage to parous women comparable to that seen in lower mammals.
The expectant brain – being pregnant causes changes in brain morphology in the early postpartum period
TLDR
It is concluded that the widespread morphological changes seen in the brain shortly after childbirth reflect substantial neuroplasticity and the experience of pregnancy alone may not be the underlying cause of the adaptations for mothering and caregiving.
Becoming a mother entails anatomical changes in the ventral striatum of the human brain that facilitate its responsiveness to offspring cues
Postpartum Gray Matter Changes in the Auditory Cortex
TLDR
Significant volume increases within all auditory regions and subregions examined might reflect rapid adaptations of the mother's brain in relation to reliably interpreting her newborn’s cries.
Brain orchestration of pregnancy and maternal behavior in mice
TLDR
Unlike females exhibiting lower levels of maternal care, highly maternal females developed transient hypertrophies in somatosensory, entorhinal and retrosplenial cortices among other regions, suggesting coordinated and transient brain modifications associated with maternal performance occurred during gestation and lactation.
The maternal brain: Region‐specific patterns of brain aging are traceable decades after childbirth
TLDR
It is found that a higher number of previous childbirths were linked to less apparent brain aging in striatal and limbic regions, and the strongest effect was found in the accumbens—a key region in the mesolimbic reward system, which plays an important role in maternal behavior.

The plasticity of human maternal brain: longitudinal changes in brain anatomy during the early postpartum period.
TLDR
The first months of motherhood in humans are accompanied by structural changes in brain regions implicated in maternal motivation and behaviors, and increased gray matter volume in the midbrain including the hypothalamus, substantia nigra, and amygdala was associated with maternal positive perception of her baby.
The Maternal Brain: An Organ with Peripartal Plasticity
TLDR
Different forms of peripartum-associated plasticity including changes in neurogenesis and their possible underlying molecular mechanisms are concentrated on and consequences of malfunction in those systems are discussed.
Why the Maternal Brain?
TLDR
It is clear that the female brain undergoes a significant reorganisation en route to motherhood, the results of which are deep and enduring.

TLDR
Investigations of pregnancy-induced cognitive change in human females may benefit by focusing on areas, such as social cognition, where a cognitive advantage would serve a protective function, and by extending the study duration beyond pregnancy into the postpartum period.
