The plasticity of human maternal brain: Longitudinal changes in brain anatomy during the early postpartum period

Open access

Abstract

Animal studies suggest that structural changes occur in the maternal brain during the early postpartum period in regions such as the hypothalamus, amygdala, parietal lobe, and prefrontal cortex and such changes are related to the expression of maternal behaviors. In an attempt to explore this in humans, we conducted a prospective longitudinal study to examine gray matter changes using voxel-based morphometry on high resolution magnetic resonance images of mothers' brains at two time points: 2-4 weeks postpartum and 3-4 months postpartum. Comparing gray matter volumes across these two time points, we found increases in gray matter volume of the prefrontal cortex, parietal lobes, and midbrain areas. Increased gray matter volume in the midbrain including the hypothalamus, substantia nigra, and amygdala was associated with maternal positive perception of her baby. These results suggest that the first months of motherhood in humans are accompanied by structural changes in brain regions implicated in maternal motivation and behaviors.

TL;DR

In a prospective longitudinal MRI study of 19 mothers, gray matter volume increased from 2–4 weeks to 3–4 months postpartum in prefrontal, parietal, and midbrain regions. Mothers’ positive perception of their baby at Time 1 predicted gray matter increase in a midbrain cluster including hypothalamus, amygdala, and substantia nigra.

Key findings

  • From Time 1 (2–4 weeks postpartum) to Time 2 (3–4 months postpartum), mothers showed increased gray matter volume in superior, middle, and inferior prefrontal cortex, precentral and postcentral gyrus, superior and inferior parietal lobe, insula, and thalamus, p < .05 FDR corrected, >100 voxels; no region showed decreased gray matter volume.
  • Positive thoughts on baby at Time 1 averaged 6.11 (SD = 2.83; range 1–12) and significantly predicted gray matter volume change in a midbrain cluster including hypothalamus, amygdala, and substantia nigra, controlling for parenting experience and scan interval, β = .44, p = .01.
  • Positive thoughts on parenting averaged 8.21 (SD = 7.71; range 1–32) and did not significantly predict gray matter changes in the same midbrain region.

Methods

  • Prospective longitudinal study of 19 biological mothers of full-term, healthy infants (mean age = 33.27, SD = 6.07), recruited at Yale-New Haven Hospital; all were right-handed, Caucasian, married or cohabiting, and breastfeeding.
  • High-resolution T1-weighted MRI scans were obtained at 2–4 weeks postpartum (Time 1) and 3–4 months postpartum (Time 2), with an average interval of 76.53 days (SD = 9.88).
  • Optimized voxel-based morphometry (VBM) with paired t tests tested gray matter changes; whole-brain significance used FDR 5% and extent threshold of 100 voxels. Multiple regression tested associations between YIPTA-R positive thoughts on parenting/baby and midbrain gray matter volume changes, controlling for parenting experience and scan interval.

Limitations

  • The paper states the sample is relatively small and requires replication in larger groups; causal directionality is not clear; maternal behaviors were measured by subjective reports; and VBM has limited ability to interpret microstructural/functional nature of findings.
  • The paper notes the sample included healthy mothers of healthy infants in supportive environments, so mothers with genetic/environmental risk factors may show different patterns.
  • The paper states other factors should be monitored in future studies, including hormones, pregnancy stress, menstrual cycle changes, hydration, weight, and nutritional status; it also suggests future studies include pregnancy baseline scans and comparisons with age-matched women without parenting experience.

  • The paper relies on this without support.

    The hypothesis that similar structural changes occur in the brain of human mothers during the early postpartum period has not been rigorously tested in human mothers yet.

    “However, this hypothesis has not been rigorously tested in human mothers yet.”
  • The paper relies on this without support.

    The sample of healthy mothers of healthy infants living in supportive environments is representative of normative human mothers.

    “our findings on the plasticity of the parental brain demonstrate normative changes among human mothers since the sample included healthy mothers of healthy infants who lived in supportive environments.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
