*A new study published in Developmental Science suggests prenatal brain growth may influence early childhood language development, PsyPost reports. Researchers focused on whether prenatal brain development in language-related regions could help predict how many words children produce in toddlerhood.
Two areas of the brain sit at the center of the research. One is the superior temporal gyrus in the temporal lobe. It plays a central role in processing sound and supporting language comprehension. The other is the inferior frontal gyrus which helps drive speech production. It also supports cognitive control and regulates how the brain manages and inhibits responses during communication.
Both regions start forming around 24 to 25 weeks of pregnancy and continue developing through the third trimester. Scientists have long linked these areas to language ability after birth. They know far less about how prenatal structure affects later speech outcomes.
Annika Werwach of the Max Planck Institute for Human Development led the research. Her team analyzed fetal brain scans from the Cambridge Human Imaging and Longitudinal Development project. The sample included 41 fetuses scanned between 30 and 33 weeks of gestation.

Early results showed no clear connection between prenatal brain measurements and vocabulary at 18 months. A different pattern emerged later in development.
Children with larger prenatal measurements in the superior temporal gyrus produced more words between ages two and three. The effect appeared across both hemispheres, consistent with evidence that young children rely on both sides of the brain during early language learning.
In contrast, the inferior frontal gyrus did not show a meaningful link to early vocabulary growth.
Researchers concluded that early brain development and later language ability appear more connected than previously understood, suggesting continuity between prenatal brain organization and later language networks.
The study also notes several limitations. The final sample included about two dozen children. The participants came from predominantly white, middle-class families. The research focused only on expressive vocabulary and did not measure comprehension or broader language skills.
