Development of the social perception pathway across the third trimester of gestation and perinatal transition

Published on 2026-10-15 by @MIT

Abstract: AbstractBabies display social perceptual skills within hours of birth which may indicate that the neural predecessors of such skills have prenatal origins. However, the putative fetal neural infrastructure supporting these skills remains unexplored. Data from 497 participants scanned between 28–44 weeks postmenstrual age were examined to map the development of intrinsic functional connectivity (iFC) within the proto social pathway (pSP), encompassing the superior temporal sulcus (STS), a regio[...]


Our summary: The study maps the development of intrinsic functional connectivity within the proto social pathway and proto ventral pathway during the third trimester. Significant increases in connectivity were observed, indicating early neural architecture for social perception. Findings suggest that key features of the social brain begin to develop prenatally, laying the groundwork for later social skills.
