Effects of parental socioeconomic status on offspring’s fetal neurodevelopment
Bibliographic record
Abstract
Emerging evidence underscores the prenatal period's critical role in shaping later cognition and health, influenced by an intricate interplay of parental genetic and environmental factors. Birth weight is commonly used as a retrospective indicator of fetal development, but recent focus has shifted to more specific proxies of neurodevelopment, like cortical sulcal patterns, which are established in utero and remain stable after birth. This study aimed to elucidate the interrelated effects of parental socioeconomic status, brain volume, birth weight, and sulcal patterns in the anterior cingulate cortex. Utilizing structural Magnetic Resonance Imaging (MRI), parental educational attainment, and related polygenic risk scores, the study analyzed 203 healthy right-handed participants aged 9 to 18. Structural equation modeling demonstrated that the anterior cingulate cortex sulcal pattern is influenced by parental socioeconomic status and global brain volume, with socioeconomic status correlating with a polygenic risk score. These findings suggest that prenatal neurodevelopmental processes may mediate the intergenerational transmission of inequalities.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
