Abstract

fetched live from OpenAlex

Background: Many studies suggest that urban upbringing might increase the risk of developing schizophrenia (SCZ). However, the precise brain changes associated with urban upbringing remain poorly understood. In this study, we investigated how urban upbringing might influence cortical gyrification, a brain feature that reflects early structural development. Methods: The study included 70 Healthy Controls (HC) and 87 individuals diagnosed with SCZ, all aged between 18 and 50 years. Participants and their caregivers were interviewed to collect information about birthplace and upbringing location. Based on data from the Indian Census (1971-2011), upbringing locations were categorized into three groups: rural, town, and city. An urbanicity index was calculated using a previously established method. Brain anatomical MRI images were processed using FreeSurfer. Regression analysis was conducted using the QDEC interface, with the gyrification index (GI) as the dependent variable, and urbanicity index, sex, and age as predictors. Results: = .001). Additionally, a significant interaction effect between the diagnosis and urbanicity index was found in multiple brain regions. Conclusions: These findings suggest that urban living has a significant influence on brain development. Identifying such risk factors and underlying mechanisms could help develop prevention strategies and guide improvements in urban planning.

Teacher imitation

Not 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.
