Sources and components of fine air pollution exposure and brain morphology in preadolescents Air pollution is an emerging novel neurotoxicant during childhood and adolescence. However, little is known regarding how fine particulate matter (PM2…

We’re now learning that air pollution sneaks in to shape developing brain in children and adolescents. Our latest @hertinglab.bsky.social study looked at brain MRIs from 10,095 children and found that exposure to specific sources of PM2.5 is related to differences in gray matter morphology… (1/2)

The @hertinglab.bsky.social is on a roll, friends. New from Nate Overholtzer: age, sex, and BMI differences in amygdala and its subregions.

A systematic review of air pollution exposure and brain structure and function during development Air pollutants are known neurotoxicants. In this updated systematic review, we evaluate new evidence since our 2019 systematic review on the effect of…

New review from Jess Morrel & the @hertinglab.bsky.social exploring links between air pollution and the developing brain.

tl;dr: this literature is growing, but there are still gaps in time (sensitive exposure windows, timing of exposure -> brain changes) and space (most data from US/Europe)

New paper alert! The amygdala is key to emotional, social & appetitive behavior— but how do its subregions develop in preadolescence? In ~4,000 youth, we found:
🧠 Age → near-global amygdala expansion
🧬 Sex differences in apportionment
⚖️ Higher BMIz → smaller basolateral subregions
