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. pubmed.ncbi.nlm.nih.gov/40139048/

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
