Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Individuals living in urban environments show higher brain activity in stress-related regions, and reduced grey matter volume in dorsolateral prefrontal cortex and pregenual anterior cingulate cortex is associated with urban exposure during the first 15 years of life. → Falkenstein Kim 2026
Evidence¶
Falkenstein Kim 2026¶
Falkenstein Kim, Pauley Claire, Kühn Simone. (2026). Investigating effects of day-to-day variations in environmental exposure on the human brain: study protocol for the Day2Day Environment project. BMC Neuroscience. https://doi.org/10.1186/s12868-026-01052-z
q2 · i? · the article prints no effect size for this finding · design · r1
The protocol summarizes prior long-term living-environment studies, stating "individuals living in urban environments show higher brain activity in stress-related brain regions" and reduced grey matter volume tied to urban exposure during upbringing. No effect sizes are printed.
"individuals living in urban environments show higher brain activity in stress-related brain regions [8, 9], and structural deficits, namely reduced grey matter volume in the dorsolateral prefrontal cortex and pregenual anterior cingulate cortex associated with urban exposure during the first 15 years of life"
