[+0] Brain structure variations of 15-20% exist across normal populations without corresponding functional impairments or harm. [i]
[+0] Correlation between social media use and brain structure does not establish causation given confounding variables like socioeconomic status. [i]
[+0] Adolescents with pre-existing anxiety disorders use social media 40% more frequently, potentially explaining observed neural differences. [i]
[+0] Normal adolescent synaptic pruning reduces gray matter volume by 10-20% without pathology according to established developmental trajectories. [i]
[+0] Cortical thinning of 0.5mm annually throughout adolescence reflects increased neural efficiency rather than damage. [i]
[+0] The Giedd longitudinal neuroimaging study documented 15% prefrontal gray matter decline in healthy adolescents between ages 12-18. [i]
