🧠A neuroimaging study of 222 university students reveals that generative AI use produces divergent brain and mental health outcomes depending on usage patterns: functional AI use correlates with better academics and larger prefrontal regions, while socio-emotional AI use associates with depression, anxiety, and smaller social-processing brain areas. The findings suggest AI's impact on the developing brain is highly context-dependent, requiring differentiated approaches to maximize educational benefits while minimizing mental health risks.
