Study: Watching TikTok videos deactivates key cognitive brain regions

Scientific study reveals TikTok videos deactivate key cognitive brain regions

A brain-scan study of 56 young adults found that watching short videos they liked deactivated the dorsal anterior cingulate cortex and dorsolateral prefrontal cortex, regions involved in cognitive control. The deactivation was specific to these regions, as the visual cortex remained active. The researchers caution that this does not indicate impaired cognitive function, but rather an adaptive shift to low-effort processing.
