Claim ID
connectivity-results
Assertion
EEG connectivity was strongest in the brain-only group, intermediate in the search engine group, and weakest in the LLM group, which showed up to 55% lower total connectivity (dDTF magnitude) than the brain-only group in some frequency bands.
Quote
EEG revealed significant differences in brain connectivity: Brain-only participants exhibited the strongest, most distributed networks; Search Engine users showed moderate engagement; and LLM users displayed the weakest connectivity. [...] The LLM group showed the least extensive connectivity, with up to 55% reduced total dDTF magnitude compared to the Brain-Only group in low-frequency semantic and monitoring networks.
