    "summary": "This systematic review examines human studies on RF electromagnetic exposure with attention to cognitive performance, well-being, physiological parameters, and EEG. It reports that most results (largely from 2G/3G/4G-era signals and other RF sources) indicated no changes in cognition, physiology, or overall well-being, while EEG alpha activity was reported to vary in relation to cognitive functions. The authors emphasize that direct evidence on 5G base station exposures (700 MHz to 30 GHz) for these outcomes in adults is currently lacking and call for targeted research.",
    "key_points": [
        "The review addresses public concern about potential health impacts from increased numbers of 5G base stations.",
        "Most reported findings in the reviewed literature indicated no changes in cognitive function, physiological parameters, or overall well-being under studied RF exposures.",
        "EEG alpha wave strength was reported to vary depending on aspects of cognitive function.",
        "The authors state that studies have not yet investigated adult health outcomes from 5G base station signals at 700 MHz, 3.5 GHz, or 28 GHz.",
        "The analysis described focuses on exposure studies using signals from 400 MHz to 1750 MHz (not 5G mmWave).",
        "The paper highlights the need for dedicated studies to assess 5G base station exposure effects on cognition, well-being, physiological markers, and EEG."
