The effect of high frequency radio waves on human brain activity: an EEG study
Bibliographic record
Abstract
Electromagnetic fields (EMF) produced by electronic devices have long raised public concern. Although no studies have shown brain injury due to the use of these devices, some individuals report developing headaches or localized warming during cell phone use. The aim of this study was to determine the effect of radio frequency EMF on human electroencephalography (EEG) signals. A single blind randomized test procedure was used in this study. Ten healthy subjects were exposed to EMF from a cordless phone and wireless router, which emit at 900MHz and 2400MHz, respectively. Three 100 second trials for each condition were conducted on each subject. The subject’s EEG was also measured while wearing a Farabloc® hood which blocks any EMF with frequencies above 1000 Hz. Neither the cordless phone nor the wireless router produced any significant changes in the EEG of the subjects compared to the control condition. Our results imply that the everyday utilized wireless communication devices such as wireless phones and routers have little influence on the electrical activity of the brain in the short term.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
