Acute exposure to a 902 MHz GSM mobile phone field did not significantly change mismatch negativity amplitude or latency in healthy young adults.

Plain English Summary

Summary written for general audiences

Researchers recorded mismatch negativity responses to duration, intensity, frequency, and gap changes in 17 healthy young adults while a GSM phone was placed on either ear with the field on or off. The mismatch negativity was elicited by all deviant types, but its amplitude and latency showed no significant differences due to EMF exposure for any deviant type. The authors concluded there was no conclusive evidence that acute GSM mobile phone EMF exposure affects cortical auditory change detection processing reflected by the mismatch negativity.
