Comment; Prefrontal, frontal & frontotemporal excitability have been ASSOCIATED with use of cell phones. It’s also important to keep in mind that we don’t have a “pure” lab experiment. How can we tease out the effect of cell phones from smart meters, routers, blue-tooth and the many other EMF generating devices? Add to this the fact that cell phones continue to evolve, from analog, to digital, 1st, 2nd, 3rd generation all have different frequency transmissions and different power levels, fold in the unknown effects of other transmission bands, the evolving use of 5G protocols. This is a very complex problem. So far we have identified problems that can be linked with sleep disturbances, ADD/ADHD, impulsivity. Another area to keep in mind is addiction; a disease of “more” (of whatever substance, activity etc.). Food, Sex, Sex & love, Gambling, Video gaming, etc. all are recognized behavioral addictive disorders. Adolescents in particular often appear to exhibit addictive behavior with their digital devices. The pre-frontal cortex governs impulsivity, it doesn’t fully develop until the mid-20’s. It may take time, generations, before the full extent of potential damage is appreciated.

Due to its attributes, characteristics, and technological resources, the mobile phone (MP) has
become one of the most commonly used communication devices. Historically, ample evidence has ruled out the substantial short-term impact of radiofrequency electromagnetic field (RF-EMF) emitted by MP on human cognitive performance. However, more recent evidence suggests potential harmful effects associated with MP EMF exposure. The aim of this review is to readdress the question of whether the effect of MP EMF exposure on brain function should be reopened. We strengthen our argument focusing on recent neuroimaging and electroencephalography studies, in order to present a more specific analysis of effects of MP EMF exposure on neurocognitive function. Several studies indicate an increase in cortical excitability and/or efficiency with EMF exposure, which appears to be more prominent in fronto-temporal regions and has been associated with faster reaction time. Cortical excitability might also underpin disruption to sleep. However, several inconsistent findings exist, and conclusions regarding adverse effects of EMF exposure are currently limited. It also should be noted that the crucial scientific question of the effect of longer- term MP EMF exposure on brain function remains unanswered and essentially unaddressed.
