Plain English Summary
Researchers exposed 18 people to LTE (4G cellular) radiation for 30 minutes near their right ear, then used brain scans to measure changes in spontaneous brain activity. They found decreased activity in multiple brain regions, including areas responsible for hearing, movement control, and decision-making. This suggests that even brief exposure to modern wireless signals can alter how the brain functions at rest.
Why This Matters
This study adds to mounting evidence that radiofrequency radiation from modern wireless technologies directly affects brain function. What makes this research particularly relevant is its focus on LTE signals, the backbone of 4G networks that power most smartphones today. The researchers used sophisticated brain imaging to detect changes in spontaneous neural oscillations after just 30 minutes of exposure. The affected brain regions include areas critical for auditory processing, motor control, and executive function. While the study doesn't specify exact power levels, the exposure setup mimicked real-world phone use with the radiation source positioned near the ear. The science demonstrates that our brains respond measurably to the electromagnetic fields generated by everyday wireless devices, contradicting claims that these signals are biologically inert.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 30 minutes
Study Details
The motivation of this study is to evaluate the possible alteration of regional resting state brain activity induced by the acute radiofrequency electromagnetic field (RF-EMF) exposure (30min) of Long Term Evolution (LTE) signal.
We designed a controllable near-field LTE RF-EMF exposure environment. Eighteen subjects participate...
We found the decreased ALFF value around in left superior temporal gyrus, left middle temporal gyrus...
The study provided the evidences that 30min LTE RF-EMF exposure modulated the spontaneous low frequency fluctuations in some brain regions.
