Repeated Head Exposures to a 5G-3.5 GHz Signal Do Not Alter Behavior but Modify Intracortical Gene Expression in Adult Male Mice
Authors not listed · 2025
5G frequencies trigger subtle brain gene changes without behavioral effects, raising questions about long-term cellular impacts.
Plain English Summary
Researchers exposed mice to 5G signals at 3.5 GHz frequency for six weeks, finding no changes in behavior or memory but detecting subtle gene expression changes in brain tissue. The study found less than 1% of brain genes were affected, with changes concentrated in areas handling nerve communication and cellular energy production.
Why This Matters
This study provides important insights into 5G's biological effects at the cellular level. While the researchers found no behavioral changes, the detection of gene expression alterations in brain tissue raises questions about long-term consequences of repeated 5G exposure. The fact that genes related to glutamatergic synapses and mitochondrial function were affected suggests these frequencies can influence fundamental cellular processes, even at relatively low power levels averaging 0.19 W/kg. What's particularly noteworthy is the asymmetrical response between brain hemispheres, with the more heavily exposed right cortex showing distinct mitochondrial gene changes. This demonstrates that even when behavioral effects aren't immediately apparent, biological responses are occurring at the molecular level.
