Plain English Summary
Scientists exposed mice to cell phone radiation (1.8 GHz) and found it improved memory performance at high exposure levels. The radiation physically changed brain cells and their electrical activity in memory regions, demonstrating that radiofrequency energy can directly alter how the brain functions.
Why This Matters
This study reveals something crucial that the wireless industry would prefer you not know: radiofrequency radiation demonstrably alters brain function, even from a single 30-minute exposure. While the researchers found improved memory rather than impairment, the key finding is that RF radiation physically changed brain cell structure and electrical activity in memory-related regions. The exposure levels (up to 3.3 W/kg SAR) exceeded typical phone use, but the biological changes occurred at levels as low as 2.2 W/kg, which approaches what heavy phone users experience during long calls. The reality is that any biological effect, whether seemingly positive or negative, indicates your brain is responding to this artificial radiation in ways we're only beginning to understand.

Where This Falls on the Concern Scale
Study Details
In this study, we examined the effects of single exposure to 1.8 GHz RF-EMR for 30 min on subsequent recognition memory in mice, using the novel object recognition task (NORT).
RF-EMR exposure at an intensity of >2.2 W/kg specific absorption rate (SAR) power density induced a ...
These results demonstrate that exposure to 1.8 GHz RF-EMR for 30 min can significantly increase recognition memory in mice, and can change dendritic-spine morphology and neuronal excitability in the hippocampus and prefrontal cortex. The SAR in this study (3.3 W/kg) was outside the range encountered in normal daily life, and its relevance as a potential therapeutic approach for disorders associated with recognition memory deficits remains to be clarified.
