Plain English Summary
Researchers exposed rats to UMTS cell phone signals at different power levels to study effects on memory formation in the brain. They found no impact on memory-related brain activity at 2 W/kg (similar to phone use), but significant disruption at 10 W/kg (five times higher than typical exposure). The study suggests current cell phone radiation levels may not harm memory processes, but much higher exposures could be problematic.
Study Details
In the present study we applied radio-frequency (RF) signals of the Universal Mobile Telecommunications System (UMTS) to full brain exposed male Wistar rats in order to elaborate putative influences on stress hormone release (corticosteron; CORT and adrenocorticotropic hormone; ACTH) and on hippocampal derived synaptic long-term plasticity (LTP) and depression (LTD) as electrophysiological hallmarks for memory storage and memory consolidation.
Exposure was computer controlled providing blind conditions. Nominal brain-averaged specific absorpt...

Our findings suggest that UMTS exposure with SAR in the range of 2 W/kg is not harmful to critical markers for memory storage and memory consolidation, however, an influence of UMTS at high energy absorption rates (10 W/kg) cannot be excluded.
