Effects of extremely low-frequency magnetic field exposure on cognitive functions: results of a meta-analysis
Authors not listed · 2010
The meta-analysis of nine 50 Hz studies provides little evidence that ELF-MFs affect cognitive functions.
Plain English Summary
Researchers conducted a meta-analysis of nine studies that met minimum design criteria, all using 50 Hz magnetic field exposure. Small but significant effect sizes were found in two cognitive dimensions: exposed subjects performed better on the hard level of visual duration discrimination but worse on the intermediate level. A significant improvement in correct responses was also observed in the flexibility dimension under exposure. However, the authors caution that the small number of studies per dimension makes the estimates unstable and the findings must be treated with extreme caution. Overall, the meta-analysis provides little evidence that ELF-MFs have any effects on cognitive functions.
