Plain English Summary
Italian researchers exposed mouse brain stem cells to extremely low-frequency electromagnetic fields and found these fields enhanced growth of new brain cells in the hippocampus by switching on genes that promote brain development, potentially opening new therapeutic approaches for memory enhancement.
Why This Matters
This research represents a fascinating twist in EMF science, showing potential beneficial effects rather than harm. However, we need to interpret these findings carefully. The study used isolated stem cells in laboratory conditions with unspecified exposure levels, which may not translate directly to real-world EMF exposure from power lines or household appliances. While the molecular mechanisms identified are intriguing, the leap from enhanced neurogenesis in cell cultures to actual cognitive benefits in living organisms requires substantial additional research. What this study does demonstrate is that EMFs can trigger significant biological responses at the cellular level - reinforcing that these fields are biologically active, not biologically inert as often claimed by industry. Whether everyday ELF exposure levels produce similar effects, and whether such effects are consistently beneficial rather than potentially disruptive to normal brain function, remains an open question requiring further investigation.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
Here, we demonstrate that the ELFEF-dependent enhancement of hippocampal neurogenesis improves spatial learning and memory.

Our results unravel the molecular mechanisms underlying the ELFEFs’ ability to improve endogenous neurogenesis, pointing to histone acetylation–related chromatin remodeling as a critical determinant. These findings could pave the way to the development of novel therapeutic approaches in regenerative medicine.
