Plain English Summary
Researchers studied the effects of a static magnetic field (SMF, 2 mT) and an extremely low frequency magnetic field (ELF MF, 50 Hz, 2 mT) on neuronal population activity in adult longhorn beetles Morimus funereus. The effects of prolonged and repeated ELF MF exposure on local field potentials were irreversible within the investigated time frame. The researchers did not prove with the methods used that exposure to the SMF for 5 min produces any effects on neuronal population activity.
Why This Matters
The researchers used wavelet analysis of local field potentials to measure changes in neuronal oscillation patterns in the antennal lobe of the beetles. After sine or square ELF MF exposure, the relative wavelet energy (RWE) of the 4–8 Hz frequency band was significantly increased compared to control values. The RWE of slower oscillations in the 1–2 Hz band was significantly decreased after repeated exposures to either sine or square ELF MF. Square ELF MF also induced a decrease in faster waves in the 64–128 Hz range.
