Millimeter-wave effects on electric activity of crayfish stretch receptors.

View Original AbstractMillimeter waves temporarily altered nerve activity in crayfish through heating effects at power levels 25-250 times higher than typical 5G exposure.
Plain English Summary
Researchers exposed crayfish nerve cells to millimeter-wave radiation (similar to what 5G uses) at power levels up to 250 mW/cm2 and measured changes in nerve firing patterns. They found temporary decreases in nerve activity during exposure that returned to normal afterward, with the effects appearing to be caused by slight heating (about 1.5°C) rather than the electromagnetic fields themselves. This suggests that millimeter waves affect nerve function primarily through thermal heating rather than direct electromagnetic interference.
Study Details
The effects of super high frequency (SHF) microwaves (34-78 GHz) on rates of spontaneous firing of the slowly adapting, stretch-receptor neurons of crayfish were studied.
Initially, irradiation of continuously perfused, fluid-cooled preparations at power densities to 250...
