View Original AbstractExposing mollusk neurons to 900-MHz radiation significantly decreased the average latent period of action potentials, while the firing threshold was not changed.
Plain English Summary
Researchers exposed single neurons of a mollusk to electromagnetic fields using a Transverse Electromagnetic Cell to study effects on neuron excitability and memory processes. The specific absorption rate deposited into the single neuron was calculated to be 0.63 W/kg with a temperature increment of 0.1°C. After acute exposure, the average firing threshold of action potentials was not changed, but the average latent period was significantly decreased. The researchers noted that the observed alterations were transient and that only the latent period remained at the changed level.
Why This Matters
The study used a Transverse Electromagnetic Cell to deliver the electromagnetic field to individual mollusk nerve cells, and used a standard microelectrode technique to measure the electrical activity of those neurons. Computational modeling with the Finite-Difference Time-Domain method was used to calculate how the electromagnetic field interacted with the nerve tissue. The researchers suggested that while the threshold and time of habituation might also be altered during exposure, only the latent period remained changed after the acute exposure ended.

Where This Falls on the Concern Scale
Study Details
The goal of the present work was to explore the influence of commercially available cell phone irradiation on the single neuron excitability and memory processes. A Transverse Electromagnetic Cell (TEM Cell) was used to expose single neurons of mollusk to the electromagnetic field.
Finite-Difference Time-Domain (FDTD) method was used for modeling the TEM Cell and the electromagnet...
