## Abstract Changes have been found in calciumβion binding to brain tissue exposed in vitro to a specific power density (0.83 mW/cm^2^) of 147βMHz radiation, amplitude modulated by a 16βHz sine wave. This report replicates and extends this previous work. To define more precisely the range of effect

## Abstract To explain a carrier frequency dependence reported for radiofrequency (RF)βinduced calciumβion efflux from brain tissue, a chickβbrain hemisphere bathed in buffer solution is modeled as a sphere within the uniform field of the incident electromagnetic wave. Calculations on a spherical m
We have previously shown that 16-H~. sinusoidal electromagnetic fields can cause enhanced efflux of calcium ions from chick brain tissue, in vitro, in two intensity regions centered on 6 and 40 V,~,/m. Alternatively, I-Hz and 30-Hz fields at 40 V,.,/m did not cause enhanced efflux. We now demonstrat
The frequency dependence of electromagnetic field-induced calcium-ion efflux from chicken brain tissues has been examined at 15-Hz intervals over the range 1-510 Hz. The electric field component was 15 Vrms/m and the magnetic component varied between 59 and 69 nTrms. No patterns of response as a fun
