Blackman, C., S.G. Benane, D. House, AND W. Joines. EFFECTS OF ELF (EXTREMELY LOW FREQUENCY) (1-120 HZ) AND MODULATED (50 HZ) RF (RADIO FREQUENCY) FIELDS ON THE EFFLUX OF CALCIUM IONS FROM BRAIN TISSUE IN VITRO.

Description:
The authors have previously shown that 16-Hz, 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 Vp-p/m. Alternatively, 1-Hz and 30-Hz fields at 40Vp-p/m did not cause enhanced efflux. The authors demonstrate that although there is no enhanced efflux associated with a 42-Hz field at 30,40,50, or 60 Vp-p/m, a 45 Hz field causes enhanced efflux in an intensity range around 40Vp-p/m that is essentially identical to the response observed for 16-Hz fields.
