โฆ Synopsis
45Ca2+ efflux from neonatal isolated chick brains was measured. The brains were exposed to uniform or nonuniform static magnetic fields. The field intensity ranged from 200-900 mT. The exposure took place during incubation and/or when efflux was being measured. No difference appeared in the 45Ca2+ efflux between controls and exposed brains.

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
