Steady magnetic fields mimic the effect of caffeine on neurons.
We have observed that steady magnetic fields (SMF) of 1160 and 2600 gauss (G) mimic the inhibitory and excitatory actions of caffeine on neurons. We had observed that isolated mollusc neurons exposed to SMF were either inhibited or excited by mechanisms that appear Ca2+-dependent. Our results with caffeine corroborate that changes in Ca2+ kinetics underlie the electrophysiological membrane changes observed in neurons exposed to SMF.
