[Effect of a series of small amplitude magnetic field pulses on the electrical activity of mollusk neurons].

Possibility of summing up in time the effects of small values of impulses of 1 Oe magnitude magnetic field (MF) on the electrical activity (EA) of Lymnaea stagnalis neurons was studied. The single impulse of MF did not cause changes in neurons EA. EA changes took place under the action of 5-8 impulses of MF. The neuron reaction has a threshold nature dependent on the number of applied impulses.
