[The effect of a magnesium-free solution on the parameters of the spontaneous excitatory postsynaptic potentials in identified snail neurons].
This investigation has revealed that application of magnesium-free medium to snail brain preparation changes the parameters of excitatory input to the identified neurons of the snail: the distribution of amplitude and intervals between EPSP. The other parameters (time to peak level and duration of EPSP) remained unaltered. It is concluded that spontaneous firing activity of initially silent neurons in magnesium-free solution develops as a result of increased efficiency of excitatory input.
