Unequal distribution of calcium and magnesium of snail neuron.
Ca and Mg contents of snail neuron differ depending on the cell type. Ca and Mg near the cell membrane are not equally distributed in the isolated neuron. Ca is almost twice as dense in the axonhillock region than in the cell body. The Mg distribution pattern is the reverse of that of Ca.
