[Calcium ion binding in somatic nerves during conduction of rhythmic excitation].
Increase of Ca entry upon excitation depended on stimulation frequency and the types of nerves in crab, frog and squid. The amount of absorbed Ca was high in myelinated nerves whereas the velocity of absorption was higher in nonmyelinated nerves. The maximal level of Ca entry during rhythmic excitation was observed in the frog nerve. The data obtained suggest a mechanism of Ca entry in somatic nerves during rhythmic excitation.
