The properties of the Ca2+ channels mediating transmitter release in vertebrate neurons have not yet been described with voltage-clamp techniques. Several types of voltage-dependent Ca2+ channels are known to exist on neuronal somata, but the small size and inaccessibility of most vertebrate nerve endings have precluded direct characterization of the presynaptic channels. However, large nerve endings, which release the peptides oxytocin and vasopressin in a Ca2(+)-dependent manner, can be… CONTINUE READING
