title: A novel, calcium-induced triphasic current response in silent, non-bursting Aplysia neurons.
abstract: The iontophoretic injection of Ca2+ ions into voltage-clamped, silent neurons of Aplysia californica results in a prolonged, triphasic current response. This response consists of: a tetraethylammonium-sensitive outward current during the injection; followed by an inward current 10-30 s after the end of the injection; and finally a long, slowly increasing outward current that lasts for several minutes before returning to baseline.
