Abstract

Inactivation of the Ca channel of Aplysia neurons was studied in the absence of potassium current in cells that were cesium-loaded with the aid of the ionophore nystatin. Inactivation was substantially decreased by methods that limited Ca entry. Depolarizations commensurate with the equilibrium potential of Ca resulted in minimal inactivation. Replacement of extracellular Ca by Ba also decreased inactivation. It is concluded that inactivation of the Ca channel is a function of the extent of Ca entry rather than membrane potential, thus differing fundamentally from the purely voltage-dependent mechanism for sodium inactivation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
