Prolonged Ca 2+ -Dependent Afterhyperpolarizations in Hippocampal Neurons of Aged Rats
Abstract
The possibility that calcium is elevated in brain neurons during aging was examined by quantifying afterhyperpolarizations induced by spike bursts in CA1 neurons of hippocampal slices from young and aged rats. The afterhyperpolarizations result from Ca 2+ -dependent K + conductance increases and are blocked in medium low in Ca 2+ and prolonged in medium high in Ca 2+ . The afterhyperpolarization and associated conductance increases were considerably prolonged in cells from aged rats, although inhibitory postsynaptic potentials did not differ with age. Since elevated intracellular Ca 2+ can exert deleterious effects on neurons, the data suggest that altered Ca 2+ homeostasis may play a significant role in normal brain aging.

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.
