Altered Synaptic Plasticity in Drosophila Memory Mutants with a Defective Cyclic AMP Cascade
Abstract
Synaptic transmission was examined in Drosophila mutants deficient in memory function. These mutants, dunce and rutabaga , are defective in different steps of the cyclic adenosine 3′,5′-monophosphate (cAMP) cascade. In both dunce and rutabaga larvae, voltage-clamp analysis of neuromuscular transmission revealed impaired synaptic facilitation and post-tetanic potentiation as well as abnormal responses to direct application of dibutyryl cAMP. In addition, the calcium dependence of transmitter release was shifted in dunce . The results suggest that the cAMP cascade plays a role in synaptic facilitation and potentiation and indicate that synaptic plasticity is altered in Drosophila memory mutants.

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.
