Synaptic Vesicles: Selective Depletion in Crayfish Excitatory and Inhibitory Axons

Atwood, Harold L., Lang, Fred, Morin, Walter A.·1972·Science

Abstract

Stimulation of the excitatory axon of the opener muscle of the crayfish in the presence of the metabolic inhibitor 2,4-dinitrophenol leads to depletion of synaptic vesicles in nerve terminals containing round vesicles. Stimulation of the inhibitory axon under these conditions produces depletion of vesicles in other nerve terminals containing more elongate synaptic vesicles. The experiments show that terminals with round synaptic vesicles are excitatory and that terminals with elongate synaptic vesicles are inhibitory. Replenishment of synaptic vesicles appears to require metabolic energy.

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.
