Calcium Transient in Presynaptic Terminal of Squid Giant Synapse: Detection with Aequorin

Llinás, R., Blinks, J. R., Nicholson, C.·1972·Science

Abstract

Microinjection of aequorin, a bioluminescent protein sensitive to calcium, into the presynaptic terminal of the squid giant synapse demonstrated an increase in intracellular calcium ion concentration during repetitive synaptic transmission. Although no light flashes synchronous with individual presynaptic action potentials were detected, the results are considered consistent with the hypothesis that entry of calcium into the presynaptic terminal triggers release of the synaptic transmitter substance.

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.
