Structure and Development of Neuronal Connections in Isogenic Organisms: Cellular Interactions in the Development of the Optic Lamina of Daphnia
Open accessAbstract
Some details of the growth and initial cellular interactions of optic nerve axons were examined in a parthenogenetic clone of Daphnia magna . Results are summarized as follows: ( i ) the final structure of the optic lamina is dependent upon interactions between growing optic nerve fibers and optic lamina neuroblasts closest to the midplane of the animal, which trigger the morphological differentiation of the neuroblasts; the specificity of connections is achieved by well-defined sequences of cell migration in the ganglion; ( ii ) only one of the eight optic nerve axons growing back from each ommatidium in the eye possesses a structure similar to the growth cones seen on termini of nerve fibers growing in vitro; and ( iii ) undifferentiated neuroblasts in the ganglion react to surface contact by this “lead axon” by enveloping the axon in a glial-like relationship.

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.
