Abstract

Formation of myelin, the electrical insulation on axons produced by oligodendrocytes, is controlled by complex cell-cell signaling that regulates oligodendrocyte development and myelin formation on appropriate axons. If electrical activity could stimulate myelin induction, then neurodevelopment and the speed of information transmission through circuits could be modified by neural activity. We find that release of glutamate from synaptic vesicles along axons of mouse dorsal root ganglion neurons in culture promotes myelin induction by stimulating formation of cholesterol-rich signaling domains between oligodendrocytes and axons, and increasing local synthesis of the major protein in the myelin sheath, myelin basic protein, through Fyn kinase-dependent signaling. This axon-oligodendrocyte signaling would promote myelination of electrically active axons to regulate neural development and function according to environmental experience.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Both intrinsic and extrinsic factors influence myelination.

    “Both intrinsic and extrinsic factors have been shown to influence myelination. For example, recent studies have shown that electrical activity drives myelination (Gibson et al., 2014; Ishibashi et al., 2006; Wake et al., 2011) and that synaptogenesis and myelination are linked.”

    From Down Syndrome Developmental Brain Transcriptome Reveals Defective Oligodendrocyte Differentiation and Myelination (2016) · cites this paper as Wake et al., 2011

    The paper reports that axonal electrical activity promotes myelin induction in mouse neuron–oligodendrocyte cultures, supporting the electrical-activity example for which it is cited. It also says the mechanism must be confirmed in vivo, so the unqualified statement that electrical activity drives myelination extends beyond what this study establishes. (LLM, conf=0.83)

  • Electrical activity drives myelination.

    “For example, recent studies have shown that electrical activity drives myelination (Gibson et al., 2014; Ishibashi et al., 2006; Wake et al., 2011) and that synaptogenesis and myelination are linked.”

    From Down Syndrome Developmental Brain Transcriptome Reveals Defective Oligodendrocyte Differentiation and Myelination (2016) · cites this paper as Wake et al., 2011

    The supplied paper text (labeled Abstract; page not provided) reports that electrical stimulation increased myelin induction in neuron–oligodendrocyte cultures, with increased myelination persisting after 16 days. It also says the mechanisms must be confirmed in vivo, so the unqualified claim that electrical activity drives myelination extends beyond the demonstrated culture setting. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Synaptogenesis and myelination are linked.

    “For example, recent studies have shown that electrical activity drives myelination (Gibson et al., 2014; Ishibashi et al., 2006; Wake et al., 2011) and that synaptogenesis and myelination are linked.”
  • Neuronal activity-dependent myelination changes have been observed in cell culture and in vivo experiments.

    “Neuronal activity-dependent changes in myelination have been observed in cell culture (Wake et al., 2011; Fields, 2010) as well as in recent in vivo experiments (Gibson et al., 2014).”

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.
