From the connectome to brain function

Bargmann, Cornelia I, Marder, Eve·2013·Nature Methods

Abstract

In this Historical Perspective, we ask what information is needed beyond connectivity diagrams to understand the function of nervous systems. Informed by invertebrate circuits whose connectivities are known, we highlight the importance of neuronal dynamics and neuromodulation, and the existence of parallel circuits. The vertebrate retina has these features in common with invertebrate circuits, suggesting that they are general across animals. Comparisons across these systems suggest approaches to study the functional organization of large circuits based on existing knowledge of small circuits.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The model used naive estimates of synaptic weights from the simple measure of number of synapses, simplified linear rate model neuron treatment of cell morphology, synaptic and intrinsic cellular biophysics, and neglected possible neuromodulatory effects.

    “This is especially so given our naive estimates of synaptic weights from the simple measure of number of synapses, simplified linear rate model neuron treatment of cell morphology, synaptic and intrinsic cellular biophysics and neglect of possible neuromodulatory effects64.”
  • Studies of the connectomes of C. elegans and the crustacean stomatogastric ganglion demonstrate that connectivity knowledge constrains, but does not dictate, a particular circuit mechanism.

    “Moreover, studies of the connectomes of C. elegans and the crustacean stomatogastric ganglion demonstrate that connectivity knowledge constrains, but does not dictate, a particular circuit mechanism56–58.”
  • The same neuron or circuit can exhibit different input-output responses and plasticity depending on a global circuit state, as reflected by the concentrations of various neuromodulators.

    “The same neuron or circuit can exhibit different input-output responses and plasticity depending on a global circuit state, as reflected by the concentrations of various neuromodulators like dopamine, serotonin, norepinephrine, acetylcholine, and hundreds of different neuropeptides such as opiods (Bargmann, 2012; Bargmann and Marder, 2013).”

  • A single neural circuit can be thought of as multiple overlapping circuits with modulation switching between them.

    “Furthermore, it has been argued that a single neural circuit can be thought of as multiple overlapping circuits with modulation switching between them (Bargmann, 2012; Bargmann and Marder, 2013).”

  • These modulators interact in complex and cell-type-specific ways to influence circuit function.

    “These modulators interact in complex and cell-type-specific ways to influence circuit function.”

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.
