Functional and Effective Connectivity: A Review

Friston, Karl J.·2011·Brain Connectivity

Abstract

Over the past 20 years, neuroimaging has become a predominant technique in systems neuroscience. One might envisage that over the next 20 years the neuroimaging of distributed processing and connectivity will play a major role in disclosing the brain's functional architecture and operational principles. The inception of this journal has been foreshadowed by an ever-increasing number of publications on functional connectivity, causal modeling, connectomics, and multivariate analyses of distributed patterns of brain responses. I accepted the invitation to write this review with great pleasure and hope to celebrate and critique the achievements to date, while addressing the challenges ahead.

Recomputing p-values needs the paper’s full text.

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?

  • There is now a large movement in neuroimaging studies toward viewing functional integration or connectivity, superseding functional segregation and the localizationist viewpoint.

    “In short, there is now a large movement in neuroimaging studies toward viewing the functional integration or connectivity, superseding functional segregation and the localizationist viewpoint.41”
  • Two notions are essential to the brain's functional organization: functional segregation and integration.

    “Two notions are essential to the brain’s functional organization: functional segregation and integration (91).”
  • Many factors other than the direct anatomical node-to-node connection true strength can affect correlation coefficients, including variations in signal amplitude and noise level.

    “many factors other than the direct anatomical node-to-node connection “true strength” can affect correlation coefficients, including variations in signal amplitude and noise level [48].”

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.
