The brainweb: phase synchronization and large-scale integration

Varela, Francisco, Lachaux, Jean-Philippe, Rodriguez, Eugenio, Martinerie, Jacques·2001·Nature Reviews Neuroscience

Abstract

The emergence of a unified cognitive moment relies on the coordination of scattered mosaics of functionally specialized brain regions. Here we review the mechanisms of large-scale integration that counterbalance the distributed anatomical and functional organization of brain activity to enable the emergence of coherent behaviour and cognition. Although the mechanisms involved in large-scale integration are still largely unknown, we argue that the most plausible candidate is the formation of dynamic links mediated by synchrony over multiple frequency bands.

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?

  • Neural synchrony plays a key role in coordinating brain functions.

    “Neural synchrony thus appears to play a key role in coordinating brain functions.”
  • Time-resolved analyses of functional neuroimaging can identify time-sensitive shifts in inter-areal synchrony, a proposed mechanism for communication between distant brain regions.

    “These experiments provide a sensitive method for non-invasively identifying time-sensitive shifts in inter-areal synchrony, which has been proposed as a key mechanism for effective communication between distant neural regions (Fries, 2015; Varela et al., 2001).”
  • The precise synchronization of neural responses serves the dynamic coordination of distributed neural responses in both local and extended networks.

    “Evidence obtained over the last two decades suggests that the precise synchronization of neural responses serves the dynamic coordination of distributed neural responses in both local and extended networks and is related to a wide range of cognitive and executive processes (Buzsáki and Draguhn, 2004”
  • The precise synchronization of neural responses is related to a wide range of cognitive and executive processes.

  • The CEMI Field Theory serves as the foundation for examining the experimentally observed correlations between synchronized neuronal firing and conscious awareness.

    “The Conscious Electromagnetic Information (CEMI) Field Theory, proposed by Johnjoe McFadden [23], serves as the foundation for examining the experimentally observed correlations between synchronized neuronal firing and conscious awareness [75].”

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.
