Abstract

Traveling patterns of neuronal activity—brain waves—have been observed across a breadth of neuronal recordings, states of awareness, and species, but their emergence in the human brain lacks a firm understanding. Here we analyze the complex nonlinear dynamics that emerge from modeling large-scale spontaneous neural activity on a whole-brain network derived from human tractography. We find a rich array of three-dimensional wave patterns, including traveling waves, spiral waves, sources, and sinks. These patterns are metastable, such that multiple spatiotemporal wave patterns are visited in sequence. Transitions between states correspond to reconfigurations of underlying phase flows, characterized by nonlinear instabilities. These metastable dynamics accord with empirical data from multiple imaging modalities, including electrical waves in cortical tissue, sequential spatiotemporal patterns in resting-state MEG data, and large-scale waves in human electrocorticography. By moving the study of functional networks from a spatially static to an inherently dynamic (wave-like) frame, our work unifies apparently diverse phenomena across functional neuroimaging modalities and makes specific predictions for further experimentation.

  • Evidence suggests that neural fluctuations involve multiplicative rather than merely additive noise components, where the variance of the noise depends on the system's state.

    “Evidence suggests that neural fluctuations involve multiplicative rather than merely additive noise components, where the variance of the noise depends on the system’s state (Buice et al. 2010; Roberts et al. 2019).”

    From The myth of the Bayesian brain (2025) · cites this paper as Roberts et al. 2019

    The Discussion (page unavailable) says that most analyses omitted noise and that sustained fluctuations arose from chaotic node dynamics. The Methods, “Neural mass model” (page unavailable), describes added Gaussian white noise with a specified standard deviation, but does not say its variance depends on the system’s state. Searches for multiplicative noise and state-dependent noise variance found no passage supporting that distinction. (LLM, conf=0.76)

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.
