Spectral analysis based on neural field theory is used to analyze dynamic connectivity via methods based on the physical eigenmodes that are the building blocks of brain dynamics. These approaches integrate over space instead of averaging over time and thereby greatly reduce or remove the temporal averaging effects, windowing artifacts, and noise at fine spatial scales that have bedeviled the analysis of dynamical functional connectivity (FC). The dependences of FC on dynamics at various… 

It’s about time: Linking dynamical systems with human neuroimaging to understand the brain

It is argued that dynamical systems theory provides the crucial mechanistic framework for characterizing both the brain’s time-varying quality and its partial stability in the face of perturbations, and hence, that this perspective can have a profound impact on the interpretation of human neuroimaging results and their relationship with behavior.

Geometric constraints on human brain function

It is shown that human cortical and subcortical activity, measured with magnetic resonance imaging under spontaneous and diverse task-evoked conditions, can be parsimoniously understood as resulting from excitations of fundamental, resonant modes of the brain’s geometry rather than of its complex inter-regional connectivity, as classically assumed.

Intrinsic macroscale oscillatory modes driving long range functional connectivity detected with ultrafast fMRI

Peaking in power within clear anatomical boundaries, these oscillatory modes point to an emergent systemic property, questioning current assumptions regarding the local origin of oscillations detected in fMRI and providing novel insights into the organizing principles underpinning spontaneous long-range functional connectivity.

Whole-Brain Network Models: From Physics to Bedside

Computational neuroscience has come a long way from its humble origins in the pioneering work of Hodgkin and Huxley. Contemporary computational models of the brain span multiple spatiotemporal



Time–frequency dynamics of resting-state brain connectivity measured with fMRI

Tracking whole-brain connectivity dynamics in the resting state.

It is suggested that the study of time-varying aspects of FC can unveil flexibility in the functional coordination between different neural systems, and that the exploitation of these dynamics in further investigations may improve the understanding of behavioral shifts and adaptive processes.

Importance of self-connections for brain connectivity and spectral connectomics

It is found that omission of fCM self-connections affects both local and long-range connections in eCMs, so they cannot be omitted even when studying the large-scale, and the present results imply that such fCMs must have self-Connections restored before eC Ms can be inferred from them.

Determination of effective brain connectivity from functional connectivity with application to resting state connectivities.

Fundamental field theory insights are used to derive effective brain connectivity matrices from the functional connectivity matrix defined by activity covariances, and it is shown that functional connection Matrices can be used to uncover the existence and strength of connections that are missed from anatomical connection matrices, including interhemispheric connections that is difficult to track with techniques such as diffusion spectrum imaging.

Physical brain connectomics.

The results demonstrate the need to use systematic physical methods to analyze the brain and the potential of such methods to obtain new insights from data, make new predictions for experimental test, and go beyond phenomenological classification to dynamics and mechanisms.
