Neurodegenerative diseases are the most common cause of dementia. Although their
underlying molecular pathologies have been identified, there is substantial heterogeneity in …

The brain is a complex, multiscale dynamical system composed of many interacting regions.
Knowledge of the spatiotemporal organization of these interactions is critical for establishing …

We propose and empirically support a parsimonious account of intrinsic, brain-wide
spatiotemporal organization arising from traveling waves linked to arousal. We hypothesize …

The posterior cingulate cortex (PCC) is one of the least understood regions of the cerebral
cortex. By contrast, the anterior cingulate cortex has been the subject of intensive …

The large-scale organization of dynamical neural activity across cortex emerges through
long-range interactions among local circuits. We hypothesized that large-scale dynamics are …

A key principle of brain organization is the functional integration of brain regions into
interconnected networks. Functional MRI scans acquired at rest offer insights into functional …

Functional connectivity (FC), or the statistical interdependence of blood-oxygen dependent
level (BOLD) signals between brain regions using fMRI, has emerged as a widely used tool …

We present both a scientific overview and conceptual positions concerning the challenges
and assets of electrophysiological measurements in the search for the nature and functions …

Slow changes in systemic brain physiology can elicit large fluctuations in fMRI time series,
which manifest as structured spatial patterns of temporal correlations between distant brain …

The finding of reduced functional MRI (fMRI) activity in the default mode network (DMN)
during externally focused cognitive control has been highly influential to our understanding …
