Criticality in the brain: A synthesis of neurobiology, models and cognition
Cognitive function requires the coordination of neural activity across many scales, from
neurons and circuits to large-scale networks. As such, it is unlikely that an explanatory …

[HTML][HTML] Benchmarking of participant-level confound regression strategies for the control of motion artifact in studies of functional connectivity
Since initial reports regarding the impact of motion artifact on measures of functional
connectivity, there has been a proliferation of participant-level confound regression methods …

Changes in global and thalamic brain connectivity in LSD-induced altered states of consciousness are attributable to the 5-HT2A receptor
Background: Lysergic acid diethylamide (LSD) has agonist activity at various serotonin (5-
HT) and dopamine receptors. Despite the therapeutic and scientific interest in LSD, specific …

Global signal regression strengthens association between resting-state functional connectivity and behavior
Global signal regression (GSR) is one of the most debated preprocessing strategies for
resting-state functional MRI. GSR effectively removes global artifacts driven by motion and …

Sources and implications of whole-brain fMRI signals in humans
Whole-brain fMRI signals are a subject of intense interest: variance in the global fMRI signal
(the spatial mean of all signals in the brain) indexes subject arousal, and psychiatric …

Subcortical evidence for a contribution of arousal to fMRI studies of brain activity
Cortical activity during periods of rest is punctuated by widespread, synchronous events in
both electrophysiological and hemodynamic signals, but their behavioral relevance remains …

[HTML][HTML] Hierarchical heterogeneity across human cortex shapes large-scale neural dynamics
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 …

Mitigating head motion artifact in functional connectivity MRI
Participant motion during functional magnetic resonance image (fMRI) acquisition produces
spurious signal fluctuations that can confound measures of functional connectivity. Without …
