[HTML][HTML] Geometric constraints on human brain function
The anatomy of the brain necessarily constrains its function, but precisely how remains
unclear. The classical and dominant paradigm in neuroscience is that neuronal dynamics are …

Bistability and non-Gaussian fluctuations in spontaneous cortical activity
The brain is widely assumed to be a paradigmatic example of a complex, self-organizing
system. As such, it should exhibit the classic hallmarks of nonlinearity, multistability, and “…

Dynamical consequences of regional heterogeneity in the brain's transcriptional landscape
Brain regions vary in their molecular and cellular composition, but how this heterogeneity
shapes neuronal dynamics is unclear. Here, we investigate the dynamical consequences of …

[HTML][HTML] Identifying and removing widespread signal deflections from fMRI data: Rethinking the global signal regression problem
One of the most controversial procedures in the analysis of resting-state functional magnetic
resonance imaging (rsfMRI) data is global signal regression (GSR): the removal, via linear …

[HTML][HTML] Genetic influences on hub connectivity of the human connectome
Brain network hubs are both highly connected and highly inter-connected, forming a critical
communication backbone for coherent neural dynamics. The mechanisms driving this …

Eigenmodes of brain activity: Neural field theory predictions and comparison with experiment
PA Robinson, X Zhao, KM Aquino, JD Griffiths… - NeuroImage, 2016 - Elsevier
Neural field theory of the corticothalamic system is applied to predict and analyze the activity
eigenmodes of the bihemispheric brain, focusing particularly on their spatial structure. The …

Modeling spatial, developmental, physiological, and topological constraints on human brain connectivity
The complex connectivity of nervous systems is thought to have been shaped by competitive
selection pressures to minimize wiring costs and support adaptive function. Accordingly, …

[HTML][HTML] Hemodynamic traveling waves in human visual cortex
Functional MRI (fMRI) experiments rely on precise characterization of the blood oxygen
level dependent (BOLD) signal. As the spatial resolution of fMRI reaches the sub-millimeter …

Relationships between neuronal oscillatory amplitude and dynamic functional connectivity
Event-related fluctuations of neural oscillatory amplitude are reported widely in the context
of cognitive processing and are typically interpreted as a marker of brain “activity”. However, …

Two spatially distinct posterior alpha sources fulfill different functional roles in attention
Directing attention helps to extract relevant information and suppress distracters. Alpha
brain oscillations (8–12 Hz) are crucial for this process, with power decreases facilitating …
