Brain states as wave-like motifs

M Foster, D Scheinost - Trends in Cognitive Sciences, 2024 - cell.com
There is ample evidence of wave-like activity in the brain at multiple scales and levels. This
emerging literature supports the broader adoption of a wave perspective of brain activity …

Phantom oscillations in principal component analysis

M Shinn - Proceedings of the National Academy of …, 2023 - National Acad Sciences
Principal component analysis (PCA) is a dimensionality reduction method that is known for
being simple and easy to interpret. Principal components are often interpreted as low …

Intrinsic macroscale oscillatory modes driving long range functional connectivity in female rat brains detected by ultrafast fMRI

J Cabral, FF Fernandes, N Shemesh - Nature Communications, 2023 - nature.com
Spontaneous fluctuations in functional magnetic resonance imaging (fMRI) signals correlate
across distant brain areas, shaping functionally relevant intrinsic networks. However, the …

Local orchestration of distributed functional patterns supporting loss and restoration of consciousness in the primate brain

AI Luppi, L Uhrig, J Tasserie, CM Signorelli… - Nature …, 2024 - nature.com

cortex. While the direction of traveling waves has been linked to brain function and …

In vivo whole-cortex marker of excitation-inhibition ratio indexes cortical maturation and cognitive ability in youth

S Zhang, B Larsen, VJ Sydnor, T Zeng… - Proceedings of the …, 2024 - National Acad Sciences
A balanced excitation-inhibition ratio (E/I ratio) is critical for healthy brain function. Normative
development of cortex-wide E/I ratio remains unknown. Here, we noninvasively estimate a …

[HTML][HTML] Disruptions of hierarchical cortical organization in early psychosis and schizophrenia

A Holmes, PT Levi, YC Chen, S Chopra… - Biological Psychiatry …, 2023 - Elsevier
Background The cerebral cortex is organized hierarchically along an axis that spans
unimodal sensorimotor to transmodal association areas. This hierarchy is often …

Modular subgraphs in large-scale connectomes underpin spontaneous co-fluctuation events in mouse and human brains

E Ragone, J Tanner, Y Jo, F Zamani Esfahlani… - Communications …, 2024 - nature.com
Previous studies have adopted an edge-centric framework to study fine-scale network
dynamics in human fMRI. To date, however, no studies have applied this framework to data …
