Interacting spiral wave patterns underlie complex brain dynamics and are related to cognitive processing

Y Xu, X Long, J Feng, P Gong - Nature human behaviour, 2023 - nature.com
The large-scale activity of the human brain exhibits rich and complex patterns, but the
spatiotemporal dynamics of these patterns and their functional roles in cognition remain …

Metastable brain waves

JA Roberts, LL Gollo, RG Abeysuriya, G Roberts… - Nature …, 2019 - nature.com
Traveling patterns of neuronal activity—brain waves—have been observed across a breadth
of neuronal recordings, states of awareness, and species, but their emergence in the human …

Waves traveling over a map of visual space can ignite short-term predictions of sensory input

GB Benigno, RC Budzinski, ZW Davis… - Nature …, 2023 - nature.com

areas in awake animals. These traveling waves modulate the excitability of local networks …

Detection and analysis of spatiotemporal patterns in brain activity

RG Townsend, P Gong - PLoS computational biology, 2018 - journals.plos.org
There is growing evidence that population-level brain activity is often organized into
propagating waves that are structured in both space and time. Such spatiotemporal patterns …

Development of top-down cortical propagations in youth

A Pines, AS Keller, B Larsen, M Bertolero, A Ashourvan… - Neuron, 2023 - cell.com
Hierarchical processing requires activity propagating between higher-and lower-order
cortical areas. However, functional neuroimaging studies have chiefly quantified fluctuations …

Visual evoked feedforward–feedback traveling waves organize neural activity across the cortical hierarchy in mice

A Aggarwal, C Brennan, J Luo, H Chung… - Nature …, 2022 - nature.com
Sensory processing is distributed among many brain regions that interact via feedforward
and feedback signaling. Neuronal oscillations have been shown to mediate intercortical …

A spatiotemporal energy model based on spiking neurons for human motion perception

H Yedjour, D Yedjour - Cognitive Neurodynamics, 2024 - Springer
Inspired by the motion processing pathway, this paper proposes a bio-inspired feedforward
spiking network model based on Hodgkin–Huxley neurons for human motion perception …

[HTML][HTML] Enhancing visual motion discrimination by desynchronizing bifocal oscillatory activity

RF Salamanca-Giron, E Raffin, SB Zandvliet, M Seeber… - NeuroImage, 2021 - Elsevier
Visual motion discrimination involves reciprocal interactions in the alpha band between the

Rich-club connectivity, diverse population coupling, and dynamical activity patterns emerging from local cortical circuits

Y Gu, Y Qi, P Gong - PLoS computational biology, 2019 - journals.plos.org
Experimental studies have begun revealing essential properties of the structural connectivity
and the spatiotemporal activity dynamics of cortical circuits. To integrate these properties …

Cortex-wide spontaneous activity non-linearly steers propagating sensory-evoked activity in awake mice

M Liu, Y Liang, C Song, T Knöpfel, C Zhou - Cell Reports, 2022 - cell.com
The brain responds highly variably to identical sensory inputs, but there is no consensus on
the nature of this variability. We explore this question using cortex-wide optical voltage …
