Traveling waves in the prefrontal cortex during working memory. [PDF]
PLoS Computational Biology, 2022 Neural oscillations are evident across cortex but their spatial structure is not well- explored. Are oscillations stationary or do they form "traveling waves", i.e., spatially organized patterns whose peaks and troughs move sequentially across cortex ...

Human connectome topology directs cortical traveling waves and shapes frequency gradients [PDF]
Nature CommunicationsTraveling waves and neural oscillation frequency gradients are pervasive in the human cortex. While the direction of traveling waves has been linked to brain function and dysfunction, the factors that determine this direction remain elusive.

Spontaneous neuronal oscillations in the human insula are hierarchically organized traveling waves [PDF]
eLife, 2022 The insula plays a fundamental role in a wide range of adaptive human behaviors, but its electrophysiological dynamics are poorly understood. Here, we used human intracranial electroencephalographic recordings to investigate the electrophysiological ...

Locally Induced Traveling Waves Generate Globally Observable Traveling Waves. [PDF]
J NeurosciCortical traveling waves have been proposed as a fundamental mechanism for neural communication and computation. Methodological uncertainties currently limit the interpretability of noninvasive, extracranial traveling wave data, sparking debates about their cortical origin. Studies using EEG or MEG typically report waves that cover

Programmable double traveling waves in living liquid crystals [PDF]
Nature CommunicationsTraveling patterns are ubiquitous in nature. Controlling the traveling waves in living active matter systems remains elusive due to their intrinsic chaotic nonequilibrium nature. Here, we show how to control the traveling waves in living liquid crystals (

Modulation of motor excitability reflects traveling waves of neural oscillations [PDF]
Cell ReportsSummary: Neural traveling waves represent an important endogenous phenomenon with structural and functional relevance in the human brain. These waves, commonly recorded via electroencephalogram (EEG) or electrocorticography (ECoG), are implicated in a ...

Cortical traveling waves reflect state-dependent hierarchical sequencing of local regions in the human connectome network [PDF]
Scientific Reports, 2022 Recent human studies using electrocorticography have demonstrated that alpha and theta band oscillations form traveling waves on the cortical surface.
