Traveling waves in the prefrontal cortex during working memory. [PDF]

open access: yesPLoS 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 ...

Locally Induced Traveling Waves Generate Globally Observable Traveling Waves. [PDF]

open access: yesJ Neurosci
Cortical 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

Human connectome topology directs cortical traveling waves and shapes frequency gradients [PDF]

open access: yesNature Communications
Traveling 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]

open access: yeseLife, 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 ...

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

open access: yesNature Communications, 2023
Recent analyses have found waves of neural activity traveling across entire visual cortical areas in awake animals. These traveling waves modulate the excitability of local networks and perceptual sensitivity.

Realistic coupling enables flexible macroscopic traveling waves in the mouse cortex [PDF]

open access: yeseLife
Traveling waves are ubiquitous in neuronal systems across different spatial scales. While microscopic and mesoscopic waves are relatively well studied, the emergence of macroscopic traveling waves remains less understood.

Tonotopically arranged traveling waves in the miniature hearing organ of bushcrickets. [PDF]

open access: yesPLoS ONE, 2012
Place based frequency discrimination (tonotopy) is a fundamental property of the coiled mammalian cochlea. Sound vibrations mechanically conducted to the hearing organ manifest themselves into slow moving waves that travel along the length of the organ ...

Spontaneous traveling waves naturally emerge from horizontal fiber time delays and travel through locally asynchronous-irregular states

open access: yesNature Communications, 2021
Spontaneous traveling cortical waves shape neural responses. Using a large-scale computational model, the authors show that transmission delays shape locally asynchronous spiking dynamics into traveling waves without inducing correlations and boost ...

Planar, spiral, and concentric traveling waves distinguish behavioral states in human memory [PDF]

open access: yesNature Communications
A fundamental challenge in neuroscience is explaining how widespread brain regions flexibly interact to support behaviors. We hypothesize that traveling waves of oscillations are a key mechanism of neural coordination, such that they propagate across the

Propofol anesthesia alters cortical traveling waves

open access: yesbioRxiv, 2022
Oscillatory dynamics in cortex seem to organize into traveling waves that serve a variety of functions. Recent studies show that propofol, a widely used anesthetic, dramatically alters cortical oscillations by increasing slow-delta oscillatory power and ...
