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

Spiral wave dynamics in neocortex
Although spiral waves are ubiquitous features of nature and have been observed in many
biological systems, their existence and potential function in mammalian cerebral cortex …

Global waves synchronize the brain's functional systems with fluctuating arousal
We propose and empirically support a parsimonious account of intrinsic, brain-wide
spatiotemporal organization arising from traveling waves linked to arousal. We hypothesize …

Traveling waves in the prefrontal cortex during working memory
S Bhattacharya, SL Brincat, M Lundqvist… - PLoS computational …, 2022 - journals.plos.org
Neural oscillations are evident across cortex but their spatial structure is not well-explored.
Are oscillations stationary or do they form “traveling waves”, ie, spatially organized patterns …

[HTML][HTML] Emergence of complex wave patterns in primate cerebral cortex
Slow brain rhythms are attributed to near-simultaneous (synchronous) changes in activity in
neuron populations in the brain. Because they are slow and widespread, synchronous …

Spiral waves in disinhibited mammalian neocortex
Spiral waves are a basic feature of excitable systems. Although such waves have been
observed in a variety of biological systems, they have not been observed in the mammalian …

A framework for local cortical oscillation patterns
Oscillations are a pervasive feature of neuronal activity in the cerebral cortex. Here, we
propose a framework for understanding local cortical oscillation patterns in cognition: two …

Metastable brain waves
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 …

A parsimonious description of global functional brain organization in three spatiotemporal patterns
Resting-state functional magnetic resonance imaging (MRI) has yielded seemingly
disparate insights into large-scale organization of the human brain. The brain's large-scale …

Theta and alpha oscillations are traveling waves in the human neocortex
Human cognition requires the coordination of neural activity across widespread brain
networks. Here, we describe a new mechanism for large-scale coordination in the human …
