Recurrent dynamics in the cerebral cortex: Integration of sensory evidence with stored knowledge

W Singer - Proceedings of the National Academy of …, 2021 - National Acad Sciences
Current concepts of sensory processing in the cerebral cortex emphasize serial extraction
and recombination of features in hierarchically structured feed-forward networks in order to …

Entropy and the brain: An overview

S Keshmiri - Entropy, 2020 - mdpi.com
Entropy is a powerful tool for quantification of the brain function and its information
processing capacity. This is evident in its broad domain of applications that range from …

Global waves synchronize the brain's functional systems with fluctuating arousal

RV Raut, AZ Snyder, A Mitra, D Yellin, N Fujii… - Science …, 2021 - science.org
We propose and empirically support a parsimonious account of intrinsic, brain-wide
spatiotemporal organization arising from traveling waves linked to arousal. We hypothesize …

Wave-like dopamine dynamics as a mechanism for spatiotemporal credit assignment

AA Hamid, MJ Frank, CI Moore - Cell, 2021 - cell.com
Significant evidence supports the view that dopamine shapes learning by encoding reward
prediction errors. However, it is unknown whether striatal targets receive tailored dopamine …

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 …

Theta and alpha oscillations are traveling waves in the human neocortex

H Zhang, AJ Watrous, A Patel, J Jacobs - Neuron, 2018 - cell.com
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 …

Brain-wide interactions during hippocampal sharp wave ripples

N Nitzan, R Swanson, D Schmitz… - Proceedings of the …, 2022 - National Acad Sciences
During periods of disengagement from the environment, transient population bursts, known
as sharp wave ripples (SPW-Rs), occur sporadically. While numerous experiments have …

The ascending arousal system shapes neural dynamics to mediate awareness of cognitive states

BR Munn, EJ Müller, G Wainstein, JM Shine - Nature communications, 2021 - nature.com
Abstract Models of cognitive function typically focus on the cerebral cortex and hence
overlook functional links to subcortical structures. This view does not consider the role of the …

Cytoelectric coupling: Electric fields sculpt neural activity and “tune” the brain's infrastructure

DA Pinotsis, G Fridman, EK Miller - Progress in Neurobiology, 2023 - Elsevier
We propose and present converging evidence for the Cytoelectric Coupling Hypothesis:
Electric fields generated by neurons are causal down to the level of the cytoskeleton. This …

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 …
