Over and above frequency: Gamma oscillations as units of neural circuit operations

A Fernandez-Ruiz, A Sirota, V Lopes-dos-Santos… - Neuron, 2023 - cell.com
Summary Gamma oscillations (∼ 30–150 Hz) are widespread correlates of neural circuit
functions. These network activity patterns have been described across multiple animal …

Hippocampal sharp wave‐ripple: A cognitive biomarker for episodic memory and planning

G Buzsáki - Hippocampus, 2015 - Wiley Online Library
Sharp wave ripples (SPW‐Rs) represent the most synchronous population pattern in the
mammalian brain. Their excitatory output affects a wide area of the cortex and several …

[HTML][HTML] The theta-gamma neural code

JE Lisman, O Jensen - Neuron, 2013 - cell.com
Theta and gamma frequency oscillations occur in the same brain regions and interact with
each other, a process called cross-frequency coupling. Here, we review evidence for the …

Neural syntax: cell assemblies, synapsembles, and readers

G Buzsáki - Neuron, 2010 - cell.com
A widely discussed hypothesis in neuroscience is that transiently active ensembles of
neurons, known as" cell assemblies," underlie numerous operations of the brain, from …

Low-intensity electrical stimulation affects network dynamics by modulating population rate and spike timing

Highly energized inhibitory interneurons are a central element for information processing in cortical networks

O Kann, IE Papageorgiou… - Journal of Cerebral …, 2014 - journals.sagepub.com
Gamma oscillations (~ 30 to 100 Hz) provide a fundamental mechanism of information
processing during sensory perception, motor behavior, and memory formation by …

Directional coupling of slow and fast hippocampal gamma with neocortical alpha/beta oscillations in human episodic memory

BJ Griffiths, G Parish, F Roux… - Proceedings of the …, 2019 - National Acad Sciences
Episodic memories hinge upon our ability to process a wide range of multisensory
information and bind this information into a coherent, memorable representation. On a …

The role of the dentate gyrus, CA3a, b, and CA3c for detecting spatial and environmental novelty

MR Hunsaker, JS Rosenberg, RP Kesner - Hippocampus, 2008 - Wiley Online Library
It has been suggested that the dentate gyrus (DG) and CA3 cooperate to efficiently process
spatial information. The DG has been proposed to be important for fine spatial …
