JF Burke, KA Zaghloul, J Jacobs… - Journal of …, 2013 - Soc Neuroscience
To test the hypothesis that neural oscillations synchronize to mediate memory encoding, we
analyzed electrocorticographic recordings taken as 68 human neurosurgical patients …

[HTML][HTML] Widespread theta synchrony and high-frequency desynchronization underlies enhanced cognition

EA Solomon, JE Kragel, MR Sperling, A Sharan… - Nature …, 2017 - nature.com
The idea that synchronous neural activity underlies cognition has driven an extensive body

Memory processes, brain oscillations and EEG synchronization

W Klimesch - International journal of psychophysiology, 1996 - Elsevier
This article tries to integrate results in memory research from divergent disciplines such as
cognitive psychology, neuroanatomy, and neurophysiology. The integrating link is seen in …

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 …

Memory formation by neuronal synchronization

N Axmacher, F Mormann, G Fernández, CE Elger… - Brain research …, 2006 - Elsevier
Cognitive functions not only depend on the localization of neural activity, but also on the
precise temporal pattern of activity in neural assemblies. Synchronization of action potential …

Single-trial phase entrainment of theta oscillations in sensory regions predicts human associative memory performance

D Wang, A Clouter, Q Chen, KL Shapiro… - Journal of …, 2018 - Soc Neuroscience
Episodic memories are rich in sensory information and often contain integrated information
from different sensory modalities. For instance, we can store memories of a recent concert …

Human neocortical oscillations exhibit theta phase differences between encoding and retrieval

DS Rizzuto, JR Madsen, EB Bromfield… - Neuroimage, 2006 - Elsevier
We analyzed intracranial brain activity recorded from human participants during the
performance of a working-memory task. We show that 6–13 Hz activity exhibits consistent …

Induced theta oscillations mediate large‐scale synchrony with mediotemporal areas during recollection in humans

S Guderian, E Düzel - Hippocampus, 2005 - Wiley Online Library
One functional aspect of theta oscillations that recent studies have begun to explore in

The role of theta-range oscillations in synchronising and integrating activity in distributed mnemonic networks

IJ Kirk, JC Mackay - Cortex, 2003 - Elsevier
It is well established that the occurrence of theta rhythm in the hippocampus is important in a
variety of mnemonic tasks. However, in this review it will be argued that theta-rhythmic …

Hippocampal gamma oscillations increase with memory load

MK Van Vugt, A Schulze-Bonhage, B Litt… - Journal of …, 2010 - Soc Neuroscience
