Synchronous and asynchronous theta and gamma activity during episodic memory formation
To test the hypothesis that neural oscillations synchronize to mediate memory encoding, we
analyzed electrocorticographic recordings taken as 68 human neurosurgical patients …

Widespread theta synchrony and high-frequency desynchronization underlies enhanced cognition
The idea that synchronous neural activity underlies cognition has driven an extensive body
of research in human and animal neuroscience. Yet, insufficient data on intracranial …

Memory formation by neuronal synchronization
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
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 …

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
Although the hippocampus plays a crucial role in encoding and retrieval of contextually
mediated episodic memories, considerable controversy surrounds the role of the …
