Theta synchronization during episodic retrieval: neural correlates of conscious awareness

W Klimesch, M Doppelmayr, A Yonelinas… - Cognitive Brain …, 2001 - Elsevier
The neural correlates of conscious awareness during successful memory retrieval were
examined. In a recognition test, subjects indicated whether they consciously recollected the …

Theta synchronization and alpha desynchronization in a memory task

W Klimesch, M Doppelmayr, H Schimke… - …, 1997 - Wiley Online Library
In the present study, we examined the hypothesis that episodic encoding and retrieval
processes are primarily reflected by a task‐related increase in theta power. Individuals …

Prestimulus theta activity predicts correct source memory retrieval

RJ Addante, AJ Watrous… - Proceedings of the …, 2011 - National Acad Sciences
Recent evidence indicates that the processing of a stimulus can be influenced by preceding
patterns of brain activity. Here we examine whether prestimulus oscillatory brain activity can …

Episodic retrieval is reflected by a process specific increase in human electroencephalographic theta activity

W Klimesch, M Doppelmayr, W Stadler, D Pöllhuber… - Neuroscience …, 2001 - Elsevier
Is an increase in theta during retrieval due (primarily) to the access of a stored code or to
more general processes? The electroencephalogram was recorded while subjects …

Event-related brain potential correlates of two states of conscious awareness in memory

E Düzel, AP Yonelinas, GR Mangun… - Proceedings of the …, 1997 - National Acad Sciences
We report an event-related potential (ERP) experiment of human recognition memory that
explored the relation between conscious awareness and electrophysiological activity of the …

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
humans is their role for the recollection of personal events. A specific role of theta for …

Theta synchronization in the human EEG and episodic retrieval

M Doppelmayr, W Klimesch, J Schwaiger, P Auinger… - Neuroscience …, 1998 - Elsevier
Event-related desynchronization (ERD) and synchronization (ERS) was measured during
episodic retrieval in a specially designed recognition task which forces subjects to avoid …

Episodic and semantic memory: an analysis in the EEG theta and alpha band

W Klimesch, H Schimke, J Schwaiger - … and clinical Neurophysiology, 1994 - Elsevier
This study examines the hypothesis that in contrast to semantic memory processes that are
assumed to be reflected primarily within the alpha band, episodic memory processes are …

Electrophysiological evidence for the influence of unitization on the processes engaged during episodic retrieval: Enhancing familiarity based remembering

SM Rhodes, DI Donaldson - Neuropsychologia, 2007 - Elsevier
Episodic memory depends upon multiple dissociable retrieval processes. Here we
investigated the degree to which the processes engaged during successful retrieval are …

Medial temporal theta state before an event predicts episodic encoding success in humans

S Guderian, BH Schott… - Proceedings of the …, 2009 - National Acad Sciences
We report a human electrophysiological brain state that predicts successful memory for
events before they occur. Using magnetoencephalographic recordings of brain activity …
