Theta frequency (4–8 Hz) fluctuations of the local field potential have long been implicated
in learning and memory. Human studies of episodic memory, however, have provided mixed …

Oscillatory fluctuations of local field potentials (LFPs) in the theta (4–8Hz) and gamma (25–
140Hz) band are held to play a mechanistic role in various aspects of memory including the …

Recent physiological studies have implicated theta—a high-amplitude 4–8 Hz oscillation
that is prominent in rat hippocampus during locomotion, orienting and other voluntary …

Memory formation and reinstatement are thought to lock to the hippocampal theta rhythm,
predicting that encoding and retrieval processes appear rhythmic themselves. Here, we …

Recent findings are reviewed indicating that upper alpha oscillations-when analyzed with
appropriate time/frequency resolution-show a similar physiological reactivity as theta in …

Recent research indicates that an increase in theta band power is related to episodic
memory performance. In this study with human subjects, the evoked (time locked) and …

The importance of the hippocampal theta oscillation (4–8 Hz) to memory formation has been
well‐established through studies in animals, prompting researchers to propose …

Cortical theta appears important in sensory processing and memory. Intracanial electrode
recordings provide a high spatial resolution method for studying such oscillations during …

Recent studies suggest that human theta oscillations appear to be functionally associated
with memory processes. It is less clear, however, to what type of memory sub-processes …

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 …
