Neurofeedback training improves episodic and semantic long-term memory performance

open access: yesScientific Reports, 2021
Understanding and improving memory are vital to enhance human life. Theta rhythm is associated with memory consolidation and coding, but the trainability and effects on long-term memory of theta rhythm are unknown.

Frequency Characteristics of Rhythm Non-Assimilation in Canine Ventricular Fibrillation

open access: yesОбщая реаниматология, 2010
Ventricular fibrillation is the main cause of sudden cardiac death in many countries, including Russia; therefore to study ventricular fibrillation is an urgent problem.

On the role of theta-driven syllabic parsing in decoding speech: intelligibility of speech with a manipulated modulation spectrum

open access: yesFrontiers in Psychology, 2012
Recent hypotheses on the potential role of neuronal oscillations in speech perception propose that speech is processed on multi-scale temporal analysis windows formed by a cascade of neuronal oscillators locked to the input pseudo-rhythm.

Speed controls the amplitude and timing of the hippocampal gamma rhythm. [PDF]

open access: yesPLoS ONE, 2011
Cortical and hippocampal gamma oscillations have been implicated in many behavioral tasks. The hippocampus is required for spatial navigation where animals run at varying speeds.

Investigation of Theta Rhythm Effect in Detection of Finger Movement. [PDF]

open access: yesJ Exp Neurosci, 2019
Movements cause changes in cortical rhythms emanating from the sensorimotor area. It is known that alpha and beta brainwaves take an important role of motor activity and motor imagery.

A theta rhythm in macaque visual cortex and its attentional modulation. [PDF]

open access: yesProc Natl Acad Sci U S A, 2018
Theta rhythms govern rodent sniffing and whisking, and human language processing. Human psychophysics suggests a role for theta also in visual attention. However, little is known about theta in visual areas and its attentional modulation.

Locomotion-related oscillatory body movements at 6-12 Hz modulate the hippocampal theta rhythm.

open access: yesPLoS ONE, 2011
The hippocampal theta rhythm is required for accurate navigation and spatial memory but its relation to the dynamics of locomotion is poorly understood.

Examining cortical tracking of the speech envelope in post-stroke aphasia

open access: yesFrontiers in Human Neuroscience, 2023
IntroductionPeople with aphasia have been shown to benefit from rhythmic elements for language production during aphasia rehabilitation. However, it is unknown whether rhythmic processing is associated with such benefits.

Coherent theta activity in the medial and orbital frontal cortices encodes reward value

open access: yeseLife, 2021
This study examined how the medial frontal (MFC) and orbital frontal (OFC) cortices process reward information. We simultaneously recorded local field potentials in the two areas as rats consumed liquid sucrose rewards.
