Increased mesiotemporal delta activity characterizes virtual navigation in humans [PDF]

open access: yes, 2013
Hippocampal theta or rhythmic slow activity (RSA) occurring during exploratory behaviors and rapid-eye-movement (REM) sleep is a characteristic and well-identifiable oscillatory rhythm in animals.

Interneuronal mechanisms of hippocampal theta oscillations in a full-scale model of the rodent CA1 circuit

open access: yeseLife, 2016
The hippocampal theta rhythm plays important roles in information processing; however, the mechanisms of its generation are not well understood. We developed a data-driven, supercomputer-based, full-scale (1:1) model of the rodent CA1 area and studied ...

Single-Trial Phase Precession in the Hippocampus [PDF]

open access: yes, 2009
During the crossing of the place field of a pyramidal cell in the rat hippocampus, the firing phase of the cell decreases with respect to the local theta rhythm.

Validating the efficacy of neurofeedback for optimising performance. [PDF]

open access: yes, 2006
The field of neurofeedback training has largely proceeded without validation. Here we review our studies directed at validating SMR, beta and alpha–theta protocols for improving attention, memory, mood and music and dance performance in healthy ...

Novel insights into false recollection : A model of déjà vécu [PDF]

open access: yes, 2010
The thesis of this paper is that deja experiences can be separated into two forms: deja vu, arising from the erroneous sensation of familiarity, and deja vecu, arising from the erroneous sensation of recollection.

Long-term plasticity is proportional to theta-activity. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Theta rhythm in the hippocampal formation is a main feature of exploratory behaviour and is believed to enable the encoding of new spatial information and the modification of synaptic weights.

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.

Long-Term Neurophysiological Outcomes in Patients Undergoing Coronary Artery Bypass Grafting

open access: yesBrazilian Journal of Cardiovascular Surgery, 2021
Introduction: This study aims to evaluate late postoperative neurophysiological outcomes in patients after coronary artery bypass grafting (CABG). Methods: Forty-five male patients with stable coronary artery disease aged 45-69 years underwent extended ...

Abstract Augmented Lazy Theta*: Applying Graph Abstractions to Trajectory Planning with Speed-Limit Constraints [PDF]

open access: yes, 2014
Trajectory planning is a generalisation of path planning in which velocity is also taken into consideration. Considering velocity, in the context of a real-world system such as a robotic vehicle, means considering physical constraints such as the ...
