Cholinergic Regulation of Hippocampal Theta Rhythm [PDF]

open access: yesBiomedicines, 2022
Cholinergic regulation of hippocampal theta rhythm has been proposed as one of the central mechanisms underlying hippocampal functions including spatial memory encoding.

Pedunculopontine-stimulation obstructs hippocampal theta rhythm and halts movement [PDF]

open access: yesScientific Reports
While the movement of rodents can be paused by optogenetic stimulation of a brainstem nucleus, the pedunculopontine nucleus (PPN), it is unknown whether this response has a functional purpose.

Interictal Spike and Loss of Hippocampal Theta Rhythm Recorded by Deep Brain Electrodes during Epileptogenesis [PDF]

open access: yesSensors, 2022
Epileptogenesis is the gradual dynamic process that progressively led to epilepsy, going through the latent stage to the chronic stage. During epileptogenesis, how the abnormal discharges make theta rhythm loss in the deep brain remains not clear.

Knitting induced fronto-central theta rhythm [PDF]

open access: yesEpilepsy & Behavior Reports, 2019
Fronto-central theta rhythms on EEG have been associated with cognitive tasks requiring attention and concentration, such as mental arithmetic or geometric construction.

Medial septal cholinergic mediation of hippocampal theta rhythm induced by vagal nerve stimulation. [PDF]

open access: yesPLoS ONE, 2018
BACKGROUND:Electrical vagal nerve stimulation (VNS) has been used for years to treat patients with drug-resistant epilepsy. This technique also remains under investigation as a specific treatment of patients with Alzheimer's disease.

Phase relations of interneuronal activity relative to theta rhythm [PDF]

open access: yesFrontiers in Neural Circuits, 2023
The theta rhythm plays a crucial role in synchronizing neural activity during attention and memory processes. However, the mechanisms behind the formation of neural activity during theta rhythm generation remain unknown.

A Hypothesis for Theta Rhythm Frequency Control in CA1 Microcircuits [PDF]

open access: yesFrontiers in Neural Circuits, 2021
Computational models of neural circuits with varying levels of biophysical detail have been generated in pursuit of an underlying mechanism explaining the ubiquitous hippocampal theta rhythm.

Decision Time, Slow Inhibition, and Theta Rhythm [PDF]

open access: yesThe Journal of Neuroscience, 2010
In this paper, we examine decision making in a spiking neuronal network and show that longer time constants for the inhibitory neurons can decrease the reaction times and produce theta rhythm. We analyze the mechanism and find that the spontaneous firing rate before the decision cues are applied can drift, and thereby influence the speed of the ...

Nonlinear properties of the brain theta rhythm [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
The purpose of this study is to identify nonlinearity of local brain field potential signals during theta rhythm. Methods. The nonlinearity in the signal is manifested in the synchronous behavior of the fundamental frequency and its higher harmonics; to

Young infants process prediction errors at the theta rhythm

open access: yesNeuroImage, 2021
Examining how young infants respond to unexpected events is key to our understanding of their emerging concepts about the world around them. From a predictive processing perspective, it is intriguing to investigate how the infant brain responds to ...
