Analysis of electroencephalography brain rhythms in the reading process

open access: yesEinstein (São Paulo), 2020
Objective: To verify if, by three distinct quantifiers, the measured electroencephalographic signal at rest is different from the signal measured during a word reading situation, especially considering the faster rhythms, gamma and high-gamma, as it ...

Interacting rhythms enhance sensitivity of target detection in a fronto-parietal computational model of visual attention

open access: yeseLife, 2023
Even during sustained attention, enhanced processing of attended stimuli waxes and wanes rhythmically, with periods of enhanced and relatively diminished visual processing (and subsequent target detection) alternating at 4 or 8 Hz in a sustained visual ...

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.

Neurosystems: brain rhythms and cognitive processing [PDF]

open access: yes, 2013
Neuronal rhythms are ubiquitous features of brain dynamics, and are highly correlated with cognitive processing. However, the relationship between the physiological mechanisms producing these rhythms and the functions associated with the rhythms remains ...

Exploring EEG Features in Cross-Subject Emotion Recognition [PDF]

open access: yes, 2018
Recognizing cross-subject emotions based on brain imaging data, e.g., EEG, has always been difficult due to the poor generalizability of features across subjects.

Decision time, slow inhibition, and theta rhythm [PDF]

open access: yes, 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

Transcranial alternating current stimulation combined with sound stimulation improves cognitive function in patients with Alzheimer’s disease: Study protocol for a randomized controlled trial

open access: yesFrontiers in Aging Neuroscience, 2023
BackgroundThe number of patients with Alzheimer’s disease (AD) worldwide is increasing yearly, but the existing treatment methods have poor efficacy. Transcranial alternating current stimulation (tACS) is a new treatment for AD, but the offline effect of

Effect of Stimulus Contrast and Visual Attention on Spike-Gamma Phase Relationship in Macaque Primary Visual Cortex

open access: yesFrontiers in Computational Neuroscience, 2018
Brain signals often show rhythmic activity in the so-called gamma range (30–80 Hz), whose magnitude and center frequency are modulated by properties of the visual stimulus such as size and contrast, as well as by cognitive processes such as attention ...
