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 ...

Contribution of inter-trial phase coherence at theta, alpha, and beta frequencies in auditory change detection

open access: yesFrontiers in Neuroscience, 2023
IntroductionAuditory change detection is a pre-attentive cortical auditory processing ability. Many neurological and psychological disorders can lead to defects in this process.

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 ...

Electroencephalographic accompaniment of quantitative-qualitative blood pressure clusters in patients of Truskavets’ spa

open access: yesJournal of Education, Health and Sport, 2021
Background. Earlier we studied the autonomic and endocrine accompaniments of quantitative-qualitative blood pressure (BP) clusters of profile patients of Truskavets’ spa.

Causal evidence that intrinsic beta frequency is relevant for enhanced signal propagation in the motor system as shown through rhythmic TMS [PDF]

open access: yes, 2016
Correlative evidence provides support for the idea that brain oscillations underpin neural computations. Recent work using rhythmic stimulation techniques in humans provide causal evidence but the interactions of these external signals with intrinsic ...

Using and interpreting cost-effectiveness acceptability curves: an example using data from a trial of management strategies for atrial fibrillation [PDF]

open access: yes, 2006
Background: The cost-effectiveness acceptability curve (CEAC) is a method for summarizing the uncertainty in estimates of cost-effectiveness. The CEAC, derived from the joint distribution of costs and effects, illustrates the (Bayesian) probability ...

Rhythm of the beta-cell oscillator is not governed by a single regulator: multiple systems contribute to oscillatory behavior [PDF]

open access: yes, 2007
Pulsatile insulin output, paralleled by oscillations in intracellular Ca(2+), reflect oscillating metabolism within beta-cells in response to secretory fuels.

Modes of neural activity with cortical beta rhythm states. [PDF]

open access: yes, 2012
(A) Modulation of broadband amplitude by underlying rhythm can be thought of as population-averaged spike-field interaction. (B) “Released cortex” demonstrates a small amount of broadband power coupling to underlying rhythm phase, and the underlying ...

Association of beta-blockers and first-registered heart rhythm in out-of-hospital cardiac arrest:real-world data from population-based cohorts across two European countries [PDF]

open access: yes, 2020
AIMS: Conflicting results have been reported regarding the effect of beta-blockers on first-registered heart rhythm in out-of-hospital cardiac arrest (OHCA).

Circadian rhythm of urinary beta 2 microglobulin excretion in patients with a nephrotic syndrome [PDF]

open access: yes, 1987
The changes in urinary beta 2 microglobulin excretion during the day were studied in 20 patients with a nephrotic syndrome under standardized conditions and compared with the known circadian variations in urinary albumin excretion in the same patients ...
