Beta band rhythms influence reaction times

open access: yeseneuro, 2022
AbstractDespite their involvement in many cognitive functions, beta oscillations are among the least understood brain rhythms. Reports on whether the functional role of beta is primarily inhibitory or excitatory have been contradictory. Our framework attempts to reconcile these findings and proposes that several beta rhythms co-exist at different ...

Beta rhythm modulation by speech sounds: somatotopic mapping in somatosensory cortex. [PDF]

open access: yesSci Rep, 2016
AbstractDuring speech listening motor regions are somatotopically activated, resembling the activity that subtends actual speech production, suggesting that motor commands can be retrieved from sensory inputs. Crucially, the efficient motor control of the articulators relies on the accurate anticipation of the somatosensory reafference.

Beta and Gamma Rhythms Go with the Flow [PDF]

open access: yesNeuron, 2015
Information flows through visual areas in opposite directions during "bottom-up" intake of current stimuli and "top-down" processes such as attention or memory. In this issue of Neuron, Bastos et al. (2015) report that rhythms of different frequencies coordinate bottom-up and top-down information streams.

The Effect of Neurofeedback Training on Dynamic Balance of Young Men [PDF]

open access: yesرشد و یادگیری حرکتی ورزشی, 2015
Physical balance is one of the important factors in daily sport activities.Dynamic balance helps maintain the balance of those forces imposed on body insports and an increase in this balance improves motor and sport performance.

A modelling study of beta-amyloid induced change in hippocampal theta rhythm [PDF]

open access: yes, 2011
Many dementia cases, such as Alzheimer’s disease (AD), are characterized by an increase in low frequency field potential oscillations. However, a definitive understanding of the effects of the beta-Amyloid peptide, which is a main marker of AD, on

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 ...

Impact of Renal Impairment on Beta-Blocker Efficacy in Patients With Heart Failure. [PDF]

open access: yes, 2019
BACKGROUND: Moderate and moderately severe renal impairment are common in patients with heart failure and reduced ejection fraction, but whether beta-blockers are effective is unclear, leading to underuse of life-saving therapy.

Human motor cortical activity is selectively phase-entrained on underlying rhythms.

open access: yesPLoS Computational Biology, 2012
The functional significance of electrical rhythms in the mammalian brain remains uncertain. In the motor cortex, the 12-20 Hz beta rhythm is known to transiently decrease in amplitude during movement, and to be altered in many motor diseases.

Cross-frequency phase-amplitude coupling as a mechanism for temporal orienting of attention in childhood [PDF]

open access: yes, 2018
Temporal orienting of attention operates by biasing the allocation of cognitive and motor resources in specific moments in time, resulting in the improved processing of information from expected compared with unexpected targets.

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.
