Beta Power May Mediate the Effect of Gamma-TACS on Motor Performance

open access: yes, 2019
Transcranial alternating current stimulation (tACS) is becoming an important method in the field of motor rehabilitation because of its ability to non-invasively influence ongoing brain oscillations at arbitrary frequencies.

Trackside Resource Management Scheme Based on Integration of TACS and CBTC Systems

open access: yesChengshi guidao jiaotong yanjiu
[Objective] Traditional signaling systems manage trackside resources using routing-based methods and calculate movement authority accordingly. In contrast, the TACS (train autonomous circumnavigation system) manages resources from the perspective of ...

Brain Oscillatory and Hemodynamic Activity in a Bimanual Coordination Task Following Transcranial Alternating Current Stimulation (tACS): A Combined EEG-fNIRS Study

open access: yesFrontiers in Behavioral Neuroscience, 2018
Motor control is associated with synchronized oscillatory activity at alpha (8–12 Hz) and beta (12–30 Hz) frequencies in a cerebello-thalamo-cortical network.

Robustness of a bisimulation-type faster-than preorder

open access: yes, 2009
TACS is an extension of CCS where upper time bounds for delays can be specified. Luettgen and Vogler defined three variants of bismulation-type faster-than relations and showed that they all three lead to the same preorder, demonstrating the robustness ...

Development of a microfluidic setup for the isolation and imaging of immune cells

open access: yesCurrent Directions in Biomedical Engineering
Specialised cells in the blood play an important role in controlling the immune responses. Thus, these cells are also valuable for the diagnosis and treatment of diseases such as autoimmune disorders and cancer.

Effects of Transcranial Alternating Current Stimulation and Neurofeedback on Alpha (EEG) Dynamics: A Review

open access: yesFrontiers in Human Neuroscience, 2021
Transcranial alternating current stimulation (tACS) and neurofeedback (NFB) are two different types of non-invasive neuromodulation techniques, which can modulate brain activity and improve brain functioning. In this review, we compared the current state

Effects of Transcranial Alternating Current Stimulation on Cognitive Functions in Healthy Young and Older Adults [PDF]

open access: yes, 2016
Recently, transcranial alternating current stimulation (tACS) has emerged as a tool to enhance human cognitive processes. Here, we provide a brief summary of the rationale behind tACS-induced effects on task-relevant brain oscillations and associated ...

Age-Dependent Effect of Transcranial Alternating Current Stimulation on Motor Skill Consolidation

open access: yesFrontiers in Aging Neuroscience, 2020
Transcranial alternating current stimulation (tACS) is the application of subthreshold, sinusoidal current to modulate ongoing brain rhythms related to sensory, motor and cognitive processes. Electrophysiological studies suggested that the effect of tACS
