A meta-analysis showing improved cognitive performance in healthy young adults with transcranial alternating current stimulation

open access: yesnpj Science of Learning, 2023
Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation used for improving cognitive functions via delivering weak electrical stimulation with a certain frequency.

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.

After-effects of 10 Hz tACS over the prefrontal cortex on phonological word decisions

open access: yes, 2019
Introduction Previous work in the language domain has shown that 10 Hz rTMS of the left or right posterior inferior frontal gyrus (pIFG) in the prefrontal cortex impaired phonological decision-making, arguing for a causal contribution of the bilateral ...

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 ...

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.

Modelling and prototyping of a microfluidic cartridge for extracting immune cells from small volume blood samples

open access: yesCurrent Directions in Biomedical Engineering, 2020
Within the human blood immune cells assume specific functions to modulate and control the human immune response. Consequently, they are used for the diagnosis and treatment of autoimmune and hematologic diseases.

Noninvasive brain stimulation techniques can modulate cognitive processing [PDF]

open access: yes, 2019
Recent methods that allow a noninvasive modulation of brain activity are able to modulate human cognitive behavior. Among these methods are transcranial electric stimulation and transcranial magnetic stimulation that both come in multiple variants.

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

"Functional electrical stimulation (FES) impacted on important aspects of my life" - A qualitative exploration of chronic stroke patients' and carers' perceptions of FES in the management of dropped foot. [PDF]

open access: yes, 2012
Our purpose was to explore the impact of functional electrical stimulation (FES), as applied in the management of dropped foot, on patients with chronic stroke and their carers. A qualitative phenomenological study was undertaken.
