Impact of tDCS and HD-tDCS on tinnitus perception: A scoping review
2021Tinnitus is the auditory phantom perception of a sound that severely affects the quality of life of over 300,000 people in the United Kingdom alone. Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation tool, which has been investigated as a potential tinnitus management option since 2006. This study aimed to investigate the

Abstract A circuit is presented which uses FADCs for instantaneous time digitization at regular clock intervals. It allows the construction of pipeline TDCs with a resolution of a small fraction of the clock time. In measurements with a 100 MHz, 8-bit FADC a resolution of ≈ 30 ps has been obtained.

tDCS possibly stimulates glial cells
Clinical Neurophysiology, 2012Explore the possibility that transcranial direct current stimulation (tDCS) of the brain affects glial cells.Cable theory is used to estimate roughly transmembrane potential in neurons and glial cells. tDCS is additionally compared to neuronal stimulation techniques for which the mechanisms are well known.Theoretical calculations indicated that tDCS ...

Designing Synchronizers for Nutt-TDCs
2019 5th International Conference on Event-Based Control, Communication, and Signal Processing (EBCCSP), 2019Applications requiring both high resolution time measurement and large dynamic range demand for the integration of high-performance Time-to-Digital Converters (TDCs) and coarse counting methods which operate asynchronously. When using two asynchronous counting methods, the use of a synchronization mechanism is mandatory to correct metastability errors.

Evaluating the effects of tDCS in stroke patients using functional outcomes: a systematic review
Disability and Rehabilitation, 2020Background and purpose Transcranial direct current stimulation (tDCS) has been extensively studied over the past 20 years to promote functional motor recovery after stroke. However, tDCS clinical relevance still needs to be determined.

Multimodal Association of tDCS with Electroencephalography
2021In the field of neuromodulation, we have observed an increase in the popularity of approaches that combine transcranial electrical stimulation (tES) with additional methods to establish, in vivo, the neurophysiological consequences of a given experimental or therapeutic manipulation. Research in the development of multimodal approaches has provided new

tDCS and Functional Connectivity
2021Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that modulates the cortical excitability of the human brain by applying weak direct currents on the scalp through both anodal and cathodal electrodes. However, the mechanisms of tDCS action are not yet fully understood.
