Cerebellar transcranial alternating current stimulation modulates human gait rhythm

Neuroscience Research, 2020
Although specific brain regions are important for regularly patterned limb movements, the rhythm generation system that governs bipedal locomotion in humans is not thoroughly understood. We investigated whether rhythmic transcranial brain stimulation over the cerebellum could alter walking rhythm. Fourteen healthy subjects performed over-ground walking

Adaptive alternating current transcranial electrical stimulation (tACS)

2019 6th International Conference on Systems and Informatics (ICSAI), 2019
Traditional deep brain stimulation (DBS) has been proven effective in the treatment of neurological diseases, especially Parkinson's disease (PD), but the deep brain stimulation system can be further optimized to maximize therapeutic benefits. This paper proposes a programmable adaptive transcranial electrical stimulation, which consists of LFP ...

EEG feedback-controlled transcranial alternating current stimulation

2013 6th International IEEE/EMBS Conference on Neural Engineering (NER), 2013
Transcranial Alternating Current Stimulation (tACS) is a novel non-invasive brain stimulation modality. tACS passes weak, oscillating electric currents through the scalp to generate electric fields in the cerebral cortex. tACS has been shown to modulate both cortical oscillations and cognitive function in humans.

Prefrontal transcranial alternating current stimulation improves motor sequence reproduction

Behavioural Brain Research, 2019
Cortical activity in frontal, parietal, and motor regions during sequence observation correlates with performance on sequence reproduction. Increased cortical activity observed during observation has therefore been suggested to represent increased learning.

Retinal origin of phosphenes to transcranial alternating current stimulation

Clinical Neurophysiology, 2010
To examine possible retinal contributions to cortically induced phosphenes by transcranial alternating current stimulation (tACS) involving the visual cortex.Self-reported phosphene ratings and voltage-related potentials from the canthus, supra-orbital and sub-orbital regions of the right eye were measured to 2, 10 and 20 Hz tACS at 250 and 1000 microA

A Transcranial Alternating Current Stimulator for Neural Entrainment

2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020
Human cognition, perception, and memory are partially attributed to the synchronicity of neuronal dynamics in the prefrontal cortex, and growing evidence indicates that age-related decline in working memory is causally linked to dissonance in neuronal firing patterns.

Theoretical investigation of transcranial alternating current stimulation using laminar model

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Transcranial alternating current stimulation (tACs) has been gaining an increased interest in the last few years due to its capacity to modulate non-invasively high-order cortical processes, such as decision-making, language and sensory perception.

Personalized Theta Transcranial Alternating Current Stimulation and Gamma Transcranial Alternating Current Stimulation Bring Differential Neuromodulatory Effects on the Resting Electroencephalogram: Characterizing the Temporal, Spatial, and Spectral Dimensions of Transcranial Alternating Current Stimulation

Neuromodulation: Technology at the Neural Interface
The neuromodulatory effects of transcranial alternating current stimulation (tACS) on electroencephalogram (EEG) dynamics are quite heterogenous. The primary objective of the study is to comprehensively characterize the effects of two tACS protocols on resting-state EEG.A total of 36 healthy participants were recruited and were randomized into three ...

Physiology of Transcranial Direct and Alternating Current Stimulation

2016
Non-invasive brain stimulation with direct (transcranial direct current stimulation, tDCS) or alternating currents (transcranial alternating current stimulation, tACS) has been developed in neuroscience research in the last decades and since then has become an effective tool to induce neuroplasticity and modulate cognition and behaviour in humans.
