transcranial current stimulation (tcs) is a neuromodulation method in which the patient is exposed to a mild electric current (direct or alternating) at 1-2 ma, resulting in an increase or a decrease in the brain excitability. this modi.cation in neural activities can be used as a method for functional human brain mapping with causal inferences. this method might also facilitate the treatments ...

Transcranial alternating current stimulation (tACS) seems likely to open a new era of the field of noninvasive electrical stimulation of the human brain by directly interfering with cortical rhythms. It is expected to synchronize (by one single resonance frequency) or desynchronize (e.g., by the application of several frequencies) cortical oscillations. If applied long enough it may cause neuro...

Abstract Objectives: Essential tremor (ET) is a disabling condition resulting from cerebello-thalamo-cortical circuitry dysfunction. Deep brain stimulation of the thalamic ventral intermediate nucleus (VIM-DBS) effective in managing severe postural and action tremor. Non-invasive electrical cerebellum has recently emerged as potential therapeutic option for these patients. In this study, we aim...

Abstract Background: Millisecond-precise targeting of ongoing brain oscillations with electric stimulation is an important goal to uncover brain-behavior relationships or treat neurological and psychiatric disorders related abnormal activity. The main challenge implement such a paradigm reliably assess activity despite artifacts that often exceed physiological signals by many orders magnitude. ...

Transcranial electrical stimulation (tES) has been widely used in the clinic and in behavioral neuroscience research. The effects of transcranial alternating current stimulation (tACS) range from treating depression to augmenting human cognition. Optimization of tACS protocols will require an understanding of the mechanisms of actions of externally applied electric fields on the brain. We have ...
